HCG
HCG is a unique drug used by male bodybuilders because of the fact that it can mimic the hormone LH (luteninizing hormone) in the body. LH is the hormone that is responsible for making testosterone in the testicles. Bodybuilders use HCG during long cycles due to the fact that after sometime on testosterone mimicking hormones the testicles will stop producing testosterone due to the use of a synthetic testosterone-mimicking drug.
HCG has significant applications to the steroid using bodybuilder due to the fact that it can help bring testosterone levels back to normal levels. This is where many will opt to employ HCG for the last 3-4 weeks of a steroid cycle.
A very important fact to note is that while using HCG you must use a drug such as Nolvadex or Clomid, and one of these (preferably both) should be used for the 2-3 weeks after using HCG, or you could end up where you started with low testosterone levels once again.
Another important aspect to note is that HCG should not be used for more than a 3-4 week period and it
should also not be used at very high doses, because this could desensitize the testicles to LH, and could leave you back in a bad position.
Typically HCG is used for the 3-4 weeks towards the end of a long cycle of steroids to raise natural testosterone levels in the testicles. HCG should be administered every 5 days to every 3 days (if you opt to use it more frequently doses should be adjusted accordingly) with the first shot in the last week of your cycle.
If you opt to go every five days the first two shots should be around 3000 IU, then the second two should be 1500 IU. It would be very wise to use Nolvadex during this time, and Clomid should be using following the HCG for 2-3 weeks along with the Nolvadex.
when i have used it, i took 1500-2500iu on the 1st/5th day of PCT
