GHRP-2 Dosing & Reconstitution Calculator

Growth hormone releasing peptide with strong GH release and mild appetite increase.

TL;DR — GHRP-2 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-2?
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-2?
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-2 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-2?
GHRP-2 has a short half-life of approximately 30 minutes, requiring 2–3 daily injections for sustained GH elevation. It is among the most potent GHRPs available and is often used when maximum GH pulse amplitude is desired.
How does GHRP-2 compare to GHRP-6 in terms of side effects?
GHRP-2 causes significant cortisol and prolactin elevation similar to GHRP-6, but causes less appetite stimulation. GHRP-6 has stronger ghrelin activity driving hunger; GHRP-2 is preferred when appetite side effects are a concern.
Can GHRP-2 be stacked with CJC-1295?
GHRP-2 combined with CJC-1295 (No DAC) is a potent GH-releasing combination. The GHRH analog amplifies the pituitary's response to GHRP-2, producing GH pulses significantly larger than either agent alone. Standard stacking ratio is 1:1 by microgram.
