COMBO-MED (Deca-Durabolin, Retabolil) is an anabolic and androgenic steroid produced in the form of injections. The chemical name is 19-nortestosterone. The human body can produce nandrolone in response to heavy and prolonged physical exertion (and during pregnancy in women). At the same time, its concentration is very small, and is only a few nanograms per milliliter of urine. Nandrolone is available in the form of decanoate and phenylpropionate (Nandrolone Decaonate and Phenylpropionate). The steroid was first introduced in the market in 1962, and today it occupies a key position in the market of sports pharmacology. The popularity of the drug has brought its high anabolic activity with a low probability of side effects.

Its chemical name is decanaldehyde nandrolone due to the absence of the 19th position of the carbon atom. Thus, it has a progestin nature and an androgenic effect as compared with testosterone. After entering the body, Nandrolone is converted by the enzyme 5-alpha-reductase into dihydronandrolone (very weak androgen), and almost does not cause side effects. But lowering the libido on the course is not ruled out.
