thanks i appreciate the advise bro...i think what i have is just the active ingredient..methasterone 10mg per pill. it's none of the other things that sdrol has in it. so i think what u are talking about with the negatvie reaction to nolva is taking place in those other anti estrogens that are in the sdrol. either way i already bought it..im just gonna run it and see what happens. i was talking to who i bought it from and mentioned what u said and they said with this stuff because it's only the one ingredient it shouldn't be a prob. but i guess u never know...
