Chemical Structure: 17β-Hydroxyestra-4,9,11-trien-3-one
Delivery Method: Injectable
Half Life: Ester dependant:
•Trenbolone Acetate ~1 day
•Trenbolone Enanthate, Hexahydrobenzlycarbonate, Cyclohexylmethylcarbonate - 5-6 days
Background
Trenbolone is a very powerful steroid that has never been FDA approved for use in humans. It was originally developed as finaplex pellets for use as a vetinary product to be put under the skin of cattle. However over time bodybuilders have realised its unique properties and powerful benefits and it has become a favourite anabolic steroid for many, despite having more harsh side effects than most other steroids. Many people would convert the pellets into an injectable form, in a rather crude and dangerous manner that would neither be safe nor sterile, and poses many risks. However, despite being non-approved by the FDA, there are a number of respectable Underground Labs (UGLs) that produce quality injectable forms of trenbolone. For the user who understandably likes to stick to pharmaceutical grade steroids, unfortunately there is no such form of trenbolone available.
Trenbolone is a highly androgenic steroid, with binding to the Androgen Receptor (AR) in the region of three times as high as testosterone. It does not aromatise and so is not subject to estrogenic side effects. In addition to high androgenicity, it is also extremely anabolic too, thus is very good at building muscle mass, and retaining muscle mass in a calorie deficient mode. It is also thought that trenbolone inhibits cortisol production directly through the glucocorticoid receptors. Trenbolone is often found to be a body transforming drug, and also can aid a little in fat loss. This may be due to the very strong binding of trenbolone to the AR, which has been postulated to be one mechanism that results in the activation of fat loss pathways, possible through direct binding to fat cells' ARs. This makes trenbolone a favourite among bodybuilders for cutting, and in addition to these benefits, trenbolone usually results in large increases in strength due to its high androgenic effects.
Trenbolone although not converted to estrogen, does have progesteronic effects, which will be discussed further in the side effects section of this article.
Suggested Cycles / Uses
Typically today underground labs produce trenbolone acetate as 75g/ml or 100mg/ml. It is often recommended first-time users of trenbolone to use the faster acting acetate in case the side effects become too much for the user, they can then come off of the steroid very quickly and it is out of the system much quicker than, for example, the enanthate ester. For the novice user, 75mg or 100mg every other day (eod) is advised, however due to the acetate ester being even shorter than a propionate ester and the half life 1 day or less, to both reduce sides and aid gains, it is advisable that the user (if they can bear every day injections) injects trenbolone acetate every day (ed), at 37.5-50mg ed.
More advanced users may find that taking the trenbolone to amounts over 500mg per week has very desirable effects on strength and body composition, however note that the side effects will also increase with the increase in dose. Due to the negative effect that trenbolone has on libido, it is not generally recommended to take trenbolone without testosterone. However, one can take trenbolone for short periods without testosterone and introduce an aid such as Proviron (metsterolone) to help with the libido issues, along with proper extensive post cycle therapy (PCT) for recovery. A typical test-free cycle with trenbolone may include something like 600mg Primobolan per week, 400mg trenbolone enanthate per week, for 10 weeks, PCT starting 2 weeks after last injections. The enanthate ester and other similar esters of trenbolone can be injected twice per week.
