Trenbolone is an anabolic steroid that is generally used by athletes to boost their athletic performance. The product is used to help men gain strength and build new muscle, particularly as they begin to get older and their physique becomes harder to maintain.
The product was initially developed as a way to increase muscle growth and appetite in livestock in order to make them bigger, thereby providing more meat. It was later used by bodybuilders as a method of building and maintaining new muscle.
