daa, pct assist, and an aromatase inhibitor (formestane, inhibit-e, erase), all increase testosterone, via different means.
7-spray, reduce xt, supress c, these are cortisol reducing compounds. cortisol is a catabolic (tears down larger molecules into smaller ones for energy) hormone. you want to keep your body in an anabolic state by keeping the anabolic hormones high, (androgens, hgh, etc) and the catabolic hormones low (cortisol, estrogen).
but, a lot of people dont know, or forget you want to control these hormones, not destroy them. you are trying to levelize your hpta, not keep it on the hormonal rollercoster you started with the supraphysiological dosages of modified androgens you were injesting.
dosages for ai's & cortisol reducers will vary person to person, it will take practice for you to find what dosage is best.
good luck bro. :thumbsup:
