Human chorionic gonadotropin
HCG 10.000 IU
A glycoprotein made of two different chains. The alpha subunit is shared with several pituitary hormones; the beta subunit is what gives it its identity and what specific tests recognise. It is measured in International Units because what is standardised is its biological activity, not its mass: two batches with the same milligrams may not have the same potency.
- CAS
- 9002-61-3
- Molecular weight
- ≈ 36.700 Da (varía con el grado de glicosilación)
- Purity
- ≥ 98% verified by HPLC
- Presentation
- Amber glass vial with lyophilized powder, vacuum sealed.
- Includes 3 ml BAC waterIn the same box, at no cost.
How it works
- Agonism of the LH/CG receptor, which it shares with luteinising hormone.
- In testicular tissue, stimulates steroidogenesis in Leydig cells.
- Longer half-life than endogenous LH because of its sialic acid content.
Qué dice la evidencia
- LH/CG receptor agonist: reproduces the luteinising hormone signal on Leydig cells.
- Standardised by biological activity in International Units, not by mass.
Route described in the studies

Preguntas frecuentes
Why does the calculator not include it?
Because this vial is measured in International Units and the calculator converts mass. An IU measures biological activity, and its equivalence in milligrams depends on each batch's standard: applying a fixed factor would give the wrong dose. The conversion comes from the batch certificate of analysis.
What does 10,000 IU on the vial mean?
It is the vial's total activity content, not the dose. Reconstituted in 5 ml, that leaves 2,000 IU per ml.
