Trenbolone acetate

Trenbolone acetate, sold under brand names such as Finajet and Finaplix among others, is an androgen and anabolic steroid (AAS) medication used in veterinary medicine, specifically to increase the profitability of livestock by promoting muscle growth in cattle. It is given by injection into muscle. Side effects of trenbolone acetate include symptoms of masculinization like acne, increased body hair growth, scalp hair loss, voice changes, and increased sexual desire. The drug is a synthetic androgen and anabolic steroid and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT). It has strong anabolic effects and highly androgenic effects, as well as potent progestogenic effects, and weak glucocorticoid effects. Trenbolone acetate is an androgen ester and a short-lasting prodrug of trenbolone in the body. Trenbolone acetate was discovered in 1963 and was introduced for veterinary use in the early 1970s. In addition to its veterinary use, trenbolone acetate is used to improve physique and performance, for which purpose it is purchased from black market suppliers. The drug is a controlled substance in many countries and so non-veterinary use is generally illicit.

Uses

Veterinary uses

In the livestock industry, trenbolone acetate is more often called Finaplix. It was intentionally developed to promote androgen and gain muscle mass in cattle. Due to its properties, this allows livestock to grow as much muscle as possible before they are transported to a slaughterhouse. Methyl cellulose and yellow dye are usually present in pellets given to livestock. A single dosage generally consists of ten pellets, and a package of Finaplix usually consists of one cartridge containing one hundred pellets. The medication is administered by subcutaneous injection into the posterior ear using an implanter gun. Finaplix is consistently implanted until the animal is ready to be slaughtered. There is no withholding period. Due to the common practice of trenbolone acetate use in veterinary medicine, it is quite common to find traces of trenbolone metabolites in cattle worldwide.

Non-medical uses

Bodybuilding Trenbolone acetate has never been approved for use in humans (but another ester of Trenbolone called Trenbolone hexahydrobenzylcarbonate was, for a short period of time under the name “Parabolan”, during the 1980's, up until its discontinuation in 1997.) therefore guidelines for human consumption do not exist. However, athletes and bodybuilders have been using trenbolone acetate as a physique- and performance-enhancing drug for decades. Some argue there are many benefits for bodybuilders using trenbolone acetate as an AAS. Unlike exogenous testosterone, trenbolone acetate does not cause fluid retention, so bodybuilders appear leaner; therefore, it is more commonly used during preparation for competitive events. Trenbolone acetate does not convert into an estrogenic metabolite; thus there are no estrogenic side effects. Trenbolone enanthate is a commonly used AAS and lasts much longer than trenbolone acetate with intramuscular injection.

Medical uses Trenbolone acetate was never approved for use in humans and hence has no medical uses. However, as an AAS, it would be expected to be effective for treating indications in which other AAS are useful, such as androgen deficiency, wasting syndromes, muscle atrophy, and certain types of anemia. Trenbolone hexahydrobenzylcarbonate was previously produced for human use by Negma Pharmaceuticals of France in 1.5 ml ampoules containing 76.5 mg of the steroid.

Side effects Trenbolone acetate, like any other AAS, has many side effects. Its strong androgenic properties stimulate virilization, making it unsuitable for women pursuing physique or performance enhancement. The side effects of trenbolone acetate are similar to other AAS; however, the negative side effects specific to trenbolone acetate are as follows:

Androgenic Trenbolone acetate has androgenic activity. Common side effects include oily skin, acne, seborrhea, increased facial or body hair growth, and accelerated scalp hair loss. Severity of these side effects varies based on an individual's genetics. Men susceptible to hair loss have a higher chance of becoming permanently bald. In women, voice deepening, hirsutism, clitoral enlargement, and general virilization may occur.

Hypogonadism Trenbolone acetate contributes greatly to development of muscle mass and feed efficiency; however, administration of any AAS suppresses natural testosterone production and therefore has the potential to cause hypogonadism.

Cardiovascular Administration of any AAS can lead to cardiovascular issues. Trenbolone acetate can have a strongly negative impact on cholesterol levels by suppressing high-density lipoprotein (HDL) cholesterol production and stimulating low-density lipoprotein (LDL) cholesterol production. When compared to oral AAS, trenbolone acetate exerts a stronger negative effect on cholesterol levels.

"Tren cough" The exact mechanisms underlying "tren cough" are not known; however, trenbolone acetate's androgenic effect activates a variety of lipid-like active compounds called prostaglandins, many of which are inflammatory and vasoconstrictive. Prostaglandins act on two signaling pathways: cyclooxygenase (COX) (also known as prostaglandin-endoperoxide synthase) and lipoxygenase (LOX) (EC 1.13.11.34, EC 1.13.11.33, etc.). The bradykinin peptide is well known to promote a cough reaction associated with ACE inhibitors prescribed for hypertension.

Estrogenic and progestogenic Trenbolone is not estrogenic; therefore, use does not lead to excess fluid retention. However, due to trenbolone's potent progestogenic activity (it binds with high affinity to the progesterone receptor), gynecomastia, characterized by development and swelling of breast tissue, may occur.
