I've used it many times and love it. I honestly prefer OTC supps combined with HCG during PCT. Clomid makes me want to cry at the latest abandoned animal commercials and Nolvadex doesn't do a lot either. DAA, tribulus, maca, dhea, etc. I can actually feel, in particular the DAA. Now, you won't hold onto a huge amount of muscle and strength during any PCT, BUT I actually feel mentally normal fairly quickly on these items. And my libido comes back pretty quickly as well. Thats one thing in particular I noticed with the DAA, libido came back much faster than normal. I'd say DAA is one supp that definitely has a place in the arsenal.
