Product Description
HCG is a natural analog of LH, the pituitary-produced hormone which stimulates sex hormone production in the testes or ovaries. HCG binds and activates the same receptor as LH and is equally effective in stimulating testosterone production in men, or estrogen production in females.
This LH analog exists because it provides additional functions required in pregnancy which LH cannot support. These additional functions cannot occur in men and have no practical effect or consequence with regard to using HCG for improved testicular function, and so are omitted here.
Pharmaceutical HCG
HCG is typically isolated from the urine of pregnant women: the pharmaceutical process of course involves extensive purification. Despite this esoteric sourcing I know of no quality problems with any genuine pharmaceutical brands of HCG.
All or nearly all practical experience in bodybuilding is with this HCG type, which is generally sold in vials of lyophilized powder, typically at 5000 or 10,000 IU per vial.
HCG may also be produced by recombinant DNA technology, similar to modern hGH production. The Ovidrel brand is manufactured this way, and is available only in preloaded syringes.
Availability of recombinant HCG at best low at present and there is no performance advantage to be experienced from choosing this type.
A technical difference, which makes no difference for bodybuilding, exists between these types of HCG. Namely, recombinant HCG consists only of dimeric HCG with two types of subunits. In contrast, urine-sourced HCG, as with HCG found in the bloodstream during pregnancy, also includes the subunits themselves as monomers. Since it’s possible that with chronic use this could have an outcome difference, that aspect will be discussed, but later on.
