Ecdysterone was tested in another study performed in 1986 by Smetanin. For this research, 117 highly trained speed skaters between the ages of 18 and 28 were tested for work capacity, body weight, lung capacity and VO 2 max. The results speak for themselves: all of the said parameters increased as well as an increase in the O 2 pulse max and an increase in the exhalation of CO 2 . Basically, they received more oxygen to their cells! This equates to decreasing recovery time, maximizing performance, permitting optimal muscle anabolism and maximum fat reduction. It also means the athletes using ecdysterone compared to those on a placebo experienced increased stamina, endurance and energy.
The oral bioavailability of oxandrolone is 97%.  Its plasma protein binding is 94 to 97%.  The drug is metabolized primarily by the kidneys and to a lesser extent by the liver .   Oxandrolone is the only AAS that is not primarily or extensively metabolized by the liver, and this is thought to be related to its diminished hepatotoxicity relative to other AAS.   Its elimination half-life is reported as to hours but is extended to hours in the elderly.   Approximately 28% of an oral dose of oxandrolone is eliminated unchanged in the urine and 3% is excreted in the feces .
