Profit! In all honesty most of the PH/DS that are strong enough to be ran by themselves effectively are going to require at least having a SERM on hand. At best these over the counter PCT products are good for andro & DHEA based products, not ran at an extremely high dose. These natty PCT products are basically a best effort to match the effects of prescription SERMS & AI's. However they are not as effective. Any time you completely shut yourself down you need a SERM. Any time you take just enough to slightly increase growth shut down will begin. Natty PCT will definitely speed up your recovery above not using anything. It will do so quite well, however that being said it is still not on par with a legitimate SERM as far as recovery goes. The more you gain on a cycle the more you stand to lose because you are also going to be more shut down. In order to keep the most gains the MOST efficient recovery method SHOULD be employed. However if the legality of that dicates that you are not willing then you settle for what the OTC stuff can do. Again it is a definite improvement over no PCT at all but not on par with a PCT using legit meds.
