Trenbolone – guide A-Z

What is a trenbolone? What effects can you expect from using this substance? What side effects does this steroid have? Where can I buy Trenbolone? These and other questions are answered in the following article

What is a trenbolone?

Trenbolone, also known as Tren, is the second most popular anabolic steroid used in bodybuilding after testosterone.

It is a derivative of Nandrolone, however, its effects are significantly different from this steroid.

Trenbolone acetate

Trenbolone is about 5x stronger than testosterone. It is able to completely change a person’s physique even during one cycle.

It is most often used during weight reduction, because it allows to keep practically 100% of muscles despite the calorie deficit. However, due to its enormous anabolic strength it is also suitable for gaining muscle mass.

I would just like to remind you that under no circumstances should trenbolone be used by people under 18 years old!

Forms and half-life

There are mainly 3 forms of trenbolone: acetate, enanthate and hexahydrobenzylcarbonate. They differ only in half-life and in the percentage of the substance in the product.

trenbolone acetate

half-life: 1 day

Content of the active substance in the product: 82%

Trenbolone acetate

The most popular form of trenbolone. Due to its short ester, the first effects of the substance can often be observed in the first week. This form requires daily injections in order to maintain a stable concentration.

PCT can be started about 3-4 days after the end of the cycle (provided that the testosterone is equally short).

trenbolone enanthate

half-life: 4.5 days

Content of the active substance in the product: 70.6%

trenbolone enanthate

Less popular form of trenbolone, but also quite common on the market. For the first visible effects you have to wait about 2 weeks. Due to the longer half-life the injections can be made 2-3 times a week.

With this form you should start PCT about 2 weeks after the end of your cycle (provided you take testosterone with the same or shorter half-life).

trenbolone hexahydrobenzylcarbonate

Half-life: 5-7 days

Content of the active substance in the product: 65.8%

Rarely used type of trenbolone. It is usually only found in blends. As in the case of enanthate, the injections should be made 2-3 times a week and PCT should be started about 2 weeks after the end of the cycle.


tri tren

A mixture of the three types of trenbolone mentioned above. It should work very much like sustanone in case of testosterone. Due to the mixing of fast and slow acting esters, the first effects of tri-train appear quite quickly and at the same time the concentration of the agent in the blood remains fairly stable, allowing for less frequent injections. In case of tri-train injections should be made every 1-2 days.

PCT should be started about 2 weeks after the end of cycle.

RIP blend

rip blend

Mixture of fast forms of testosterone, trenbolone and masterone. It gives phenomenal results when it comes to fat burning. It usually occurs at a concentration of 200mg/ml. In case of this mixture it is necessary to make injections every day.

PCT should be started about 3-4 days after the end of the cycle.


Fat burning – The most popular use of Trenbolone. Although it is not a thermogenic agent itself and does not burn fat, thanks to very high anabolic activity it increases the body’s energy requirements and allows the body to maintain practically 100% of its muscles during periods of caloric deficit.

Muscle mass gain – Trenbolone is about 5x stronger than testosterone. While, of course, the increase in the amount of substances used is not perfectly proportional to the increase in muscle mass, the effects obtained during the use of Trenbolone are phenomenal. I think I have not yet met a person in my life who was disappointed with the gains achieved with this steroid.

Visibility of veins – Similarly as with Masteron or EQ, the visibility of veins increases. This is related to, among other things, loss of fat tissue, decrease in the amount of water retained in subcutaneous tissues, increase in blood density and in some cases increase in blood pressure.

Increased strength – Trenbolone is one of the best steroids for rapid strength gain. This is due to both its high anabolism and high androgenicity. Highly androgenic agents strengthen the nervous system and increase aggression during workouts. And the high anabolism of the substance ensures a very fast increase in muscle mass and thus strength.

Self-confidence – Trenbolone definitely increases self-confidence. It is a particularly positive feature for shy people. Unfortunately, unlike e.g. testosterone, which increases “aggression” during workouts, trenbolone often increases it also outside the gym. Obviously, I don’t mean getting furious for any reason, however, whem using tren, I’m undoubtedly much more often annoyed by things I wouldn’t normally pay attention to.

Sexual drive – Trenbolone raises my libido like no other substance. Even compared to high doses of testosterone, the sexual drive increases 2-3 times.

It also temporarily increases the size of the erect penis by a few percent – this is probably due to an increase in blood density, stronger than normal arousal and an stronger muscles pumping blood into the penis.

Increased sexual attraction – I know it sounds quite controversial and most people might say that the reason is increased self-confidence or improved physique, but I am convinced that something else is behind it. I don’t know if pheromones or something else is responsible, but every time I start a cycle of highly androgenic steroids, the number of women interested in me increases significantly. I usually see an increase in the number of women flirting with me as early as the first week, so it is certainly not the result of a change in physique. What’s more, I’ve also observed that my wife’s libido increases significantly when I use Trenbolone.

Beard – As the popularity of growing a beard is back in recent years, many people may enjoy this “side effect”. Trenbolone increases the amount of DHT hormone, which is responsible for stimulating the hair follicles located on face.


Trenbolone is undoubtedly one of the strongest steroids available today. It gives phenomenal results in terms of fat burning, muscle growth and strength. Honestly, in my entire career I have not yet met anyone who would be disappointed by the effects of this drug.

I often get questions like how many muscles I can get by using trenbolone. This is a question that no one can really answer. How much muscle you gain with steroids depends on your genetics, the amount of substances you use, the length of your cycle, your weight, your diet, your training and many other factors. However, with Trenbolone you can certainly expect to gain a few kilograms of pure muscle mass.

Before and after

Side effects

Hair loss – As we know, one of the main causes of hair loss is the negative effect of DHT on hair follicles. Because trenbolone is a strongly androgenic steroid, the DHT concentration during the cycle increases significantly and the number of hair loss increases.
However, it is worth remembering that steroids usually only accelerate hair loss, so if you are not predisposed to baldness, this problem will probably not affect you.

HPTA blockade – A typical side effect of anabolic steroids. When using steroids, the body detects increased levels of androgens and stops their natural production. When you stop using steroids, your hormone production slowly returns to normal. To speed up this process and prevent muscle catabolism PCT drugs are used.

Cardio – Trenbolone is known for its negative impact on the stamina. Unfortunately, there is little you can do about it. If you are very concerned about maintaining your condition, you can simultaneously use GW-501516/Kratom/EQ.

Acne – When using Trenbolone your skin will get oily much easier. People with skin problems often develop acne. However, it can be prevented by using small doses (10mg/day) of isotretinoin – trade names Izotek/Accutane.

Insomnia – This side effect occurs mainly in people using very high doses. Tren is a very strong steroid, which increases the training capacity of the body several times. Most people, however, continue with their standard workouts 3-4x a week. As a result, although we are mentally tired, our body is rested and does not need sleep. When you increase the workout volume, this side effect does not appear.

Tren cough

This side effect occurs extremely rarely and is only caused by the mistake of the person making the injection. A characteristic cough only occurs if you insert some of the substance into the vein instead of the muscle/fat tissue. In such a case, Tren with blood enters the lungs and temporarily disrupts their function. This is quite an unpleasant phenomenon, but completely harmless. The cough usually disappears after about 2-3 minutes. In extreme cases (if you accidentally insert Trenbolone into a vein instead of a muscle), you may experience temporary dizziness caused by a reduced oxygen concentration in your body. In such cases you should sit down and wait 2 minutes. During this time the body will remove the substance from the lungs by itself.

In case of lower doses of steroids (<1ml/day) coughing can be avoided by using subQ injections. In this case, the needle is not long enough to reach any larger vein and transport the oil.


The dosage you should use depends of course on your gym experience, your weight and how long you have been using anabolic steroids.

Trenbolone should always be combined with testosterone! Otherwise, there will be additional side effects such as: zero libido, dry joints, reduced mood and much more.

In my opinion, the best dose for the first cycle involving Trenbolone is 350mg/week combined with 175mg/week of testosterone. These are relatively small doses, however, sufficient to build up a large amount of muscle mass. The main advantage of such a dosage is that there is no need to use aromatase inhibitors.

If you have been using steroids for a long time you can start with 2x higher doses, i.e. 700mg/week of trenbolone + 350mg/week of testosterone. In my opinion, the 2:1 ratio is the best in terms of ease of control of Estraidol and quality of gains.

Daily injections are very important when using short trenbolone esters. These are necessary to maintain a stable amount of substances in the blood. If you decide to take less frequent injections, you must take into account the possibility of mood swings and a strongly lowered libido.

Best tren stack

Trenbolone also works well with other steroids. The most popular combination is the RIP blend, a combination of testosterone, trenbolone and masterone. This is one of the most effective stacks for fat loss. But it can be combined with practically all steroids. However, I do not recommend combining it with other Nandrolones, as in such a combination estradiol, progesterone and prolactin problems may be difficult to control.

Cycle example A-Z

1-12 week:Trenbolone acetate0.5ml every day
Testosterone propionate0.25ml every day
13-16 week:Clomid50mg daily
Nolvadex20mg daily

I think this is the perfect first cycle utilizing trenbolone. One of the biggest advantages of this type of cycle is that thanks to the 2:1 ratio, the risk of having problems with too much oestradiol is negligible, so you probably won’t need any aromatase inhibitors.

The cycle may have associated side effects – a decrease in libido and gynecomastia – in people sensitive to prolactin/progesterone. At a ratio of 2:1 they occur extremely rarely, however, just in case you need to buy at least a few tablets of cabaser in order to be able to lower the prolactin and progesterone immediately if necessary.

Although nandrolones themselves reduce the prolactin, they also significantly increase the sensitivity of the body to this hormone. Taking trenbolone with too high a dose of testosterone (testosterone is needed to maintain proper body function), without aromatase inhibitors leads to an increase in Estradiol levels, which also results in an increase in prolactin and, consequently, in the above-mentioned problems.

It should be remembered that gynaecomastia is 100% reversible within the first few weeks after its occurrence (all you need to do is lower the concentration of estradiol and prolactin in the body).

In order to avoid hormone fluctuations, it is best to perform the injections daily. In case of low doses of steroids (<1ml/day) it is possible to use subQ method using a tiny insulin needle. With this method a maximum of 0.5ml of oil can be injected at once – otherwise bubbles form under the skin, which look like an insect bite and which last about a week.

Nolvadex pct

After completing the cycle, wait about 3-4 days (for short esters) and start PCT. For this purpose, purchase Clomid and Nolvadex. These are SERMs, which increase LH levels and thus signal the body the need to resume testosterone production.

During the cycle the body detects the presence of sufficient amount of androgens and stops their endogenous production. After the cycle, the body needs several weeks to restore hormone production to normal levels.

Using PCT allows the body to recover faster and avoid the side effects of too little testosterone – depression, loss of muscle mass, weak libido, etc.

After completing the cycle you should wait at least 12 weeks before starting another one.

Where to buy trenbolon online?

Unfortunately, most of the stores on the market selling steroids turn out to be scammers and after transferring money to their account you will never receive the items you ordered. It is equally popular to lower the concentration or sell different drugs than those declared on the packaging. The latter case is particularly dangerous. When using a different substance than you ordered, you do not know its mechanism of action and potential side effects. Therefore, you also have no idea how to counteract them, which can result in long-term problems.

For this reason, you should only buy steroids from trusted sources. Preferably from people you know personally and who you can turn to in case of problems.

If you are not able to do so, below is a list of shops that I have used in the past and in which you can buy Trenbolone.


Prestige pharma

Probably the first shop where I bought steroids online and where I wasn’t cheated. It used to operate under the .com domain, but it suspended its operation for a few years due to legal problems. A few months ago they resumed sale in a new store. Until now I ordered RIP blend, Winstrol, Primobolan, Trenbolone, Aromatasin and HCG from them and all the substances worked superbly. The biggest advantage of this shop, however, is the fact that PCT, AI and Cabaser products come from pharmacies and the steroids themselves from very popular manufacturers. This gives almost 100% confidence that they will work as they should.

EDIT: After contacting the shop owners I managed to get a discount coupon for blog readers: RICHARDJ10

Currently one of the most popular steroid stores in the world. I have ordered various products from them in the past and their quality has always been very good. In recent months they have rebuilt the site and changed the names of the products (I’m not sure if these are only changes of product names or also suppliers), which makes it difficult to find the needed substances. Nevertheless, I can definitely recommend this shop. I also recommend that you contact the staff via chat – they are very helpful and willing to give you discount codes. In addition, if you order several items of the same agent, an additional discount is automatically calculated.
