Growth-factor signalling
HCG
What is it?
HCG is human chorionic gonadotropin, a glycoprotein hormone. It acts at the luteinising-hormone / chorionic-gonadotropin receptor. Unlike most entries expressed in milligrams, HCG is listed in international units, which describe biological activity rather than mass.
How it is studied
The receptor pathway influences reproductive hormone production and gonadal function. Physiological effects depend on sex, endocrine status and the clinical condition. A catalogue listing does not establish that a material has the stated biological potency.
What the evidence shows
Official Pregnyl information describes a specific medicine used in defined reproductive and endocrine settings. It also states that HCG has not been demonstrated to be effective adjunctive therapy for obesity. Hormonal activity must not be repackaged as a general fat-loss claim.
Limitations & safety context
Clinical considerations include ovarian hyperstimulation and other endocrine effects in relevant populations. Source, manufacturing method and activity testing matter for glycoprotein hormones. The attachment does not establish equivalence to Pregnyl or suitability for personal use.
