GHRP-2
GHRP-2 is a synthetic hexapeptide growth-hormone secretagogue. It is among the stronger secretagogues studied in the GH category.
Also known as: Growth hormone releasing peptide-2
Research context
- Synthetic hexapeptide that stimulates growth-hormone release.
- Common in laboratory GH-axis research.
- Available in 5mg and 10mg.

What GHRP-2 is
GHRP-2 (growth hormone-releasing peptide-2) is a synthetic ghrelin-receptor agonist. It stimulates growth hormone release by acting on the ghrelin receptor, and unlike some of the older secretagogues it was designed to be selective for that receptor — it does not appreciably stimulate prolactin or ACTH, which is a feature that distinguishes it in research protocols where those side pathways are unwanted noise.
Where it sits in the secretagogue category
| Compound | Receptor / class | Selectivity character | Clinical documentation |
|---|---|---|---|
| GHRP-2 | Ghrelin-receptor agonist | Selective for ghrelin receptor; low prolactin/ACTH effect | Preclinical + early-phase |
| GHRP-6 | Ghrelin-receptor agonist | Broader secretagogue activity (GH + insulin + cortisol signalling) | Preclinical + early-phase |
| Ipamorelin | Ghrelin-receptor agonist | Selective; the most handled compound on this side of the shelf | Clinical studies; not approved as a product |
| CJC-1295 (no DAC) | GHRH analogue | Acts on a different receptor (GHRH receptor) — complementary, not interchangeable | Preclinical + early-phase |
The practical takeaway: if the research question is specifically “ghrelin-receptor stimulation without the broader secretagogue effects”, GHRP-2 is the selective tool here. For the most commonly handled selective ghrelin-receptor compound, that is ipamorelin; for the broader-activity profile, GHRP-6.
How it is supplied and handled
GHRP-2 ships as a lyophilised (freeze-dried) powder in a sealed vial — the standard stable form for research peptides. It is available here in 5mg and 10mg vials. Once reconstituted with bacteriostatic water it should be kept refrigerated and handled cold-chain; the reconstitution guide covers the volumes, arithmetic and storage handling for this class of compound. Every batch is supplied with a certificate of analysis (see the lab and COA policy); batch-specific COAs can be requested via the contact page before ordering.

Common questions
What is the difference between GHRP-2 and GHRP-6?
Both are ghrelin-receptor agonists, but GHRP-2 is more selective for that single receptor, while GHRP-6 has broader secretagogue activity affecting other hormonal signalling pathways in addition to GH release. That selectivity difference is the main research reason to choose one over the other.
How is GHRP-2 different from ipamorelin?
Both are selective ghrelin-receptor agonists. Ipamorelin has a larger body of published clinical studies and is the more commonly handled compound on this side of the shelf; GHRP-2’s evidence base is preclinical and early-phase.
Does GHRP-2 raise prolactin?
One of the reasons GHRP-2 is studied is that it shows minimal prolactin (and ACTH) elevation compared with older, broader secretagogues. The published data support that character, but as always with research chemicals, the literature is the source to check.
What strengths do you stock and how do I pay?
5mg at £5.61 (bank £5.05) and 10mg at £9.35 (bank £8.41). No minimum order; card checkout runs on Stripe, bank orders confirm on clearance.
Can GHRP-2 be combined with a GHRH analogue?
In research protocols, yes — because it acts on the ghrelin receptor, it is complementary to GHRH-receptor compounds like CJC-1295 and tesamorelin rather than redundant. See those pages for the other side of the pairing.
Is GHRP-2 a medicine?
As sold here it is a research chemical. It is not a licensed medicine in the UK, it is not for human or veterinary use, and nothing on this page is medical advice or a dosing recommendation.
