HCG 5000iu
$49.00
HCG (Human Chorionic Gonadotropin) is a glycoprotein hormone with alpha and unique beta subunits. Research uses HCG to study LHCGR signaling, gonadal steroidogenesis, ovulation triggering, Leydig cell function, testicular biology, and extragonadal HCG effects. The 5000iu vial supports comprehensive reproductive endocrinology research. In-vitro use only.

HCG 5000iu — Human Chorionic Gonadotropin Research Hormone
Human Chorionic Gonadotropin (HCG) is a glycoprotein hormone composed of an alpha subunit (shared with LH, FSH, and TSH) and a unique beta subunit that confers its specific biological activity. Originally produced by syncytiotrophoblast cells of the developing placenta during pregnancy, HCG has multiple research applications in reproductive endocrinology, fertility research, and various other research fields. The 5000iu vial supports practical research design within the hormonal research peptides category.
LH Receptor Pharmacology
HCG binds the luteinizing hormone/HCG receptor (LHCGR), a G-protein-coupled receptor expressed on ovarian theca cells, granulosa cells, testicular Leydig cells, and various other tissues. Research has extensively characterized HCG-stimulated signaling cascades including cAMP elevation, steroidogenic enzyme activation, and downstream effects on steroid hormone production in animal models and isolated cell preparations.
Steroidogenesis Research
HCG’s primary research application involves stimulation of steroidogenesis in gonadal tissues. Research has documented HCG-stimulated testosterone production in Leydig cells and estrogen/progesterone production in ovarian tissue, supporting investigation of steroid biosynthesis pathways, regulatory mechanisms, and various endocrine research questions in matched cohort animal studies.
Ovulation and Reproductive Research
In reproductive research, HCG is used to trigger ovulation in animal models due to its LH-mimicking activity. The hormone supports investigation of ovulation mechanisms, oocyte maturation, corpus luteum formation, and various aspects of female reproductive biology. Research designs in fertility studies have positioned HCG as a foundational tool in reproductive endocrinology.
Testicular Function Research
HCG has been extensively studied for effects on testicular function in research animal models, with documented effects on Leydig cell function, testosterone production, spermatogenesis support, and testicular tissue maintenance. These effects have made HCG a key research tool for investigating male reproductive biology and various aspects of testicular pathophysiology in laboratory settings.
Extragonadal HCG Research
More recent research has examined HCG effects beyond classical gonadal targets. Studies have characterized HCG effects on uterine tissue, immune system parameters, vascular biology, and various other tissues expressing LHCGR receptors. This expanding research scope is broadening understanding of HCG biology beyond its classical reproductive roles in matched experimental designs.
Diagnostic and Tumor Marker Research
HCG and its subunits serve as important research reference compounds in cancer biology, where certain trophoblastic tumours and other cancers produce HCG or HCG-related molecules. Research has examined HCG production patterns, subunit relationships, and clinical correlations in various cancer research contexts as part of tumor-marker biology investigations.
Comparison With Related Research Compounds
HCG is the principal research peptide in the hormonal research category and is frequently studied alongside growth hormone axis research peptides such as Sermorelin and CJC 1295 + Ipamorelin. Parallel investigations help characterize how gonadotropin signaling compares with somatotropic axis stimulation in matched endocrine research designs.
Quality, Storage, and Compliance
Each vial of HCG 5000iu is manufactured to research-grade specifications and supplied as a sterile lyophilized powder. Store unreconstituted vials refrigerated at 2–8°C; reconstituted material should be used promptly. This HCG product is sold strictly for in-vitro laboratory research only — not for human consumption, diagnostic use, or any clinical application. Buyers must comply with all applicable provincial and federal regulations.
