HCG Pregnyl 1500 IU - 3 amps

HCG (human chorionic gonadotropin) is provided as a glycoprotein powder to be diluted with water and taken by injection, either intramuscularly or subcutaneously. It acts in the body like luteinizing hormone (LH), stimulating the testes to produce testosterone even when natural LH is not present or is deficient. It therefore is useful for maintaining testosterone production and/or testicle size during a steroid cycle.

Additionally, outside of or in-between steroid cycles, it can be very useful for increasing testosterone production. The success of this depends on the ability of the testes to actually produce greater amounts of testosterone with increased stimulation. Where the testes themselves are the limiting factor, HCG cannot overcome this.

Including HCG as part of a hormone replacement therapy (HRT) program is superior to relying on testosterone alone if maintenance of sperm production and/or normal testicle size is considered important. Use of testosterone alone can result in infertility or reduced fertility, as normal testicular function depends on higher intratesticular testosterone levels than results from such use.

With regard to steroid usage, HCG should either not be used as part of post-cycle therapy (PCT) at all, or should be used only in a rather precise manner to avoid impeding recovery, shortly to be described.

Post-cycle recovery of LH production requires androgen levels to have fallen back into the physiological range. With use of medium or long-acting esters, this is a slow process. For example, let’s suppose that a given testosterone ester’s half-life is 7 days, and that 800 mg/week was used during the cycle. If so, then one week after the last injection, levels will be similar to what they would be if 400 mg had been taken weekly for some time, and with another 400 mg having just been injected. At the two week point after the last injection, levels will be commensurate with ongoing 200 mg/week use.

This is without using HCG during this period.

By this point, ordinarily some recovery could begin with use of Clomid or Nolvadex.

But if HCG were used during this time, or started at this point, testosterone levels would be similar not to those of ongoing 200 mg/week usage, but to that level plus another 100-200 mg/week of equivalent increase from HCG. This would interfere with recovery of LH production.

The better plan is, if using HCG, to employ it during a cycle to maintain testicular function so that the testes will be responsive to LH as soon as its production is restored. There will also be the advantages of maintaining testicle size and of providing some additional testosterone via HCG-stimulated production.

This last point will be of no great importance when a large amount of steroids is being used weekly, but can be quite significant if the total milligram amount is modest.
