Clomid or Clomiphene Citrate is a selective estrogen receptor modulator (SERM), so it’s in the same grouping as tamoxifen (Nolvadex). It is the most widely prescribed drug for ovulation induction, which is useful for those who are infertile.It's key role is of an anti-estrogen. It not only curtails the effects of estrogen in the body, but also is used to slow catabolism after a steroid cycle.Clomid, as does Nolvadex, occupies the binding sites of estrogen receptors of cells, without activating the receptors. That reduces the extent to which estradiol can activate these receptors. In the case of the hypothalamus, this leads to the hypothalamus “concluding” that estrogen levels are low. If androgen levels are not elevated, as indeed they should not be after an anabolic steroid cycle, the hypothalamus is then stimulated to produce LHRH. This will act to increase LH and restart natural testosterone production.Normally, Clomid helps in sustaining the required and normal level of testosterone within 10-14 days of its intake.Clomid can and usually should be used as the only SERM in PCT. In most instances, there is no point to combining with another SERM. Where a second SERM such as Nolvadex is combined with Clomid, each should be used at half dose rather than full dose. Using full dose of each does not provide enhanced efficacy and only increases risk of side effects.Usage: 50-100 mg per day (1 -2 tablets) are sufficient. Most athletes use each morning and evening (after a meal) a 50 mg tablet, after the fifth day only a dosage of 50 mg per day.Period: 14 days
