Nandrolone Results
Nandrolone is a synthetic anabolic steroid that bears similarity in chemical appearance to testosterone. The only major difference between the two molecules is a single methyl group . Similar to testosterone, nandrolone is administered via intramuscular (IM) injection and has a plasma half-life of approximately 8 days . Nandrolone binds to androgen receptors with a greater binding affinity than testosterone and with an increased anabolic, or myotrophic, activity rate (versus androgenic activity). For example and to assist in comparison, the myotrophic:androgenic ratio can be used to compare testosterone (~1:1) to nandrolone (~11:1) with regards to the ability to stimulate muscle growth compared to virilization.
Nandrolone half life and Dosage
Nandrolone esters are well absorbed from intramuscular sites with an absorption half-life of about 6-7 days.
The chemical nature of the ester influences absorption rate and peak plasma concentrations, higher peak plasma concentrations (30 nM) being achieved after the phenpropionate compared with the decanoate (14 nM).
Plasma concentrations of nandrolone relate well to biological effects in terms of endocrine parameters.
Nandrolone itself, like testosterone, is well absorbed from the gastro-intestinal tract but rapidly inactivated in the liver.
Its main metabolites are 19-norandrosterone and 19-noretiocholanolone.
Nandrolone Effect
The main male sex hormone testosterone has well-known anabolic actions, and this property is retained in synthetic derivatives such as nandrolone (19-nortestosterone).
Synthetic, 17-alpha-alkylated compounds (oxymetholone, stanozolol, oxandrolone, danazol) are orally active and, in animals, show selectivity for anabolic versus classic androgenic activity, although the evidence for such selectivity in the human is unclear.
These agents are/have been used for their anabolic properties in several disease states, including anemia, post-menopausal osteoporosis, hereditary angioneurotic edema and AIDS-related wasting myopathy.
