The Science
What is HCG?
HCG is a glycoprotein hormone naturally produced during pregnancy. Therapeutically, it mimics LH by binding the same receptor on Leydig cells of the testes.
HCG bypasses this by directly stimulating the testes.
Laboratory Observations
Key Observed Effects of HCG
Testicular Function
Preserves natural testicular activity during TRT.
Endogenous Testosterone
Stimulates the body's own testosterone production.
Mechanism of Action
Mechanism of Action
HCG mimics LH to directly stimulate testicular function.
LH Mimicry
Binds LH receptors on Leydig cells to stimulate testosterone production.
Testicular Preservation
Maintains testicular size and function during TRT.
