Researchers in Portugal have conducted a study on Oxandrolone’s metabolites when consumed with caffeine. The Portuguese researchers acting on behalf of a doping lab Laboratório de Análises de Dopagem consulted the literature.
Caffeine has been studied before about its ability to increase the uptake of certain drugs, notably Paracetamol in this study. So they curiously questioned if this effect would be evident in Oxandrolone (Anavar) users.
The Portuguese researchers gave 0.4mg of Oxandrolone to a subject who consumed three espressos per day. The caffeine content of one espresso is 64mg. For the next forty hours the subject was monitored for the amount of caffeine, Oxandrolone and the inactive Oxandrolone metabolite Epioxandrolone in their urine.
The experiment was then repeated giving the subject a larger caffeine dosage of 300mg in pill form. The figure above shows that the amount of Oxandrolone and Epioxandrolone rose by a factor of 20 and 15 respectively making its effects more pronounced.
The researchers concluded that their experiment may show that caffeine causes a considerable improvement in the uptake of Oxandrolone by the body. “Practically this means that similar concentrations/effects may be achieved using lower dosages”, they write. “Other anabolic steroids should also be investigated.”
