Deca 300 is one of the most powerful anabolic steroids. It promotes muscle growth, strengthening of bones, oxygen saturation of blood.
Deca 300 (Deca Durabolin) is simply a name given to a form of the drug which provides a 300 mg dosage in each ml of oil-based solution. It is usually preferred by aesthetically-focused athletes and other sportsmen.
Deca 300 (Nandrolone Decanoate) 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.
Deca 300 is usually used in bulking cycles, and also in cutting cycle to protect them from losing muscle mass and 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.
