Fertigyn (Pregnyl)

The main reason for the athletes' interest in human chorionic gonadotropin is that exogenous hCG has almost the same qualities as the pituitary luteinizing hormone. In males, luteinizing hormone stimulates the germ cells in the testicles and increases the production of androgenic hormones (testosterone). Therefore, inject Pregnil is used by athletes for enhanced testosterone production. Human chorionic gonadotropin is most often used in combination with anabolic steroids (at the end or in the middle of a steroid cycle). As already mentioned, feedback-based anabolic steroids inhibit the production of follicle-stimulating and luteinizing hormones, as a result of which testosterone production is reduced. Since the body normally needs time to normalize the process of testosterone production, a very difficult transitional phase occurs for an athlete after they stop taking a steroid, which often passes with a significant loss of strength and mass. As the steroid course ends, the use of human chorionic gonadotropin helps to return the testes to their original state, including their size. Temporary injections of human chorionic gonadotropin while taking anabolic steroids can prevent testicular atrophy, so many athletes take Pregnil in the middle of a steroid cycle for 2–3 weeks. It is noticed that just at this time the athlete achieves his best success in terms of mass and strength. This is explained by the fact that, on the one hand, the athlete has a high level of testosterone due to the use of hCG, and on the other hand, there is a high concentration of anabolic active substances in the blood due to the use of steroids.
