The History of Trenbolone and Trenbolone Cycles

The History of Trenbolone:

The Trenbolone Hormone was first created by Hoechst-Roussel in the late 1960’s and the Acetate version would be sold under the names Finajet and Finaject. It was originally a veterinarian preparation, and used to enhance the muscle on cattle so they would yield higher beef production and become more valuable. This would be discontinued in the late 1980’s, but would be replaced by the development of Finaplix pellets, cattle implants to be punched behind the animal’s ear with a pellet gun. Creative bodybuilders used solvents and filters to extract the hormone from the pellets into a vial with injectable oil.

The Application of Trenbolone Acetate

Before After To increase its effective half-life, trenbolone is administered as an ester conjugate such as trenbolone acetate (Finaplix), Trenbolone enanthate, or Trenbolone Hexahydrobenzylcarbonate (Parabolan). Plasma lipases then cleave this ester attached to trenbolone, leaving free trenbolone in the bloodstream. Trenbolone acetate is the fastest acting ester of the three available forms, with an active half-life of about 48hours. Trenbolone hexahydrobenzylcarbonate is the next fastest acting ester with an active half-life of 5-7 days. Trenbolone enanthate is the longest acting ester with an active half-life of around 8 days. There is differing scientific conjecture regarding half-life of esters, so they are approximate. (Edited by Hongxipharm)

The important thing to understand, is that any ester of the same name for any compound will have the same half-life. So, Trenbolone acetate and testosterone acetate have the same half-life, and intuitively, trenbolone enanthate has the same half-life as testosterone enanthate. It is the ester that determines how long it takes your body to break it down, and hence, the half-life.   Trenbolone Acetate should be injected every other day give or take a day, while Trenbolone hexahydrobenzylcabonate and Trenbolone enanthate can be injected on a weekly basis.
Oral Metribolone (Methyltrienolone) Cycle:

Trenbolone Acetate Cycle: this cycle is with ED – every day – injections, but can be modified for EOD – every other day – injections:

Trenbolone Enanthate cycle – this cycle is mainly injectables without an oral kickstart:

Trenbolone Hexahydrobenzylcarbonate (Cyclohexylmethylcarbonate) cycle – also no oral kickstart:

Trenbolone has both anabolic (muscle growth) and androgenic (development of male characteristics) effects. Trenbolone has a binding affinity to the androgen receptor five times greater than that of testosterone. When it is said that trenbolone is 5 times more anabolic than testosterone, it is not that it is more anabolic in and of itself, it is just 5 times more readily available to bind to the androgen receptors. Trenbolone is a 19-nortestosterone anabolic androgenic steroid. It contains a structural change from testosterone, lacking a carbon atom at the 19^th position. This just means that it is in the same category as Nandrolone Decanoate (Deca Durabolin), and is simply a modified version of the Nandrolone hormone. There is a double bond in the structure at carbon 9 and 11, causing the metabolism to slow. This is the direct reason for the increased binding affinity making Trenbolone five times more potent than testosterone. This also inhibits aromatization. Therefore, you don’t see the estrogenic side effects with Trenbolone that you would see with testosterone such as water retention. You can see gynecomastia symptoms, but that is a mechanism of progesterone and will be discussed later.

Like many anabolic steroids, Trenbolone Acetate will increase protein synthesis and NO2 in the muscle tissue. This provides an atmosphere of enhanced anabolism, and gives way to the strong anti-catabolic nature of Trenbolone. For this reason, Trenbolone Acetate is supremely beneficial for pre-contest stacks. It is anti-catabolic during periods of caloric deficit, and promotes very little water retention. Like many anabolic steroids, Trenbolone Acetate will promote the release of Insulin-like Growth Factor-1 (IGF-1), a powerful highly important peptide for recovery and rejuvenation. As with other AAS, you can expect Trenbolone to increase red blood cell count, increasing blood oxygenation for enhanced endurance and rate of recovery.

You can also expect this compound to inhibit glucocorticoid hormones, stress hormones that catabolize muscle tissue and promote fat gain. Trenbolone’s strong binding affinity to the androgen has been directly linked to strong lipolysis, enhancing the body’s metabolism more than testosterone and burning fat at a higher rate.
