im gyno prone....and i finally started using nolvadex during cycles..my cycle was 8 weeks long.....i was taking 10mgs of nolv ED....test prop 50 ED...winny 50 mgs for 6 weeks...and proviron throughout cycle....and for the first time my muscles were flat during the cycle....no crazy pumps like in the past...it was horrible.....I know nolva kills IGF-1 but I didnt know it was going to impact my gains that much! MY question is...should i take arimidex during the cycle INSTEAD of nolvadex because arimidex does not kill IGF-1 ??? what do you guys think??
