Hexarelin6 residues (approx.)HAWFKEach bubble = one amino acid. Size = residue mass. Color = chemical class.Uses closest standard amino acids for non-standard residues.Hexarelin delivers the strongest GH pulse of any GHRP tested in humans, confirmed across dose-response trials (PMID 8126144). It also binds the CD36 cardiac receptor, a mechanism unique among secretagogues. Cortisol and prolactin elevation require strict 4-week cycling. Best suited for experienced users running short recomposition or recovery phases.
100mcg · Daily
Summary: Add 2mL BAC water to your 2mg vial. Draw to 10.0 units on a U-100 syringe for a 100mcg dose. This vial will last 20 doses.

Stack hexarelin with a GHRH, not another GHRP. The single most common mistake is pairing it with ipamorelin or GHRP-2. Both hit the same GHS-R1a receptor. You're wasting one compound. The correct partner is CJC-1295 (no DAC) or sermorelin, co-injected simultaneously. Reconstitution math for a 5mg vial: add 2 mL bacteriostatic water. That gives you 2,500 mcg/mL. On a U-100 insulin syringe, 4 units equals 100 mcg, 8 units equals 200 mcg, 12 units equals 300 mcg. For a 2mg vial with 2 mL BAC water, you get 1,000 mcg/mL; 10 units equals 100 mcg. Fasting compliance matters more with hexarelin than most peptides. Carbohydrates and fats raise somatostatin, which blunts the GH pulse considerably. No food 30 minutes before or after injection at minimum. Two hours post-meal is better. If your IGF-1 isn't moving after 4 weeks, check your fasting window before blaming the product. Refrigerate reconstituted vials and use within 3 to 4 weeks.
