Tren (Trenbolone Acetate) Steroid for Bodybuilding

Trenbolone Acetate is a well-known steroid that increases muscle mass. That is why sportsmen usually use this drug to build up physique. Bodybuilders often take Trenbolone during the cutting phase because it helps to burn fat faster. Some specialists claim that Trenbolone stimulates appetite. Yet this information is not proven by laboratory testing.

Tren steroid is a powerful anabolic drug. It’s approximately four times stronger than Testosterone. The final result Trenbolone Acetate brings to athletes is:

• Muscle build-up;
• Loss of fat and unwanted weight;
• Increased physical strength.

This steroid has severe side-effects. The most unpleasant negative effect is a decrease in natural testosterone production. It causes a range of possible health issues, such as:

• kidney and liver failure;
• acne, abnormal sebum production, stretch marks, etc.;
• testicle size changes, etc.

Let’s take a closer look at the Tren steroid in our article to analyze its strong and weak points.

Is Tren (Trenbolone Acetate) Legal?

In some countries, Tren is legally used for veterinary purposes. This product, in combination with other components, helps to grow strong and healthy livestock. Trenbolone steroids appear under various brand names. Some of them are famous for vet use, others – among bodybuilders. The human body absorbs the pure form of tren anabolic steroids very fast. That is why manufacturers combine Trenbolone Acetate with other components. The blood receives the nurious complex that stimulates muscle growth. Trenbolone supplements provide prolonged effects and results become more stable. The most popular Tren drug brands are:

• Revalor;
• Finajet;
• and other AAS (anabolic & androgen steroid) supplements.

These products are legal in many countries. But customers need to have a vet physician’s or doctor’s prescription to purchase Trenbolone Acetate in any available form (pills, liquid for injections, etc.). Illegal sale of Tren drugs is under prohibition in the USA and Australia. There is a more tolerant attitude to trenbolone supplements in Great Britain. Bodybuilders can buy this steroid for personal use without any problems there. At the same time, Tren sales without a medical license are not allowed on the UK territory.

Trenbolone Steroid and Supplement Use in Bodybuilding

This steroid promises fast results for bodybuilders. Trenbolone can change an athlete’s physique dramatically in 14-16 days of use. It is several times more powerful than Testosterone (source). So, the effect is more impressive and swift-handed. Bodybuilders use Tren drugs to shred their body fat and increase their muscle mass.

It is important to eat balanced meals and train every day. This way you can achieve desirable physical form and well-defined body lines faster. Athletes also notice the stability of results even after the end of the trenbolone steroid cycle.

At the same time, Tren and its supplements have dangerous side effects. The shutdown of natural testosterone production caused by Trenbolone use harms athletes’ health. So, it is normal that people search for safe alternatives with the similar building up effect.

There is a Legal, Natural, And Safer Alternative to Tren Steroid – Trenorol

Trenorol is a 100% organic dietary supplement with a powerful effect. It works similarly to Trenbolone, yet has no major side-effects. The super-smart mixture of natural components makes the supplement work for two goals simultaneously. First, it helps your muscles to grow faster. Second, it increases your energy production and encourages fat loss.

Plus, Trenorol is a great tool to increase your vascularity. The supplement stimulates red blood cell formation. This effect is crucial for bringing more oxygen to your muscles, it also makes your veins more visible.

Main Ingredients:

Beta-Sitosterol is a natural testosterone booster extracted from herbs. Unlike many hormone-stimulators, the herbal sterol is beneficial to men’s health. It prevents free testosterone from converting to DHT and decreases the risk of any hormonal disorders. Beta-Sitosterol also decreases the sugar level in your blood. It prevents many health issues like diabetes and helps to stimulate healthy fat loss.

Nettle Leaf Extract is one of the strongest natural testosterone stimulators. It’s also a great source of iron, which is beneficial for your muscle growth. Nettle Leaf Extract supports your immune system and stimulates better oxygen supply.

Samento Inner Bark is a great anti-inflammatory ingredient. This natural component works safely to speed up your post-training recovery. It’s also a great helping tool to cure your traumas and to prevent injuries of your joints.

Pepsin is a natural enzyme responsible for protein digestion. Trenerol supplies extra pepsin for your body to consume protein more easily and faster. As a result, your body gets more building material for your muscles and you don’t even have to add extra food for that.

Trenbolone Effects and Benefits – How Does It Work? 

Athletes use trenbolone for muscle building up effect. This is the main benefit of Tren drugs. The notable feature of the trenbolone acetate is the ability to change individuals’ physical condition. The powerful compound provides faster effects than testosterone injections and other AAS. Results are stable and fast-achieved. Let’s take a closer look at each benefit of Tren steroids.

Tren steroids provide bodybuilders with the muscle growth effect. This is the primary feature of trenbolone. Supplemental benefits are faster fat loss, a better physical condition, and body strength. Bodybuilders take trenbolone steroids and get fast and stable results. Different chemical reactions and changes in the organism take place. 

Tren steroids block natural testosterone production but improve other internal processes. Trenbolone initiates the following changes:

1. Use of  Tren drugs improves protein synthesis and nutrient efficiency.
2. Its use provides more IGF-1 (Insulin-like Growth Factor) for the individual’s organism.
3. The RBC (red blood cells) level increases as well.
4. Nitrogen retention is boosted.
5. Cortisol levels are reduced.

It is worth taking a closer look at each physiological and chemical process. Trenbolone use stimulates various systems in the human organism. Tren steroids provoke different reactions.

Improved Protein Synthesis

Trenbolone drugs speed up muscle growth through increased protein synthesis. The drug changes natural processes, increasing the amount of new protein cells. Produced cells become building materials for muscle tissue. Intensive training and regular workouts also play a role in the muscle-building process. This way steroids can boost protein synthesis in the ultimate way. 

Trenbolone acetate has a positive impact on protein (source) consumption. This biological process becomes improved through optimal digestion of high-protein food. Tren steroids help to derive amino acids from protein and shuttle them to muscles. All the stages of synthesis turn out to be faster and more effective. 

Trenbolone drugs are not efficient enough if the individual does not have enough physical load and a proper diet. Muscle growth is possible when a comprehensive approach takes place. If protein is well-produced in the organism, there are enough building blocks for muscle development. The improved protein synthesis allows bodybuilders to achieve better athletic performance in shorter terms. 

More IGF-1

One of the most important hormones in our body is IGF-1. It plays an important role in strong ligaments and tendons. IGF helps the human’s central nervous system to receive necessary nutrients.  Muscle tissue formation and the pulmonary system work would be impossible without a healthy level of IGF-1.

Insulin-like Growth Factor production takes place in the human liver. This endocrine hormone handles cell growth in the organism. Tren steroids increase IGF-1 production. It helps all the tissues to recover easier and faster. Cell division becomes quicker as well. Boosting the Insulin-like Growth Factor leads to:

• Better metabolism;
• Easier fat loss;
• Faster regenerative processes;
• Stimulated cell division;
• More effective anti-oxidant function;
• Stronger muscles.

Trenbolone increases the level of the IGF-1 hormone. The most optimal method of Tren steroid use is injection. This way fat loss and muscle development become faster. Insulin-like Growth Factor production is very necessary for protein synthesis. These processes depend on each other. Tren steroids allow hormonal systems to work better. But individual parameters of each human body should be taken into account. IGF-1 and protein imbalance can cause serious health problems.

Increased RBC

Red blood cells transport oxygen from the lungs to tissues during any physical activity. Tren steroids increase RBC production on a regular basis. It means that the blood buffering process does not depend on the intensity of training. The metabolic cycle has the same level of intensity both when athletes train and relax. Tissues get oxygen regularly, and metabolism speeds up as well.

Improved blood cycle initiates hemoglobin production that makes muscle tissues firmer. Sports experts noticed some dangers that increased RBC leads to. For example, people with cardiac failure, liver, or kidney diseases cannot use Tren. Increased red blood cell content harms individuals’ health with these health issues a lot. 

Reduced Cortisol

The high cortisol level is harmful for our body. It means that some of our hormonal systems work improperly. The adrenal and pituitary glands handle cortisol production. The hypothalamus also takes part in the process. If the amount of cortisol increases, our body feels stressed. Muscles and the immune system become weak. People can notice a very changeable mood and extra weight on the abdomen and face. 

Tren anabolic steroids reduce cortisol. It improves many body functions. Stress hormone levels become lower and muscle strength grows when cortisol drops down. If the cortisol level is normal, blood sugar levels are also under control. Even so, artificial hormonal changes can harm athletes’ health. Doctors advise you to be extra careful with Tren use if the following symptoms are noticed:

• Hormonal imbalance;
• Skin problems;
• Organ failures or other internal diseases.

Improved Nutrient Efficiency

Trenbolone is one of the most powerful AAS. One of its notable features is the ability to boost metabolism processes. Bodybuilders get more nutritional elements from food, drinks, and supplements. Improved nutrient efficiency stimulates:

• Fat burning;
• Muscle growth.

Note that some individuals have an excessive appetite using Tren steroids. When all the organism processes become faster, brainwaves inform athletes about hunger more often. 

Nitrogen Retention

Nitrogen balance is necessary for building muscles. Protein contains additional nitrogen molecules. Bodybuilders who monitor their daily protein intake will not suffer from N-lack. When Trenbolone improves protein synthesis, it regulates nitrogen balance as well. 

Fast muscle-building takes place when nitrogen efficiency is high. Positive N-balance provided by Tren steroids is the most optimal state for athletes. Workout recovery becomes quicker with increased nitrogen retention. Muscles become stronger, and the body becomes more powerful. Improved nitrogen efficiency brings the body into an anabolic state. Note that N-imbalance is possible. Consult your doctor before using Trenbolone Acetate.

Trenbolone Results: What to Expect on Tren?

Tren steroids bring fast results. Trenbolone supplements enhance hormonal production and muscle growth. It should be used during bulking and cutting cycles to provide desired physical effects. Most bodybuilders prefer the injectable form of Tren. Athletes administer injections according to the adjusted scheme. 

Some of the results are available below. Look at the BEFORE and AFTER photos to see the difference. Bodybuilders note that they use the Tren AAS in combination with intensive workouts. The most amazing results are possible if athletes pay attention to three important aspects of building muscles:

• Regular injections;
• Proper nutrition;
• Intensive workouts.

Strength, Muscle Mass, Vascularity, Pumps, and Fat Loss from Trenbolone

Trenbolone provides strength and stimulates muscle growth. Above-mentioned Before & After photos show that the correct dosage of the drug is required. If a bodybuilder does not miss injections, trains regularly, and eats healthy food, the result will come fast. Let’s take a look at them for a better understanding of trenbolone acetate:

1. Muscle mass – this effect is visible even with small doses of Tren drugs. When muscle tissues become stronger and firmer, muscle mass starts to grow. They turn out to be bigger in volume. Trenbolone helps the human organism to increase muscle mass even with a calorie deficit. 
   
2. Vascularity – Tren helps to gain high-level vascularity and attractive ripping muscles. The effect depends on the cycle of Trenbolone drug use.
   
3. Pumps – Trenbolone shreds muscles without natural water retention. The effect comes 2-3 weeks after the use of steroids. Vascular physique becomes improved and muscles get stronger. 
   
4. Fat loss – Trenbolone reduces extra weight and builds up muscles at the same time. That is why bodybuilders like to use this AAS. If athletes only want to lose fat, small doses of Tren steroids will be enough. The fat percentage will decrease in several weeks after the first Trenbolone cycle. 

Bodybuilders often call trenbolone acetate Tren A. Dosing properly is critical for any willing individual to get excellent results. If the dose is suitable for your body, you may avoid side effects. Proper dosages prevent cancer development and skin conditions.   

Trenbolone Dosage 

Both male and female athletes can use Tren drugs. At the same time, the dosage varies for women and men. A doctor’s advice is required for all bodybuilders as well. Trenbolone might be dangerous for health if an individual has chronic diseases. The most famous personal trainers recommend starting with the small weekly dosage:

• Female athletes should use about 200-250 mg of Tren A per week. This dosage should not be exceeded during the first Trenbolone use cycle.
  
• Male bodybuilders can start with 300 mg. After 1-2 weeks of Tren steroid use, men should consult their doctor. If their physical health condition is normal, the dosage can be increased by 50 mg per week. 

Note that there are proper Trenbolone cycles to follow. You should research them and begin drug use at the proper time. Here is a table with the major Tren A cycles to take into consideration.

Tren-Ace: Bulking and Cutting Cycles, their Lengths

For Male Bodybuilders

For Female Bodybuilders

*Advanced course does not need an increase of daily dosage. 100 mg is enough for injection. Athletes begin to administer injections every day. For example, the first Tren A use this week was on Monday. Tuesday will be a skipped day, free of injections. Wednesday and Thursday – time to administer injections. Friday is a missing day. Saturday and Sunday will be the days of Trenbolone use.

Note that each athlete has his/her own body differences. Body structure, level of preparation, and other parameters are different. This means that these tables with cycle descriptions are only average examples of Tren dosage. Do not start Trenbolone courses without consulting a doctor. Get medical prescriptions before starting any Tren steroid cycle as well.

Do not exceed the dose of 800 mg Tren per week. Note that all cycles vary. Use Tren drugs during bulking and cutting cycles properly. Your results will be stable even if the weekly dosage is 600-700 mg. The correct dosage and your responsibility will steer you clear of illnesses and side effects. 

Tren (Trenbolone) Side Effects

Some experts call Trenbolone a drug with severe side-effects. The wide range of body’s negative reactions proves this statement. Experienced bodybuilders recommend examining your health before any steroid use. The desire for astonishing muscle mass and fat loss can turn into cardiovascular diseases, hormonal imbalance, etc. 

The list of the most dangerous conditions Tren use sometimes leads to is the following:

• Hypogonadism;
• Increased sweating;
• Insomnia;
• Estrogenic and progestogenic disorders;
• Androgenic imbalance;
• Cardiovascular illnesses;
• Tren cough.

Hypogonadism

We know that Tren stops testosterone production in the individual’s organism. Hypogonadism is one of the first problems male bodybuilders face. The lack of testosterone causes hormonal deficiency and provokes the following symptoms:

• Problems with erection and ejaculation;
• Depression;
• Decreased libido;
• Insomnia;
• Facial hair loss (optionally truncal alopecia);
• Bad concentration, memory;
• Lack of energy.

If you notice these symptoms and feel bad, do a blood test and check your testosterone levels. Hypogonadism is a very dangerous disorder. It can lead to carcinoma and agenesia.

Increased Sweating

People feel discomfort when they are sweating. Tren injections provoke intensive sweat production. Imagine that you are sweating all the time. Bodybuilders find this side effect annoying. You cannot sleep, eat or communicate with friends. Some athletes do not face this problem. Those who felt increased sweating would understand the matter.

Medical specialists state that sebaceous glands work nonstop. It signals about hormonal imbalance. Body examination is necessary to exclude other causes. Increased sweating might be a symptom of some dangerous disorders. 

Insomnia

Steroid use often causes insomnia. Bodybuilders feel tired and exhausted at night. But they cannot sleep deeply. Long-acting sleeping pills can solve this problem. But this solution is dangerous in most cases. Tren improves various internal processes. So, the reaction to sedatives can be unpredictable.

Consult your doctor to find a reason for insomnia. If you have a high adrenaline level or sex hormone imbalance, start your treatment. Stop the Trenbolone course and improve your health. Your body should have a rest at night.

Estrogenic and Progestogenic Disorders

Tren drugs can cause reproductive hormonal disorders. Estrogen and progesterone imbalances are very harmful both to male and female health. They affect fertility and metabolism. If reproductive hormonal imbalance stays untreated for a long time, the cardiovascular system may be overloaded. Bone health also suffers from estrogenic and progestogenic disorders.

Female bodybuilders may have unstable menstrual cycles, early menopause, and agenesia. Men are more sensitive to testosterone changes. At the same time, they can get the following symptoms:

• Immune disorders;
• Sexual vigor problems;
• Sperm absence.

Androgenic Imbalance

Experts call this condition hyperandrogenism. This disorder is notable for its androgenic imbalance. Female athletes who use Tren steroids often have high levels of androgenic hormones. This disorder can bring more serious endocrine problems. Women usually see the following symptoms:

• Skin conditions (acne, skin inflammation, etc.);
• Irregular menstruation;
• Increased hair growth on the face, belly, back, and other body parts.

Doctors may ask the female bodybuilder with these symptoms to do a blood test. If the level of cholesterol is high, the disorder is confirmed. Doctors prescribe medical-based courses for treatment. Athletes should stop Tren A use until they finish the therapy.

Cardiovascular Illnesses

Tren steroids speed up blood circulation. That is why the cardiovascular system often suffers. Too high heart rate is one of the most widespread side effects. Bodybuilders feel a fast heartbeat during training. Athletes should not ignore this condition. Dangerous cardiovascular illnesses can develop:

• CAD (coronary artery disease);
• Heart attacks;
• Arrhythmia;
• Venous thrombosis, etc.

Tren Cough

The most specific side effect of Trenbolone use is Tren cough. Experts call it short-lived and do not consider this condition dangerous. Tren cough appears a minute after the injection. Tren liquid hits a blood vessel and our body provides its reaction. Lungs provoke a cough to exhale unknown agents. 

Our organism does not want to accept Tren metabolites. The dry cough is such a method of the human body to set free from harmful particles. It lasts several minutes. Bodybuilders can feel a metallic taste after a Tren cough.

Trenbolone Form: Oral, Injections, Pills

Tren drugs are available in injection form. Athletes can buy liquids online, in the drug store, and other special markets. Check whether your local regulatory environment allows or forbids purchases of trenbolone acetate. Check your legal base first.

Some manufacturers include Tren in other anabolic drugs. There is no oral form with pure contents of trenbolone to buy. Pills are not as effective as injections. Use the tren liquid form and administer this drug regularly.

Trenbolone Acetate vs Trenbolone Enanthate

Both steroids have the same primary element. It is Trenbolone. The main difference between Tren A and Tren E is their speed of acting. Enanthate Tren has a longer cycle of absorption. Tren A has more active esters. So, all the processes take a shorter period of time. Other differences are available in the table below:

Recommendations for Tren A Post Cycle Therapy

We have described Tren cycles in solo mode. This steroid can be used without other supplemental elements. But it does not mean that PCT (post cycle therapy) is not required. Tren A stimulates many internal processes, hormonal systems, and muscle tissues. That is why it is necessary to go through the final stage of Trenbolone use correctly. 

The post cycle therapy lasts 4 weeks. To help your natural testosterone to come back to a normal level, you need to administer Clomid injections during the next four weeks. The algorithm of PCT is not complicated:

1. Finish your Tren use.
2. Have several days of rest.
3. Buy Clomid in liquid form or select pills.
4. Administer injections with Clomid every day / Take pills containing Clomid every day.
5. The daily dose is 50 mg of this active element.
6. PCT finishes in 4-6 weeks.

Note that you need to consult a doctor each week and do blood tests. Examinations and regular testing allow you to see how the hormonal system works.

Stacking Trenbolone

Tren steroids are effective as the only component to use for bulking and cutting. But some bodybuilders prefer to combine this drug with other AAS. Stacking Trenbolone with other steroids is possible. Complex courses bring faster effects and more stable results. Here is a list of anabolic steroids that are compatible with tren:

• Winstrol;
• Dianabol;
• Masteron.

Note that specialists do not recommend beginners to start with stacked courses. Trenbolone solo use is more suitable for newbies. For cutting cycles with a stacking complex of steroids, the third component is needed. Test Propionate is necessary for excellent effects and a well-balanced steroid cycle.  

Veterinary Use of Tren

Trenbolone Acetate is the main accruing element of Finaplix (Finaplix-H). Farmers and representatives of the livestock industry use this drug to raise good cattle. Finaplix has a liquid form. Farmers administer injections according to instructions. Finaplix contains about 90% of Tren in its contents. It allows to increase cattle’s muscle mass and have healthy livestock.

Veterinary medicine uses Trenbolone for animals’ treatment as well. Sometimes it is necessary to speed up internal processes and save the life of someone’s pet or livestock.
