What GHRP-2 is

GHRP-2 is a synthetic hexapeptide that functions as a potent secretagogue for endogenous growth hormone. It primarily exerts its effects by acting as an agonist at the growth hormone secretagogue receptor type 1a (GHSR-1a), commonly known as the ghrelin receptor, which is present in various tissues, including the pituitary gland and hypothalamus. By binding to this receptor, GHRP-2 stimulates the pulsatile release of growth hormone from the anterior pituitary gland and also moderates the inhibitory effects of somatostatin, further augmenting growth hormone secretion. This peptide typically exhibits a relatively short plasma half-life, often in the range of 15 to 60 minutes following administration.

In research contexts, the administration of GHRP-2 aims to investigate its potential impact on various physiological processes. While acute growth hormone release occurs rapidly, potential long-term effects on aspects like body composition, recovery, and tissue regeneration are generally observed over several weeks to months of consistent administration. Researchers frequently combine GHRP-2 with a Growth Hormone-Releasing Hormone (GHRH) analog, such as Sermorelin or CJC-1295, to create a synergistic effect that enhances both the magnitude and duration of growth hormone pulses. Research cycles commonly extend for durations ranging from 8 to 16 weeks, although this can be adjusted based on specific experimental designs. Considerations for researchers include the potential for a transient increase in appetite and possible, often mild, temporary elevations in cortisol and prolactin levels. It is important to note that GHRP-2 is intended solely for research use and is not for human therapeutic application.

Storage & handling

LYOPHILIZED (unopened): store at 2-8°C (fridge) or -20°C (freezer) long-term. Protect from light.

AFTER RECONSTITUTION: refrigerate 2-8°C. Do NOT freeze. Discard after 30 days OR if the solution becomes cloudy, discolored, or contains particulates.

What people track

Because individual responses vary so much, the useful thing is your own record: what you logged and when, how much is left in the vial, and how your chosen metrics move over the weeks. Peptide Wizard keeps all of that in one place, alongside a 3D reference vial for GHRP-2.
