In the field of bodybuilding, Pregnyl HCG has been reported to be used both in phases during prolonged use of anabolic steroids and after discontinuation of anabolic steroids.
These two schemes of use are related to the fact that prolonged use of anabolic steroids not only suppresses the body’s secretion of LH hormone and thus also the natural testosterone production, but also leads to a shrinkage of the testicles called atrophy, which involves desensitization of Leyding Cells compared to the testosterone release stimulating effect of LH hormone is accompanied. Studies show that even after more than 20 weeks of testosterone use, the body releases normal amounts of LH hormone within a short time, but the testes take up to 10 weeks to react properly to this hormone.
A phased use of Pregnyl HCG during steroid therapy is intended to counteract this atrophy and desensitization of the testes from the outset, and, according to anecdotal reports from users, often results in an additional boost in force and mass buildup.
The application of Pregnyl for men during the weaning phase is intended to flood the testes with large amounts of “artificial LH hormone”, which causes the testes to be sensitized to stimulation of testosterone production by the body’s own LH hormone and thus react faster to the body’s own LH hormone ,
In the mid-fifties of the 20th century, the doctor propagated Simmons also recommended the use of hCG during a diet with greatly reduced calorie intake (500 to 1000 calories per day). According to its publication, Pregnyl HCG should suppress hunger in such a scenario on the one hand, and promote the elimination of stubborn fat deposits on the other hand. Although there are still clinics that offer this type of dietary support, this area of application of MSD Pregnyl among scientists is refuted, which goes so far that even with American hCG preparations in the leaflet even explicitly must be noted that this drug is not to support the weight reduction is suitable.
