SP Gonadotropin 5000 is a hormone (HCG) found in the female body during the early months of pregnancy (it is produced in the placenta). It is in fact the pregnancy indicator looked at by the over the counter pregnancy test kits, as due to its origin it is not found in the body at any other time. Blood levels of this hormone will become noticeable as early as seven days after ovulation. The level will rise evenly, reaching a peak at approximately two to three months into gestation. After this point, the hormone level will drop gradually until the point of birth. As a prescription drug, HCG offers us some interesting benefits.
Human Chorionic gonadotropin is often used with other medications as part of an in-depth Post Cycle Therapy (PCT) program focused on restoring endogenous testosterone production more rapidly at the end of a steroid cycle. Restoring endogenous testosterone production is a special concern at the conclusion of each cycle, a time when subnormal androgen levels (due to steroid-induced suppression) could be very costly to the physique. 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 to the muscles than testosterone, or to breakdown protein in the cell. Left unchecked by a low level of testosterone, cortisol can quickly strip much of your new muscle mass away. Protocols for the post-cycle use of hCG generally call for the administration of 2000-3000 Units every 2nd or 3rd day, taken for no longer than 2 or 3 weeks. If used for too long or at too high a dose, the drug may actually function to desensitize the Leydig’s cells to luteinizing hormone, further hindering a return to homeostasis. For a more comprehensive view of hCG’s role in a proper hormonal- recovery program, please refer to the Post Cycle Therapy section of this book.
Bodybuilders and athletes may also administer Human Chorionic Gonadotropin throughout a steroid cycle, in an effort to avoid testicular atrophy and the resulting reduced ability to respond to LH stimulus. In effect, this practice is used to avoid the problem of testicular atrophy, instead of trying to correct it later on when the cycle is over. It is important to remember that the dosage needs to be carefully monitored with this type of use, as high levels of hCG may cause increased testicular aromatase expression (raising estrogen levels), and also desensitize the testes to LH. As such, the drug may actually induce primary hypogonadism when misused, greatly prolonging, not improving, the recovery window. Current protocols for the use of hCG in this manner involve administering 250 IU subcutaneously every 3rd or 4th day throughout the length of the steroid cycle. Higher doses may be necessary for some individuals, but at no point should exceed 500 IU per injection.
