just to drive the point home, recovery from Andro's is not the same as recovering from say a designer steroid cycle. the pulsatile nature of bodily enzymes and all else going on, these DHEAs can and do convert, but, and here's the catch, they don't convert at high rates, nor do they last long in the body. so, if we use something like DHEA analogs and ingest it, some of it makes it through the gut. whatever amount of Andro's that makes it into the bloodstream is only active to make conversion for about an hour and a half (+/- depending on which). so, you have that time window to make the needed conversion[s] to the target hormone. again, this ultimately reduces further that amount of hormone you are trying to get to. that said, we have what you would consider a micro amount of all naturally produced target hormone. no esters attached. no methyl's prolonging the half-life, and the possibility to back convert to the original Andro makes this a totally different outcome and likewise approach to recovery.
[ I want to also point out that I am not mentioning the other effects of intermediate conversions or active stance of the PHs on purpose, though it should be mentioned that many Andros' exhibit an effect prior to converting to other hormones]
It's my stance that most people can recover with a healthy HPTA in a week or two without lasting effects on the endocrine system. do you need a SERm??? I doubt it but we are individuals so maybe you do. do you need a test booster? again maybe... maybe not. I think most people can follow a time-on-time off approach to cycling Andro's, and with good nutrition and training, make a recovery without a pct.
Where is the fun with that? Using Apex's Test boosting/hormonal optimizing/estrogen limiting/cortisol managing arsenal Virtually ensures a successful recovery and little chance of any kind of rebound.
