HCG 5000iu itself could technically be considered synthetic LH (Luteinizing Hormone) and FSH (Follicle Stimulating Hormone), but the truth is that HCG is indeed a different hormone, but in men it will mimic the actions of LH and FSH identically. LH and FSH are gonadotropins manufactured and secreted by the pituitary gland, and these two hormones in men signal the Leydig cells in the testes to begin or increase the manufacture of Testosterone. The term ‘gonadotropin’ refers to any compound or hormone that stimulates the gonadal organs (testes in men, ovaries in females). In females, LH and FSH trigger ovulation (the manufacture of eggs in the ovaries). HCG, because it is essentially a mimic of LH and FSH in terms of its physiological activity, is administered medically to females that suffer from infertility (perhaps because they do not endogenously manufacture sufficient levels of gonadotropins as it is or for other reasons). Within medicine, HCG is also administered to males for the treatment of hypogonadism (deficient androgen production). It is also used medically for the treatment of pubertal delay in adolescent males, as well as prepubertal cryptorchidism, which is a condition in which an individual’s testicles have improperly descended (either during or after puberty). Among the anabolic steroid using bodybuilders and athletes, HCG has been utilized for a long time for its ability to restore endogenous Testosterone production following the termination of an anabolic steroid cycle. This is a period in which hormonal restoration is imperative, and HCG is normally inserted into a multi-compound protocol of approximately 4 – 6 weeks after an anabolic steroid cycle has ended, and this is known as PCT (Post Cycle Therapy).
Specifically, it is found in very high concentrations in pregnant females as previously stated. HCG is in fact what is used as the number one primary indication of pregnancy in females, as it is only present in very, very high quantities in females during pregnancy. HCG is what the home pregnancy tests detect in urine, and if present in significant quantities, the home pregnancy tests will turn blue. In women who are pregnant, HCG 5000iu increases in the body rise very rapidly, and can be detected within 7 days of increased secretion in the body. At this time period, however, HCG levels are only beginning to rise, and blood plasma levels of HCG do not actually peak until approximately 2 – 3 months into pregnancy.
