Suggested Protocol
Classical stimulation-test protocols administer 1mcg/kg as a single subcutaneous or intravenous bolus, measuring GH response at 15, 30, 60, and 90 minutes. Research replicating these protocols consumes roughly 70–100mcg per 70–100kg subject per challenge.
The 2mg vial is the Geref-heritage sizing. It maps directly to the stimulation-test use case that drove sermorelin's original approval: a single 1-microgram-per-kilogram intravenous or subcutaneous challenge to probe somatotrope responsiveness as a diagnostic readout for growth hormone deficiency.
