per administration

Common schedule
Every day
Tested in people

A human trial worked out how much to take and how often, so a dosing schedule is shown.

Licensed as a medicine in Japan.

The human evidence for GHRP-2 used the intravenous route. The draw worked out here assumes a subcutaneous injection, so the amount is not a direct read-across.

Published research contexts for GHRP-2 describe 100100 mcg per administration. Descriptive only, not a recommendation.

Roughly 20–30 minutes; a short-acting secretagogue.

A growth-hormone secretagogue whose human evidence is a single 100 mcg intravenous dose given as a pituitary challenge, licensed in Japan. No subcutaneous dose-ranging schedule is established, so no schedule table is shown.

Modelled level — every day

1× is the peak after a single dose.
