GHRP-2 is a synthetic growth-hormone-releasing hexapeptide studied in research into ghrelin and GHS-receptor signalling within GH-axis models.
GHRP-2 is a synthetic hexapeptide and an agonist of the growth-hormone secretagogue receptor (GHS-R1a), the ghrelin receptor. Its sequence is D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2, with molecular formula C45H55N9O6, molecular weight 818.0 g/mol and CAS number 158861-67-7. Kovalabs supplies it as a research reference compound, lyophilised, for laboratory use only.
The amide-capped C-terminus and the three non-standard residues (D-alanine, D-2-naphthylalanine and D-phenylalanine) are characteristic of its identity and distinguish it from the natural ghrelin sequence, which is a 28-residue acylated peptide. GHRP-2 sits in the GH-axis research category as a reference material, not as a medicine or supplement.
GHRP-2 is not a controlled drug under the Misuse of Drugs Act 1971 and is not scheduled. It is supplied in the UK strictly as a research chemical for laboratory use only. It is not a licensed medicine, holds no marketing authorisation, and cannot be sold or supplied for human or veterinary consumption. The buyer is responsible for lawful, compliant handling under their own jurisdiction. See our research disclaimer.
Each batch is released after independent testing. Purity is assessed by HPLC at 99% or greater, and identity is confirmed by HPLC retention-time matching (HPLC-RTM) against a reference standard for C45H55N9O6 (CAS 158861-67-7, PubChem CID 6918245). A batch-specific Certificate of Analysis accompanies the material; current documents are published on our CoA page. This verification is what separates a characterised reference compound from unverified material, which is why "is all GHRP-2 the same" has a clear answer: only a CoA-backed batch is.
The published literature investigates GHRP-2 as a tool compound for probing GHS-R1a binding and signalling and the wider ghrelin / growth-hormone secretagogue pathway in in-vitro and pre-clinical model systems, including structure-activity work across the peptidic secretagogue series. People searching for GHRP-2 benefits or effects should note that none of this establishes any benefit, effect or outcome in humans; it is not a licensed medicine and no human or veterinary application is intended or implied.
These are distinct molecules studied at the same receptor. GHRP-2 and GHRP-6 are both synthetic hexapeptides characterised as GHS-R agonists, differing in sequence; ipamorelin is a pentapeptide described in the literature as a more selective GHS-R agonist. All three are separate from the growth-hormone-releasing-hormone analogues CJC-1295 (no DAC) and sermorelin, which act at a different receptor. This is an identity and pharmacology comparison only, not a protocol or any guidance for use in a body.
GHRP-2 is supplied as a white to off-white lyophilised solid for reconstitution at the bench with a research solvent such as bacteriostatic water. Store lyophilised material at -20C, dry and protected from light; hold reconstituted material at 2-8C. Sold per vial as a product specification, despatched from the UK. For laboratory research use only; not for human or veterinary use.

This is my second time ordering, and everything has been fantastic once again. Smooth delivery, packed very well, excellent product quality, and no issues whatsoever. Really happy with the service and will definitely be my go to moving forward.
Highly recommend.
For context, I’ve used many peptide companies over the years. And I can confidently say kovalabs sit in their own lane. The efforts they go through to get ISO testing is remarkable, more importantly the results themselves are also consistently superb. Shipping has always arrived next day, packaging is professional and packed securely. With nice personal touches too. Support team are fantastic also. The only company I’d recommend for peptides moving forward.
Highly recommend, pleasure to deal with and very attractive offers too. Very happy customer
Best customer service, pricing and quality for peptides! I'm a loyal customer!
The kovalabs team deserves some sort of award. By far the best customer support I’ve received perhaps in my life, with genuinely kind and caring people. The vials themselves look very premium and professional, but more importantly I can vouch that the quality of the stuff is truly top tier. I continue to recommend to all
Great Customer Service Fast Response will definitely be ordering again
Faultless!
Cannot fault these guys, from ordering to delivery to product quality. 3rd order and always outstanding service. Products are proving great for my research too, best provider around. Wont go anywhere else now.
Will happily do business with them all day long again and again. Brilliant service and products.
