HCG

The LH Mimetic & Gonadal Restoration Peptide

HCG is a complex glycoprotein hormone that functions as a structural and functional analog to Luteinizing Hormone (LH). It is a critical tool in endocrine research for its ability to maintain gonadal function during periods of hormonal suppression.

Mechanism: Binds directly to the LH/hCG receptor (LHCGR) on Leydig cells, stimulating the endogenous production of testosterone and maintaining intratesticular signaling.
Key Advantage: Unlike exogenous testosterone, which shuts down the natural hormonal axis, HCG mimics the body’s “signal” to keep the testes active, preventing atrophy and preserving germ cell maturation.
Research Focus: HPTA restoration (Post-Cycle Therapy models), fertility preservation, and the mitigation of secondary hypogonadism.
Purity: >99% (Third-party HPLC/MS verified).
Format: Lyophilized powder for laboratory research use

HCG (Human Chorionic Gonadotropin) Research-Grade Gonadotropin & LH Mimetic

Product Overview

Human Chorionic Gonadotropin (HCG) is a complex glycoprotein hormone composed of 237 amino acids. While naturally produced by the trophoblast cells during pregnancy, HCG is of significant interest in endocrine research due to its structural and functional similarity to Luteinizing Hormone (LH).

In scientific literature, HCG is classified as an LH mimetic because it shares a common alpha subunit with LH, FSH, and TSH, and possesses a beta subunit that allows it to bind specifically to the LH/hCG receptor (LHCGR). In male biological models, HCG acts directly on the Leydig cells within the testes to stimulate the synthesis and secretion of endogenous testosterone. Unlike exogenous testosterone, which suppresses the Hypothalamic-Pituitary-Testicular Axis (HPTA) and leads to gonadal atrophy, HCG is utilized in research to maintain or restore intratesticular testosterone levels and preserve germ cell maturation (spermatogenesis). This makes it an essential compound for studying endocrine recovery, fertility preservation, and the mitigation of steroid-induced hypogonadism.

Primary Research Applications

Under doctor-reviewed scientific literature, HCG is frequently utilized in in vitro and animal model studies to observe:

HPTA Axis Modulation: Investigating the restoration of the natural hormonal feedback loop following suppression by exogenous androgens.
Leydig Cell Function: Observing the direct stimulation of testosterone production and the prevention of testicular atrophy in castrate-resistant models.
Spermatogenesis Support: Measuring the maintenance of the microenvironment necessary for sperm production and maturation.
Steroidogenesis Research: Tracking the conversion of cholesterol into pregnenolone, the “mother hormone,” which serves as a precursor to all other steroid hormones.
