HCG (Human Chorionic Gonadotropin - human chorionic gonadotropin) is a hormone found in the female body during early pregnancy (occurs in the placenta). It is in fact the pregnancy indicator measured by pregnancy test kits (pun intended), and because its origin is not found in the body at any time in those quantities. The levels of this hormone in the blood will become noticeable in just seven days after ovulation. The level will rise evenly, reaching a peak about two to three months of pregnancy. After this point, the level of the hormone drop gradually until the moment of birth.

Like any prescription drug, HCG offers us some interesting benefits. In the United States, there are two popular brands, Pregnyl, Organon, and Profasi, Serono. These drugs are approved by the FDA (Federal Drug Administration) for the treatment of undescended testicles in young boys, hypogonadism (underproduction of GnRH - gonadotropin) and as a fertility drug used to help induce ovulation in women . When this compound was prepared as a medical item, the hormone was human origin. Because often there is fear in terms of products of biological origin, there is little research with regard to pathogen or sterility problems with HCG. The problems seen with growth hormone (HGH) of human origin will not be repeated with HCG as this compound is obtained in a very different way. While HCG offers no ability to improve performance or performance of women, proves to be very useful to the male steroid user. Of course, the obvious use would be to stimulate endogenous testosterone production. The activity of HCG in the human body is due to the ability of said compound to mimic LH (luteinizing hormone), a hormone produced in the pituitary that stimulates the Leydig cells in the testes to produce testosterone.

Restoring endogenous testosterone production is a major concern to the end of each cycle of steroids, as it is one at which the subnormal androgen level (due to suppression induced by the use of steroids) could be very costly in terms of lost earlier gains. The main concern is the action of cortisol, which, in many ways is balanced out by the effect of androgens. Cortisol sends the opposite message muscles than testosterone, is, or to breakdown protein in the cells. Failure to control their levels or effects on the body (due to an extremely low level of testosterone), cortisol can quickly strip much of your new muscle mass.

The main idea with HCG is to restore the normal ability of the testes to respond to endogenous luteinizing hormone. After a long period of inactivity, this ability may have been seriously reduced. In that event, the testosterone levels may not reach a normal point, although the release of endogenous LH has been resumed. Many who have suffered severe testicular shrinkage may relate, as if that were not used ancillary drugs often had to wait some time before the testicles to return to their normal size and were restored feelings of virility. The great encouragement given by the administration of HCG can cause the testicles to rapidly return to its size and activity level normal. However, we are not just looking for it to fix the problem, since high levels of testosterone resulting from its use can itself trigger a negative response inhibition in hipotálam.
