First off why dont you friking read about beastdrol and Diesel before anything....
You do not need NOLVA because : Do I need an AI (aromatase inhibitor) when using Beastdrol?
Typically, no you do not. Beastdrol will not convert to estrogen, and in fact it will do the opposite to estrogen levels. When doing PCT, it is always wise to have one handy just in case. But I have yet to hear of someone needing an AI with Beastdrol.
Will taking Beastdrol give me gyno?
No, it will not.
