Ok so Nolva does nothing for estrogen control, it directly attaches it self to the Estrogen receptors in the breast tissue. This is a wonderful drug if your battling gyno issues. Now when it comes to AI your 2 main supps are Adex and Aromasin. Stay away from Letro, very harsh and only reason to use is a week out before a shoot or stepping on stage. Aromasin is a suicidal inhibitor so the estro you basically kill, then you have Adex which in turns blocks the estrogen receptors, safer? Yes and no, you can run into estrogen rebound effects off Adex but if you tank estro it’s a much quicker recovery timeframe. Aromasin is great if you know your body and how you respond, no rebound effect, but if you tank estro you.have a much longer road to recovery. Just to throw this out there please don’t think if you tanked estro on Aromasin you can just pop some dbols or pin TNE, nope it don’t work that way, the only road to quicker recovery of tanked estro is GH my friend. Not bro science real life testamonial. Bottom line brotha get bloods done before you start popping pills left and right because the next man said so.
