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. Veterinary Uses 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. Medical Uses There are no indicated medical uses of trenbolone acetate. The FDA has not approved this drug for use. 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 75 to 100 mg daily.
