HCG 10000IU Research Peptide: A Glycoprotein Hormone for Reproductive & Endocrine Studies

If your research investigates reproductive endocrinology, gonadal function, or the molecular mechanisms of fertility regulation, HCG 10000IU research peptide — also known as Human Chorionic Gonadotropin — offers a precisely defined and extensively validated synthetic tool. HCG is a polypeptide hormone composed of an alpha and a beta sub-unit. The alpha sub-unit is essentially identical to the alpha sub-units of the human pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), as well as to the alpha sub-unit of human thyroid-stimulating hormone (TSH).

The beta sub-units of these hormones differ in amino acid sequence. Obtained from human pregnancy urine and standardised by biological assay, HCG is supplied as a sterile lyophilised powder available in multi-dose vials containing 10,000 USP units. This makes HCG 10000IU research peptide an invaluable tool for laboratories investigating reproductive biology, endocrinology, fertility, and gonadal steroidogenesis.

At Chinese Grey Peptides, we supply high‑purity HCG 10000IU research peptide to research institutions and wholesale buyers across the United Kingdom, France, Germany, Spain, Sweden, Italy, and the USA. Every batch is lyophilised, tested for biological activity, and accompanied by a Certificate of Analysis (COA), ensuring your investigations into reproductive endocrinology and gonadal function begin with uncompromising quality.

What Is HCG and How Does It Work?

To fully appreciate the research potential of HCG 10000IU research peptide, it is essential to understand its biochemical structure, its mechanism of action as an LH analogue, and its distinct pharmacological properties.

The Glycoprotein Hormone

HCG is a glycoprotein hormone with a molecular weight of 38,000 Da, produced and secreted by the placental villi. Structurally, it exists as a non‑covalently linked heterodimer of α and β subunits. The α‑chain shares an identical protein structure with the α‑chains of luteinizing hormone (LH) and thyroid‑stimulating hormone (TSH), whereas the β‑subunit is unique. Although HCG is biologically and immunologically similar to LH, it possesses distinct structural components.

The compound is supplied as a sterile lyophilised powder in vials containing 10,000 USP units. When reconstituted with 10 mL of accompanying diluent, each vial contains 10,000 USP units of chorionic gonadotropin.

Mechanism of Action: LH Receptor Agonism

The biological activity of HCG 10000IU research peptide is mediated through its action as an LH receptor agonist:

• LH Receptor Binding: The action of HCG is virtually identical to that of pituitary LH, although HCG appears to have a small degree of FSH activity as well. It binds to LH receptors on gonadal cells, mimicking the physiological action of LH.

• Stimulation of Gonadal Steroidogenesis: HCG stimulates production of gonadal steroid hormones by stimulating the interstitial cells (Leydig cells) of the testis to produce androgens and the corpus luteum of the ovary to produce progesterone.

• Androgen Stimulation in Males: Androgen stimulation in the male leads to the development of secondary sex characteristics and may stimulate testicular descent when no anatomical impediment to descent is present.

• Ovulation Induction in Females: During the normal menstrual cycle, LH participates with FSH in the development and maturation of the normal ovarian follicle, and the mid‑cycle LH surge triggers ovulation. HCG can substitute for LH in this function.

• Corpus Luteum Maintenance: During a normal pregnancy, HCG secreted by the placenta maintains the corpus luteum after LH secretion decreases, supporting continued secretion of oestrogen and progesterone and preventing menstruation.

Pharmacokinetic and Bioactivity Profile

The biological activity of HCG preparations is standardised by biological assay. Highly purified HCG preparations demonstrate bioactivity of ≥10,000 IU/mg powder. Recombinant HCG preparations have demonstrated higher purity and fewer local injection site adverse effects compared to urinary-derived HCG.

Accurate characterisation of HCG 10000IU research peptide is essential for reproducible experimental design.

Reconstitution & Handling Protocol for HCG 10000IU

Proper reconstitution of HCG 10000IU research peptide is critical for maintaining its structural integrity and biological activity.

Step 1 – Preparation

• Bring the sealed HCG vial and the accompanying sterile diluent (Bacteriostatic Water for Injection) to room temperature.

• Clean your work surface with 70% ethanol and lay out sterile syringes, alcohol wipes and a clean work mat.

Step 2 – Vial Sanitisation

• Wipe the rubber stoppers of both the HCG vial and the diluent vial with a fresh 70% ethanol wipe. Allow the alcohol to evaporate completely before piercing.

Step 3 – Reconstitution

• Transfer the contents of one vial of sterile diluent into one vial of freeze‑dried powder.

• The resulting 10 mL of solution contains 10,000 IU chorionic gonadotropin.

• Agitate gently until the solution is clear and fully dissolved. Do not shake vigorously, as shaking can cause denaturation.

Step 4 – Storage and In‑Use Management

• Once reconstituted, the solution must be refrigerated (2‑8°C).

• Reconstituted HCG is stable when refrigerated for up to 60 days.

• Record the date of reconstitution on the vial label.
