Pregnyl

It naturally increases testosterone and stimulates the creation of sperm and eggs.

This hormone is produced by a part of the brain called the hypothalamus. It causes the pituitary gland to produce and release luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In men, these hormones cause the testicles to produce testosterone and sperm. Athletes use hCG to increase the body's natural production of testosterone.
