Do you feel this a better product? I don't know much about it. I'm going to research it. Thanks for the reply.
7oxo and 7oh are cortisol inhibitors, they're good for PCT for this reason:
During the time you're on PHs/AAS/PS, the elevated steroid hormone levels means that there is a much greater probability that these hormones will bind with the cortisol receptors, since they do have an affinity for them, therefore, the body will upregulate receptors to compensate for the lack of cort bindings. So, when the steroid hormone levels drop, there will be more cort receptors that normal, thereby increasing the bindings (of cortisol) by a lot and increasing fat levels as a result. So, the 7-OH and the 7-oxo will inhibit cort, so you don't pack on the fat...eventually the receptors will be downregulated again, that's why people usually take the 7-oh / oxo for about a month afterward.
They don't, as far as I know anyway, aid in the rejuvination of the HPTA and help increase natural test levels/production.
