Dược Động Học :
▧ Absorption :
The absorption after oral dosing is rapid for testosterone and probably for other anabolic steroids, but there is extensive first-pass hepatic metabolism for all anabolic steroids except those that are substituted at the 17-alpha position. The rate of absorption from subcutaneous or intramuscular depots depends on the product and its formulation. Absorption is slow for the lipid-soluble esters such as the cypionate or enanthate, and for oily suspensions.
▧ Protein binding :
▧ Metabolism :
Nandrolone is unusual in that unlike most anabolic steroids, it is not broken down into the more reactive DHT by the enzyme 5α-reductase, but rather into a less effective product known as Dihydronandrolone.
▧ Half Life :
The elimination half-life from plasma is very short.
