Deca 300 is one of the most powerful anabolic steroids. It promotes muscle growth, strengthening of bones and oxygen saturation of the blood.

The 300 part of the name is simply given to a form of the drug which provides a 300mg dosage in each ml of oil-based solution. It is usually preferred by aesthetically focused athletes and other sportsmen.

It doesn't undergo the usual metabolism to Dihydrotestosterone that other substances do, it is converted to a similar, but far less potent form of Dihydronandrolone (DHN), which exhibits far less Androgen related effects on the body.

Usually used in bulking cycles, and also in cutting cycles to protect the user from losing muscle mass and obtaining achy joints due to strict diet. The Decanoate delivery agent attached to the active substance also makes it one of the longest lasting substances available, as the half-life of the chemical is around 3-4 weeks.
