Overview of HCG

HCG (Human Chorionic Gonadotropin) is a glycoprotein hormone consisting of an alpha subunit (shared with LH, FSH, and TSH) and a unique beta subunit that provides its specific activity. Naturally produced during pregnancy by placental trophoblasts, HCG has been one of the most extensively studied hormones in endocrinology and reproductive biology research for over a century.

Each vial available from SteroidsCanada.ca contains 5000IU of lyophilized HCG, manufactured to rigorous pharmaceutical-grade standards and independently verified for purity exceeding 98% via HPLC analysis. This makes it an ideal choice for qualified researchers and laboratory professionals seeking dependable, high-quality peptides for glycoprotein hormone research applications.

Mechanism of Action

HCG binds to LH/CG receptors (LHCGR) found primarily in the gonads — testicular Leydig cells and ovarian theca cells. This receptor binding mimics luteinizing hormone (LH) activity, stimulating testosterone production in males (research models) and corpus luteum function in females. Its extended half-life compared to native LH makes it a preferred research tool for studying gonadal function.

Reconstitution Guidelines

HCG is supplied as a lyophilized (freeze-dried) powder that must be reconstituted with sterile bacteriostatic water (0.9% benzyl alcohol) before use in research applications. The recommended reconstitution volume for this vial is 2mL of bacteriostatic water, which yields a concentration suitable for precise research dosing.

Reconstitution Best Practices

• Use sterile bacteriostatic water (0.9% benzyl alcohol preservative)
• Add diluent slowly along the vial wall — never directly onto the peptide cake
• Gently swirl to dissolve — never shake the vial vigorously
• Allow the peptide to fully dissolve before drawing any dose
• Store reconstituted vials at 2–8°C (refrigerator)
• Use reconstituted peptide within 28–60 days depending on specific research requirements
• Always use sterile technique when drawing from the reconstituted vial

Research Protocol Guidelines

Research protocols vary widely by study design — common ranges are 250-2500IU per research administration.

Typical Research Timeline

• Day 1-3: Initial LHCGR response research
• Week 1-2: Peak gonadal response research phase
• Week 3-4: Sustained research effects
• Week 5-8: Extended research protocol applications

Individual research results vary based on protocol design, specific research objectives, and research model characteristics. The above timeline represents commonly observed patterns in published research literature.

Research Stacking Protocols

In research applications, HCG is often studied in combination with complementary research peptides to investigate pathway interactions. Common research combinations include:

• HCG alone: Pure LH mimetic research
• HCG + Testosterone research: Endocrine axis studies
• HCG comparative: LH vs HCG research

Any research stacking protocol should be designed based on specific investigative objectives and informed by current scientific literature.
