Does Methadrol exetreme cause estrogen related side effects? I got a few bottles and haven't used them yet but it seems its the same as super dmz(old formula) with 5 more mgs a pill of superdrol and has deca drol which supposesively doesn't convert to estrogen. I wouldn't think it would be an issue but figured I'd ask anyway. I'm gonna run an 8 week cycle of test e 750mgs and 375 mgs of deca both weekly. Than 2 methadrol pills daily the last weeks 5-8.
