What is HCG (Human Chorionic Gonadotropin)?
HCG (Human Chorionic Gonadotropin) is a glycoprotein hormone produced by the placenta during pregnancy. It is structurally similar to luteinizing hormone (LH) and plays a crucial role in regulating reproductive processes in both men and women. HCG is primarily used in clinical settings to stimulate endogenous testosterone production in men with hypogonadism and to support fertility treatments in women, particularly in assisted reproductive technologies such as in vitro fertilization (IVF).

Can you stack HCG (Human Chorionic Gonadotropin) and NAD+ (Nicotinamide Adenine Dinucleotide)?
People sometimes combine peptides that target different pathways, but there is little controlled research on this specific pairing and the interactions aren't well characterized. Because at least one is a research-use compound, we don't publish stacking or dosing protocols here. Any combination should be discussed with a qualified clinician.

Regulatory & legal status
Approval status varies (see the chips at the top). FDA approval and compounding rules for peptides change frequently, and research-use status is not a legal clearance for human use. The FDA does not review compounded drugs for safety, effectiveness, or quality. Verify current status with primary sources before acting. Last reviewed September 21, 2026.
