HCG

Registered fertility / endocrine medicine.

What it does / how it works

A pregnancy glycoprotein that acts on LH receptors. In males it can keep testicular signalling running. Dosed in IU. Raises oestrogen and haematocrit if pushed.

Class	Glycoprotein LH-receptor agonist
Typical vial	5,000 or 10,000 IU
Reconstitution	BAC water. Dose in IU, not mg.
Storage after mix	2–8°C, use within 28 days

Protocol

Goal	Dose	How often	How long	Route
Weeks 1-16 male endocrine range	500-1500 IU	2-3x weekly	8-16 weeks	IM or SubQ
Trigger (specialist)	5000-10000 IU	Once	Single dose	IM or SubQ

HCG FAQ — Australia

Where can I buy HCG in Australia?

ELV8 Labs offers HCG in 5,000 IU vials, third-party tested at a leading Australian university. For research purposes only.

Why is HCG dosed in IU rather than mg?

HCG is a glycoprotein with variable glycosylation patterns, making weight-based dosing unreliable. International Units (IU) measure biological activity rather than mass, providing consistent dosing across different preparations. This is standard for glycoprotein hormones in both clinical and research settings.

How is HCG different from LH?

HCG and LH share the same alpha subunit and bind the same receptor (LH/CG receptor), but HCG has a longer half-life due to additional glycosylation on its unique beta subunit. This extended half-life makes HCG more practical for research dosing than recombinant LH.
