I wouldn't buy it...I have seen opinions that the peptide is much too large to be absorbed orally, across the mucous membrane. May or may not be true...but I don't know of any doctors prescribing oral HCG. I don't think legit pharma-grade oral HCG even exists. There's a pretty big market for it as a fertility drug, and nobody likes giving themselves shots (OK, maybe a few people do) so if an oral form were possible I would think it'd be out there by now...stands to reason.
Most of the time you see the oral stuff, it is in "homeopathic dilution" for the HCG diet fad, which is to say there's a fraction of a percent (or none at all) of the peptide present. But when people miraculously lose weight on the stuff (oh, and by the way, a 500-calorie diet) they will swear by it!!! My suspicion is that most of these snake oils don't contain any at all, since it would be an illegal sale of a prescription drug...FDA has stated that it doesn't care about the dilution.
In any case, what are the supposed side effects or risks at the doses we use (250iu 2-3x/wk)? I have had nothing but positives since I added HCG to my TRT regimen...it's good stuff and I consider it essential.
From my understanding there is no benefit to using more than the usual dose...and possibly some harm, as you could desensitize the Leydig cells and that will impact your natural production ability in the future. The only point of HCG is to keep the testes functioning while you're taking exogenous T, since it mimics the LH/FSH which are diminished or shut down by taking T.
