GHRP-6 Dosing & Reconstitution Calculator

Growth hormone releasing hexapeptide that strongly stimulates appetite and GH.

TL;DR — GHRP-6 is a growth hormone peptide with a typical starting dose of 100 µg. For a 5 mg vial, add 2 mL bacteriostatic water to yield 2500 µg/mL.

Frequently Asked
How do I reconstitute GHRP-6?
Add 2 mL of bacteriostatic water to a 5 mg vial, injecting slowly down the inside wall. Swirl gently; never shake. This yields a concentration of 2500 µg/mL.
What is the recommended dose of GHRP-6?
A typical research dose is 100 µg. Consult the ASCEND calculator for your specific vial concentration and draw volume.
How many doses are in a GHRP-6 vial?
A 5 mg vial reconstituted with 2 mL BAC water yields approximately 50 doses at 100 µg each.
Peptide Intelligence
What is the half-life of GHRP-6?
GHRP-6 has a short half-life of approximately 15–60 minutes, requiring 2–3 daily subcutaneous injections. Its strong appetite stimulation via ghrelin mimicry distinguishes it from more selective GHRPs like Ipamorelin.
Why does GHRP-6 cause such strong appetite stimulation?
GHRP-6 has high affinity for the ghrelin receptor (GHS-R1a) and significantly elevates circulating ghrelin. Ghrelin is the primary hunger-stimulating hormone, acting on the hypothalamus. This appetite stimulation is sometimes used intentionally in mass-building research protocols.
What is the GI protective effect of GHRP-6?
GHRP-6 has been studied for gastroprotective effects partly through its ghrelin activity. Ghrelin receptors are expressed throughout the GI tract, and GHRP-6 may protect against mucosal damage and improve gastric motility in research models.
