Anabolic/ Androgenic Ratio: 125:37



Dynabol, a.k.a. nandrolone cypionate, possesses a modified removal of the carbon atom from the 19th position, with an anabolic and androgenic ratio of 125:37, meaning it is highly anabolic (muscle building) and moderately androgenic (affecting male sex characteristics). Due to Dynabols chemical structure, its interaction with the aromatase enzyme causes only slight aromatization (testosterones conversion to estrogen), at about 20% the rate of synthetic testosterone, so estrogenic side effects are not a major concern with its use. However, Dynabol is a progestin so rare side effects are still possible, especially impotence if testosterone is not stacked with it.

Steroid Form

Dynabol is an oil-based solution for intramuscular injection. Manufactured as an Australian veterinary drug, it comes in 50 mg/ml doses, most often sold in 10 ml multi-dose vials. Nandrolone also comes in powder form, which can be converted as desired.


Indications/Purpose & Side Effects

For the Indications/Purpose & Side Effects of Dynabol see the Deca-Durabolin profile.


Additional Information

Dynabol is popularly home-brewed, from nandrolone powder out of China, and is very popular in Australia, but rarely found.


Dynabol stacks perfectly with variety of potent traditional mass building compounds which traditionally include testosterones like cypionate, propionate, and enanthate. Dynabol also makes a solid contribution to definition cycles often comprised of such compounds as Primobolan, Winstrol, Oral Turinabol, Trenbolone, and Oxandrolone.
