Published research contexts for Gonadorelin describe 5–100 mcg per administration. Descriptive only, not a recommendation.
Only a few minutes in plasma, so any curve here is a brief spike.
A gonadotropin-releasing hormone (the natural decapeptide), licensed as a medicine and given either as a single dose for a pituitary challenge or in small pulses from a pump every 60–120 minutes. Neither pattern is a standing subcutaneous escalation, so no schedule table is shown.
Modelled level — every day
1× is the peak after a single dose.
- Steady-state peak
- 0.97× single dose
- Time to steady state
- 1hours
- Administrations
- 7/ week

About five half-lives
Where these numbers come from
- Gonadorelin (Factrel / Lutrepulse) product literatureThe licensed decapeptide is used as a single pituitary-challenge dose or as pulsatile microdoses; no daily subcutaneous schedule is established.
