just because it doesn't aromatize doesn't guarantee you won't have issue... the likelihood is a lot less but its never a guarantee... im the type, that no matter what im running, i will use an ai... i don't overdo it but i always use it because i feel its always better to be preventative... there is a misconception that an ai will hinder gains... it definitely can if its misused but if its used properly, there can be a lot of benefit... forma is a great run with a cycle because it has many qualities to it... check out mrsupps and get yourself some forma bro...
