If theres a spike in estrogen then wouldnt there also be a spike in testosterone, I know people who do roids also get a spike in estrogen as well. Im no expert so I could be wrong.
Even if arnold dide lose testosterone, he injected more than he lost lol. Arnold was a fucking beast lol but look at micheal phelps. He smoked untill it became public and he had to quit and look at all his medals lol
