Pharmacodynamics Trenbolone acetate is a
prodrug of
trenbolone. This is based on a book by William Llewellyn but has not been definitively proven. Trenbolone was never approved for human use, and therefore limited data on the subject exists. The relevant literature, is usually done in rats, which makes the 500/100 potency number inaccurate. Rats respond differently to androgens and are less sensitive to androgens. While some literature report a 5 fold higher potency, two other scientific reviews report a 3 fold higher potency, which makes it unclear as to how large the relative potency actually is. Trenbolone is an
agonist of the
progesterone receptor (PR), and in relation to this, has moderate to strong
progestogenic activity. Similar to many other AAS, trenbolone acetate has the capability to produce
insulin-like growth factor-1 (IGF-1). Trenbolone acetate also has the ability to increase red blood cell count. With a larger amount of
red blood cells,
blood oxygenation is enhanced. This allows for enhanced
muscular endurance and therefore promotes a faster rate of recovery. Trenbolone acetate is capable of inhibiting
glucocorticoids such as
cortisol. The properties of glucocorticoid are the opposite of androgens as muscle tissue depletion and fat gain is promoted. Administration of trenbolone acetate aims at decreasing the production of
glucocorticoid hormones. Trenbolone acetate’s contribution to feed efficiency, also known as nutrient efficiency is what makes it an attractive AAS used for agricultural purposes. Food is one of the most
anabolic substances that any living organism can consume, and therefore with the administration of trenbolone acetate, every
nutrient in the body becomes a lot more valuable. This facilitates an organism's body that is exposed to the AAS to make better use of the nutrients already consumed.
Pharmacokinetics The
acetate ester of trenbolone acetate allows for slow release post injection. This ester gives trenbolone an activated
elimination half-life of about 3 days. ==Chemistry==
