Trenbolone acetate is a steroid hormone developed for veterinary use. Although intended for cattle, it has been taken by humans and been used by athletes and bodybuilders. There are contraindications for both cows and humans as well as a variety of side effects for humans. It is illegal in the United States for anything other than veterinary use.
What Is It?
Trenbolone acetate is a pharmaceutical version of the steroid hormone trenbolone. It is a potent androgen, meaning it shows high affinity for bonding with the androgen receptors in muscle tissue. It is produced by a number of veterinary companies and sold under the brand names Finaplix-H, Finaject or Finajet. The addition of the acetate molecule increases its half-life in the bloodstream by making it more difficult for the liver to break down. Trenbolone increases muscle mass and appetite.
Trenbolone acetate is intended for use in beef cattle. Farmers use it to increase the cow's muscle mass and overall weight. Additionally, it makes the cow’s digestive use of feed more efficient.
Trenbolone acetate is administered via a special gun that injects pellets of trenbolone underneath the cow’s skin. It is injected shortly before slaughter to decrease the loss of muscle and weight during transportation to slaughterhouses.
There are no indicated medical uses of trenbolone acetate. The FDA has not approved this drug for use in humans.
Bodybuilding and Athletics
Trenbolone is used by bodybuilders seeking to gain lean muscle mass. Because it shows high affinity for the androgen receptors, it produces quick muscle gains with little additional water retention. It also stimulates the appetite while reducing body fat and decreasing catabolism (muscle loss) even while dieting. Users have reported increased strength gains as well. Bodybuilding dosages range from 50 to 100 mg daily.
In their 2006 book “Game of Shadows,” authors Mark Fainaru-Wada and Lance Williams alleged that Major League Baseball player Barry Bonds used trenbolone acetate.
Veal calves should not be injected with trenbolone acetate. Also, farmers should only inject trenbolone acetate into cattle intended for slaughter within nine weeks.
As a veterinary steroid, trenbolone acetate was not developed for and is not recommended for human use. Because it is an androgenic steroid, those who suffer from a number of conditions should avoid taking this drug. These include heart disease, prior cardiac arrest, liver damage, diabetes and prostate or breast carcinoma. Those taking blood thinners should avoid taking this drug.
Humans should not inject trenbolone acetate with the gun used to inject cattle, as this injection device will poke a pencil tip sized hole into the skin and muscle.
Illicit users of trenbolone acetate have reported a number of side effects. These include high blood pressure and insomnia, as well as marked aggression and an increased sex drive. Some users have experienced night sweats and coughing episodes.
Because trenbolone bonds to the androgen receptors, it also produces masculine characteristics. These include male-pattern baldness, acne, greasy skin, deeper voice, and increases in facial and body hair. Women are particularly susceptible to these masculinizing effects.
Trenbolone is only legal for veterinary use in the United States. It is currently listed as a Schedule III drug in the United States, and illegal possession, distribution or sale can carry a punishment of five years under Federal law.
Also, trenbolone has been banned by the International Olympic Committee, the NCAA and most professional sporting organizations. Those caught using trenbolone can face a suspension or ban.
