I too have utilized 1-AD with good results. A question to Scientist though. If 1-AD offers the precursors and stimulus to testosterone production, why would it decrease the bodies ability to produce the big T after the cycle? Isn't it just offering some raw materials towards production? It seems that the T-engine would be just fine afterwards. But I'm probably wrong, hell I got married once. I've always wondered about this with these products.
This is not a challenge, just a newbie seeking enlightenment.
