Thanks. In the meantime I found some good explanations of why what yuz guys are saying is true about suppression and low dose test, which presumably would be the same for Orals too.
If this is the case, then what's up with these herbal test boosters? If they work, then they slightly raise T, which would have this same suppression with little benefit problem.
I know some of you say, I know! That's why I go aas. But others of you take these and some sell them.
Can anyone explain to me why herbals that raise T a bit (assuming some do) would not be counterproductive to take stand alone rather than Ptc?
It depends on the test booster. UNLEASHED lowers SHBH which in turn increases the bioavailability of the test you already have in your system. So more T is active but there isn;t any exogenous T added, so, there's no suppression.
