              Just wondering what's the half life of Anadrol 50.

                What are the half-lives of different esters?

                Shorter chain esters have shorter half-lives, because of their lower partition coefficient. Testosterone cypionate has a half-life of 8 days5, the enanthate ester has a half-life of 4 days6, and nandrolone decanoate has a half-life of 8 days7. These figures are only approximate. The difference between these values for cypionate and enanthate probably includes difference attributable to different measuring techniques. The actual difference is probably not more than two days.

                In the rat, where half-lives of anabolic steroid esters are similar to those in humans but somewhat shorter, the half-lives of the phenylpropionate, decanoate, and laurate esters are 1, 5, and 10 days respectively.3 The same trend would be expected in man.

                Half-life is linearly related to log partition coefficient, which is itself linearly related to the carbon chain length, the exception being if the ester is an unusual one such as phenylpropionate. This was shown by James et al.3 for the formate through valerate esters of testosterone in the rat. The half-life of testosterone propionate was approximately 4 days, and each carbon added to or subtracted from that chain length changed half-life by about 1.5 days.










                why is this not the same as your half lives?


                another article saying 4 days as a half life for enanthate: http://books.google.ca/books?id=ZiZ7...um=4#PPA417,M1
