Positive aspects of HCG

Stimulation of natural testosterone

HCG is not direct testosterone — it causes the body to produce the hormone on its own.

Fertility preservation

Unlike TRT, HCG is often used when a man also wants to preserve fertility.

Support of testicular function

May help reduce testicular shrinkage during anabolic steroid use or TRT.

Long history of use

HCG has been used in medicine for decades and is reasonably well studied.
