per administration
A human trial worked out how much to take and how often, so a dosing schedule is shown.
Licensed as a medicine in the US and EU.

Published research contexts for HCG describe 250–500 mcg per administration. Descriptive only, not a recommendation.
Biphasic, roughly a day to a day and a half; longer than the short peptides here.
Human chorionic gonadotropin is a glycoprotein hormone, not a short peptide, licensed as a medicine and given subcutaneously or intramuscularly. Amounts are usually stated in international units (the recombinant 250 mcg form is about 6,500 IU); no subcutaneous dose-ranging escalation applies, so no schedule table is shown.
Modelled level — 2x per week
1× is the peak after a single dose.
- Steady-state peak
- 1.19× single dose
- Time to steady state
- 6.3days
- Administrations
- 2/ week

About five half-lives
Where these numbers come from
- Choriogonadotropin alfa (Ovidrel) and urinary hCG product literatureA licensed glycoprotein hormone; the recombinant form is a 250 mcg subcutaneous dose, urinary forms are dosed in international units.
