Took them for 5 weeks at 30mg/day. Lost 9lbs(from 181) but did increase my training(judo/boxing) from 2x/week to 5-6x/week. Did have some joint pain but that might have been due to the increase in training so not sure about that. No sides at all that I can say. No pct either. 42 yrs old.
Since you had joint pain maybe they were winstroll tabs. It is known that some cie announce winstroll pills as anavar. People say they do work thinking they're anavar. Its only cheaper for them.
