At a glance

Category: Growth Hormone
Half-life: Not characterised
Typical vial sizes: 2 mg · 5 mg
Commonly cited dose: 100–200 mcg
Frequency: once or twice daily
Routes: Subcutaneous

A 2 mg vial, worked through.

Reconstituting a 2 mg vial of Hexarelin with 2 mL of bacteriostatic water gives 1 mg/mL. A 100 mcg dose is then:

10units(0.1 mL) — about 20 doses per vial

Storage

Lyophilised (unmixed): Refrigerated; keep dry and protected from light.
Reconstituted: Refrigerate at 2-8C. Commonly cited as usable for ~30 days.

Imbimbo et al., Eur J Clin Pharmacol 1994 — PMID 7957536
Double-blind rising-dose study, 12 adult male volunteers, IV boluses of 0.5-2 mcg/kg. Reports that plasma GROWTH HORMONE peaked at about 30 min and returned to baseline within 240 min "with a half-life of about 55 min". That 55 min describes the GH response curve, NOT the elimination of hexarelin, so it cannot be used as this peptide half-life. Establishes the GH response only.
