HCG

Price range: $50.00 through $266.00 / 10 Vials

HCG (Human Chorionic Gonadotropin) is a highly purified glycoprotein hormone derived from recombinant DNA technology or natural sources. It functions as a powerful analog of Luteinizing Hormone (LH). In research settings, HCG is primarily utilized to study the stimulation of interstitial cells (Leydig cells) to produce testosterone and to investigate the preservation of reproductive functions during various hormonal experimental protocols.

Mechanism of Action

LH Mimicry: HCG shares a nearly identical $\alpha$-subunit with LH and binds to the same LH/hCG receptors. This binding triggers the biological responses normally associated with natural LH.Stimulation of Leydig Cells: In male research models, HCG acts directly on the Leydig cells in the testes to stimulate the synthesis and secretion of endogenous testosterone.Follicular Maturation: In female research models, it supports the final maturation of ovarian follicles and can trigger ovulation, mimicking the mid-cycle LH surge.Maintenance of Intratesticular Testosterone: It is frequently studied for its ability to prevent testicular atrophy and maintain fertility markers during periods of exogenous hormone suppression.
