Narcotic painkillers do lower testo, my endocrinologist notes it. This is prolly not going to be a issue for short term user.
Any number of combinations or diet or other body reactions could cause gyno on an identical cycle tahts
never been a problem in the past....
Thats why its smart to have a selection of Nolva, Adex, letro etc.
Adex + Nolva was a real favorite when Adex 1st hit the market, and it was God awefull expensive.
Before that there was only Nolva, and before that NOTHING.
