Human chorionic gonadotropin — the classic reference hormone of reproductive-axis research. 5000iu vial.
HCG (human chorionic gonadotropin) is a glycoprotein hormone that structurally mimics luteinizing hormone (LH). It is a foundational molecule in reproductive endocrinology research.
What HCG is
- A glycoprotein hormone of two subunits (alpha + beta)
- Its alpha subunit is identical to LH, FSH and TSH — the beta subunit gives it LH-like action
- One of the longest-studied hormones in endocrine science
Research suggests HCG may help with
- LH-receptor signaling — gonadal stimulation models
- Testosterone production — Leydig-cell studies
- Reproductive-axis research — HPG feedback studies
- Ovulation biology — follicle-maturation research
Research areas at a glance
| Research area | What studies explore |
|---|---|
| LH receptor | Receptor binding and cAMP signaling in gonadal cells |
| Steroidogenesis | Testosterone synthesis pathways in Leydig-cell models |
| HPG axis | Feedback loops between brain, pituitary and gonads |
How HCG is studied to work
1. LH-receptor mimicry
- Binds and activates the LH receptor with a much longer half-life than LH itself
- This durability is why researchers use it as an LH surrogate
2. Steroidogenic signaling
- Studied for triggering the cAMP → StAR → steroid synthesis cascade in gonadal cells

Product specifications
| Specification | Detail |
|---|---|
| Vial size | 5000iu HCG |
| Form | Lyophilized (freeze-dried) powder |
| Storage | Cool, dry place away from light; refrigerate after reconstitution |
| Intended use | Laboratory research only — not for human consumption |
Summary
In research settings, HCG is studied for:
- LH-receptor agonist glycoprotein
- Steroidogenesis and HPG-axis research
- A century-old cornerstone of endocrinology
HCG is NOT a hormone therapy — it is a research standard of the reproductive axis.
Some molecules are trends; HCG is a textbook chapter.

Reconstitution / BAC Water
Reconstitution / BAC Water
All vial peptides are supplied in lyophilized powder form for research purposes. Reconstitution / BAC Water requires bacteriostatic (BAC) water, and the amount used depends on the concentration required for your research protocol.
Storage & Handling
Storage & Handling
Before reconstitution, keep sealed vials cool, dry, and away from direct light. For longer-term storage, freezing is recommended to preserve stability.
After reconstitution, store refrigerated and use within 30 days for best stability.
