What is Trenbolone?

Trenbolone began its life in the late 1960’s where it was studied extensively in France before being manufactured in the UK. The first form available on the market was the acetate ester under the brand name ‘Finaject’ and was sold and used in both the UK and France. It was originally a prescription drug primarily used to treat wasting diseases. Its use, however, was short-lived and it was soon discontinued despite a brief  re-emergence in the the early 1990’s under the ‘Parabolan’ brand.  Although it was removed from the human market many years ago it is still used across the globe by famers and vets to increase muscle mass gains in cattle (being sold for meat consumption).

Trenbolone is an extremely popular and well-know injectable anabolic steroids, with a potency that far exceeds testosterone and most other steroids available on the market today. The potential for both muscle gain and fat loss is immense, however with that comes the possibility of side effects. Whilst Trenbolone is known for inducing certain side effects, it is certainly not as potent as some people will tell you. That being said, it is certainly not a beginner steroid and only those with many cycle under their belt should consider using it.

Trenbolone, like Deca Durabolin, is a derivative of 19-nortestosterone as it has an alteration at the 19th carbon of its structure. However, unlike Nandrolone, its structure has been further changed to make it even more potent, and binds to the androgen receptor at a far greater rate than both Nandrolone and testosterone. Due to this it has an anabolic and androgenic rating of 500:500, which is 5 times that of testosterone. This clearly makes it an extremely potent anabolic steroids that is capable of producing exceptional lean muscle mass gains with little to no fat gain. Its potency is further enhanced by its ability to increase IGF-1 production – a hormone well known for increasing muscle mass. Fat gain and water retention are highly unlikely due to that fact that Tren does not capable of converting to estrogen.

In today’s market there are three forms (esters) of Tren available to users: Enanthate, Acetate and Hexahydrobenzylcarbonate. The former two are the most widely available esters, with the latter somewhat of a mystical novelty that only appears in very few steroid stores due to the fact that not many steroid manufacturers make it.

What are the side effects of Trenbolone?

Trenbolone is often referred to as being the most potent steroid commonly available on the black market today. Its reputation is such that many people will now refuse to take it for the fear of suffering major side effects. Whilst (serious) side effects are possible when taking it, the reputation it currently has is a little far-fetched. Due to the fact it does no convert to estrogen , users will not suffer from typical estrogenic side effects. On the flip side, however, it is an extremely potent androgen and as androgenicity increases so does the chance of encountering side effects. Most of the side effects that could occur when using Trenbolone are that which you would expect with any other anabolic steroids, however it does have two very unique negative effects that seem to be prevalent in most users, namely insomnia and excessive sweating (particularly at night), two things that can significantly impact upon training, diet and ultimately gains.

Androgenic side effects: Being so androgenic (Trenbolone binds to the androgen receptor with the same strength as DHT), many side effects can manifest themselves during usage. These include, but are not limited to: acne, oily skins, hair growth (face and body), hair loss (head) and aggression. Those worried about hair loss should not use it as products like finasteride will not stop hair loss when using Trenbolone (because it is not a substrate for the 5-AR enzyme).

Progesterone-related side effects: What most people aren’t aware of is the fact that Trenbolone is actually a progestin and therefore binds to the progesterone receptor (of around 55% of the strength of progesterone itself). For these reasons it can induce progesterone-related side effects. What are these effects? They are very similar to estrogen-related side effects, e.g. gynecomastia, bloating and water retention. To counter such effects it is advisable to have anti-estrogens (such as Arimidex), anti-prolactin drugs (such as Cabergoline) and vitamin B6 on hand throughout the cycle.

Trenbolone will of course should down the HPTA at a rate three times that of testosterone, so a strong PCT will be required. Another notable side effect of Trenbolone is its impact upon the cardiovascular system, so those who partake in sports that require their cardio levels to be in prime condition should think carefully before taking this exceptionally potent anabolic steroids.

Trenbolone Enanthate or Acetate?

This is one of the most often asked questions when it comes to Tren. In reality, it all depends on what you are it using for, how long you are using it for and what your experience of anabolic steroid usage is. Before we delve into these issues, let us have a brief look at the difference between the enanthate and acetate esters. There are two major differences – enanthate is a longer-acting ester with less mg of trenbolone per ml of oil, whereas acetate is fasting acting with more mg of trenbolone per ml of oil. 100mg of enanthate has around 70mg of active compound, in contrast to acetate that has around 80mg of active steroid. The former has a half-life of 7-8 days, the latter a half-life as 2-3 days. They both have their positives and negatives.

Enanthate advantages: Less frequent injections required. Users can inject once per week if they aren’t a fan of needles and/or injecting themselves.

Enanthate disadvantages: Stays in the system longer, therefore is any side effects are experienced then it will take long for them to leave the system.

Acetate advantages: Due to its short-acting nature, if the user experiences any side effects they will quickly stop within a few days.

Acetate disadvantages: More frequent injections are required – every day or every other day.

Those new to using my want to use the shorter-acting ester as if they do suffer from any serious side-effects them these will quickly. stop. However, acetate does come with the potential for ‘tren cough’, which can be very uncomfortable and may put off users from using it every again. For longer cycles the longer-acting ester is advised.

What dosage should I take for my Trenbolone cycle?

Just like any steroid, how much you take depends on three things, and Trenbolone dosage is no different. These three things are: steroid experience, bodyweight/size and goals. It goes without saying that novices and/or those with lower bodyweight should take less than those larger and/or more experienced. Cycle length must also be taken into consideration. What must be noted is that due its potency, Tren does not need to be taken in great amounts. Below we have listed the suggested dosages:

Novice: 100mg – 200mg per week.

Intermediate: 150mg – 300mg per week

Advanced: 300 – 500mg per week.

Going higher would certainly increase gains, but the law of diminishing returns would come into play, as well as some serious side effects.

What does a beginner Tren cycle look like?

Most will advise against a beginner or novice using Trenbolone, however in the conjunction with the right steroids and precautions there is no harm in doing so. When using Trenbolone for the first time users should start with a low dose, around the 100mg to 150mg per of acetate or 125mg to 175mg per week for enanthate – never any more than this. Trenbolone is commonly cycled with testosterone and that is highly recommended at all times. Despite there being much advice saying that users should employ a 2:1 testosterone to Trenbolone ratio, from anecdotal evidence it appears that this cause more side effects than a 1:1 or even 1:2 ratio. Personally, I would start out with a 1:1 ratio and see how you feel on that. If you start to experience side effects then lower the Tren dose and re-evaluate.

What other steroids can I stack Trenbolone with?

Due to it’s versatility, Trenbolone can be stacked with pretty much any other steroid. As it can be used for bulking, cutting and strength purposes it can be combined with any other anabolics that suit the users goals. It is most commonly stacked with various testosterone esters, however it is almost always stacked with Masteron nowadays due to the fact that Drostanolone appears to help combat the mental and libido-decreasing side effects that Trenbolone induces. Many labs are bringing out ‘TTM’ (testosterone, Trenbolone, Masteron) mixes in both short and long-estered versions. Other injectables that Tren can be stacked with are Equipoise and Dihydroboldenone. You may have noticed that Deca Durabolin isn’t on that list, and that is for good reason – mixing two 19-nors together can cause serious mental and libido based side effects that can take a long time to recover from. Orals choices will depend on the users goals, but Dianabol and Anadrol couple well with Trenbolone for bulking and Anavar and Winstrol go well with it for cutting.

What is the price of Trenbolone?

Trenbolone is actually fairly cheap compared to some of the more more expensive steroids like Oxandrolone, Primobolan and Halotestin, yet it is will cost more than the likes of testosterone and Deca Durabolin. A 10ml vial of enanthate ester will cost around $70-90 depending on the concentration (usually 200mg/ml), whereas acetate will set you back just $60-70, with the typical concentration being 100mg/ml.

What can you expect from Trenbolone?

With all the hype around Trenbolone it’s not surprising that many people don’t know what to expect in terms of both results and side effects. The answer to this question is completely subjective. Whilst most will gain very well on it, the degree to which side effects manifest themselves varies wildly. Some may experience some mild insomnia and night sweats, whereas other may suffer extreme mental sides effects such as aggression, anxiety and paranoia.

Gains wise, you can expect significant lean muscle mass gains and either fat loss or zero fat gained depending on your diet. A high card/low fat diet is best on Trenbolone as it vastly inhibits the mechanism by which carbohydrates are converted to fat and then stored.
