For decades BB’rs have been using HCG both on-cycle and off-cycle to prevent testicular atrophy, as well as help re-grow the testes prior to commencing PCT. HCG, known as Human Chorionic Gonadotropin, accomplishes this function by mimicking the actions of LH (leutinizing hormone) within the body, which is the hormone responsible for stimulating testosterone production. Aside from the obvious cosmetic benefits associated with testicular maintenance, retaining function of the testes helps set the stage for a more rapid post-cycle recovery by retaining the organ’s ability to respond optimally to circulating LH.
While restoring testosterone production is an important step towards restoration of the HPTA, it is in only one aspect of total recovery. In addition to testosterone, the testes are also responsible for the production of sperm. In the same way that AAS suppress LH release, they also suppress FSH; the hormone necessary for sperm production. The bad news is that HCG doesn’t do anything for sperm count or motility. Its only function is to increase testosterone levels. Because of this, many BB’rs suffer from fertility issues.
Enter HMG (human menopausal gonadotropin). Unlike HCG, HMG has the distinct ability to normalize/maintain both testosterone and sperm production simultaneously. More so, HMG does not rely on mimetics in order to achieve the desired result. Rather, it promotes production through natural means. HMG is a combination of 2 pituitary hormones known as LH and FSH. LH, which was mentioned above, is the hormone which simulates testosterone production, while FSH (follicle stimulating hormone) is the primary hormone responsible for the manufacture of sperm. Both hormones must be present in order to retain full functioning of the testicles.
Looking at this information, it is hard to argue HMG’s superiority to HCG as a recovery/maintenance agent. After all, HCG only provides a partial recovery and it does so through un-natural means. HMG can be employed with good effect at anytime, but like HCG, it should be discontinued prior to starting PCT (Clomid,Nolvadex, etc), as the continued presence of exogenous LH & FSH will have a negative impact on the endogenous production of these hormones.
While this drug is still new, its popularity is rapidly increasing and I am confident that within the next few years, it will replace HCG as the recovery/maintenance product of choice. In conclusion, if you are looking for a more comprehensive recovery than what HCG can provide, you might want to consider trying HMG your next time around. For those specifically interested infertility, it is a no-brainer.
