Buy GHRP-2 — 10 mg Lyophilized Vial
Somatotropic signalling work — centred on cross-compound potency mapping.
GHRP-2 is a hexapeptide ghrelin-receptor agonist, one of the earliest GHRPs developed. It is a benchmark compound in growth-hormone-secretagogue research — studied alongside newer analogs like ipamorelin and hexarelin.

Key facts
- Early-generation hexapeptide GHRP
- Strong GH-release profile in research
- Appetite-stimulating effects via ghrelin receptor
- Benchmark comparison compound for newer secretagogues
Mechanism in the literature
GHRP-2 binds the GHS-R1a (ghrelin) receptor in the anterior pituitary and hypothalamus, driving GH release and appetite signaling. Its HPA-axis engagement (cortisol/prolactin) is greater than newer selective analogs.
Often paired with
Buyers viewing GHRP-2 typically also consider CJC-1295 with DAC, Sermorelin and Gonadorelin Acetate. Each is in stock, sealed under nitrogen with a lot-matched CoA.
Research use-cases
- Early-generation hexapeptide GHRP
- Strong GH-release profile in research
- Appetite-stimulating effects via ghrelin receptor
- Benchmark comparison compound for newer secretagogues
Handling in the lab
Reconstitute under sterile technique with bacteriostatic water. Typical volumes range from 1–3 mL depending on the target working concentration. Swirl gently — do not shake — to avoid peptide shearing.
Stacking and paired-compound work
Often combined with GHRH analogs (CJC-1295, Tesamorelin) in dual-pathway GH research.
Storage and shelf-life
Lyophilized powder is stable at ambient shipping temperatures. Once reconstituted with bacteriostatic water, store at 2–8 °C and use within 28 days. For long-term storage of unreconstituted vials, freeze at −20 °C and protect from light.
Frequently asked
How does GHRP-2 differ from ipamorelin?
GHRP-2 has stronger HPA-axis effects (cortisol, prolactin). Ipamorelin is more selective for GH release. Both act on the same ghrelin receptor.
How does it differ from GHRP-6?
GHRP-6 produces substantially more appetite stimulation and prolactin elevation. GHRP-2 is "cleaner" but less selective than ipamorelin.
What is its half-life?
Short — under 30 minutes in research models.
Is it combined with GHRH analogs?
Yes — dual-pathway GH research stacks GHRH + GHRP for amplified release.
