Quantity: 5000 IU per vial
SKU: G5K

Product Overview

Human Chorionic Gonadotropin (HCG) is a glycoprotein heterodimeric hormone composed of an alpha subunit (shared with LH, FSH, and TSH) and a unique beta subunit that confers biological specificity. It binds with high affinity to the LH/CG receptor (LHCGR), activating the same downstream cAMP/PKA signaling pathway as luteinizing hormone (LH).

In males, HCG stimulates Leydig cells to produce testosterone and supports spermatogenesis, making it a key tool in studies of testicular steroidogenesis and the hypothalamic-pituitary-gonadal (HPG) axis. In females, it triggers ovulation and supports corpus luteum function. Research applications include fertility biology, steroidogenesis studies, and HPG axis pharmacology.

Research Applications

HCG has been examined in experimental studies related to:

• LH/CG receptor (LHCGR) pharmacology and cAMP/PKA signaling
• Testicular steroidogenesis and testosterone production research
• Leydig cell function and gonadotropin receptor studies
• Ovarian stimulation, follicular development, and ovulation research
• HPG axis dynamics and gonadotropin feedback research
• Fertility protocol and hypogonadism preclinical models

Handling and Storage (Laboratory Guidance)

This product is supplied as a lyophilized peptide powder.

Typical laboratory handling recommendations include:

• Store at 2–8 °C upon receipt.
• Protect from heat, moisture, and direct light.
• Avoid excessive agitation of the solution to maintain peptide stability.
• Reconstitution, if required for laboratory experiments, should be performed using appropriate sterile laboratory techniques.
• Use of acetic acid water (0.6%) or sterile bacteriostatic water is recommended for peptides with low aqueous solubility.
