Finaplex (also known as trenbolone) is a synthetic steroid which was once used in the agriculture industry to fatten livestock. The drug is a potent weight stimulant agent and can increase the appetite. Finaplex is an esterified steroid which enables it to act for a longer period of time. Even though it was used as an anabolic agent, it is also a potent androgenic drug. It is only available as an intramuscular injection. As soon as it was realized that the drug had anabolic properties, the bodybuilders and other athletes started to consume it in large amounts. The drug does increase the body weight and muscle mass as long as the diet is rich in calories.
