HCG
Also known as Human Chorionic Gonadotropin, hCG
A glycoprotein hormone used clinically in fertility and endocrine contexts and discussed in peptide-adjacent markets because it acts on LH/CG receptor signaling.
Overview
HCG is human chorionic gonadotropin, a glycoprotein hormone produced during pregnancy and used medically in reproductive endocrinology. It is not a small research peptide, but it is often marketed beside peptide products because it is an injectable hormone.
The Science
HCG activates the same receptor family targeted by luteinizing hormone. In males, that can stimulate Leydig-cell testosterone production. In fertility medicine, HCG is used in ovulation induction and related reproductive protocols.
- Reproductive endocrinology - ovulation induction and fertility support under medical supervision.
- Testicular function research - LH/CG receptor stimulation and intratesticular testosterone.
- Hormone-axis literacy - interpretation requires understanding feedback between hypothalamus, pituitary, gonads, and sex steroids.
Evidence Snapshot
HCG has legitimate clinical uses, but wellness or bodybuilding claims often detach it from the monitoring and indication-specific context that make hormone therapy interpretable.
