What is HCG?
HCG mimics luteinizing hormone (LH), supporting endogenous testosterone production and testicular function during research protocols.
Mechanism of Action
Binds the LH receptor on Leydig cells, stimulating testosterone and intratesticular steroidogenesis. Also used in fertility research.
Key Benefits
- Maintains testicular volume
- Supports endogenous testosterone
- Used in PCT research
