Nandrolone Cypionate (Nandrolone)

Nandrolone Cypionate

Nandrolone

Nandrolone is a modification of testosterone (carbon atom removed from the 19th position) With an Anabolic/Androgenic ratio: 125:37, meaning it is highly anabolic (muscle building) and moderately androgenic (male characteristics). Due to nandrolones chemical structure it only aromatizes (converts to estrogen) slightly, at about 20% the rate of testosterone when it interacts with the aromatase enzyme. Ergo, estrogenic effects are not a major concern with its use. Of note, however, is that nandrolone is a progestin with a binding affinity of 20% to the progesterone receptor (15) (PgR), so side effects are still possible, though rare.
