What is GHRP-2?

GHRP-2 is a synthetic hexapeptide with the sequence D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2, molecular formula C45H55N9O6 and CAS number 158861-67-7. It is characterised in the literature as an agonist at the growth-hormone secretagogue receptor GHS-R1a. Kovalabs supplies it as a lyophilised reference compound for laboratory research use only.

Is GHRP-2 legal to buy in the UK?

GHRP-2 is not a controlled drug under the Misuse of Drugs Act 1971 and is not scheduled, so it may be bought and held in the UK as a laboratory reference material. It is supplied strictly for research use only and is not for human or veterinary consumption. The buyer is responsible for handling, storage and use in line with applicable law and institutional rules.

Is GHRP-2 for human use?

No. GHRP-2 is supplied strictly for laboratory research use only. It is not a licensed medicine, holds no marketing authorisation, and is not intended, labelled or sold for human or veterinary use. The milligram strength on the vial is a product specification, not a usage instruction, and no guidance on administration to any human or animal is given or implied.

What is the difference between GHRP-2 and GHRP-6?

They are two distinct synthetic hexapeptides with different sequences, both characterised in the literature as agonists at the growth-hormone secretagogue receptor. They are not interchangeable forms of one compound. Each is sold as its own reference material with its own per-batch Certificate of Analysis and HPLC specification, so the identity of what you received can be verified against the vial label.

How does GHRP-2 differ from CJC-1295 or sermorelin?

GHRP-2 is a growth-hormone secretagogue receptor agonist, while CJC-1295 and sermorelin are analogues of growth-hormone-releasing hormone and act at a different receptor. They appear in the same broad GH-axis research area but are mechanistically distinct molecules. This is a comparison of identity and receptor pharmacology only and implies nothing about combining them or about any outcome.

How does GHRP-2 differ from ghrelin?

Ghrelin is the endogenous ligand at the growth-hormone secretagogue receptor and is a 28-residue peptide carrying an octanoyl modification. GHRP-2 is a synthetic hexapeptide: far shorter, unacylated, and built with three non-standard D-amino acid residues. They are characterised as acting at the same receptor but are entirely distinct molecules, which is what makes the synthetic hexapeptide useful as a defined tool compound in receptor studies.

What purity is the GHRP-2 tested to?

Every batch is released only after independent analytical testing, with purity assessed by HPLC at 99% or higher and identity confirmed against the expected mass for C45H55N9O6. A batch-specific Certificate of Analysis accompanies the material and current documents are published on our CoAs page, so the specification can be checked against the vial before any work begins.

Is all GHRP-2 the same?

No. Material sold under the same name can differ substantially in identity and purity, which is why documentation matters more than the label. Only a batch that ships with a certificate of analysis from an independent laboratory can be treated as a characterised reference compound; without one, the contents of the vial are an assertion rather than a verified specification.

How do I identify which batch I have received?

Match the compound name and the batch number printed on the vial label to the corresponding per-batch Certificate of Analysis on the CoAs page. The certificate states the identity result and the HPLC purity figure for that specific batch, so you can verify exactly what was supplied rather than relying on the product listing alone.

What does the research on GHRP-2 investigate?

The published literature uses GHRP-2 as a tool compound to probe binding and signalling at the growth-hormone secretagogue receptor GHS-R1a and the wider ghrelin pathway, in in-vitro systems and pre-clinical models, including structure-activity comparisons across the peptidic secretagogue series. None of that work establishes a benefit, effect, safety profile or outcome in humans.

How should GHRP-2 be stored?

Store the lyophilised solid at -20C, kept dry and protected from light. Once reconstituted at the bench with a research solvent such as bacteriostatic water, hold the material at 2-8C. Storage guidance describes handling of a laboratory reference material and is not instruction for any use in a human or animal.

What is GHRP-2 supplied as?

It is supplied as a white to off-white lyophilised solid in a sealed vial, sold per vial and despatched from the UK. It is intended to be reconstituted at the bench with a research solvent such as bacteriostatic water, which Kovalabs stocks as a separate research consumable. The stated milligram figure is a product specification only.

Can I buy GHRP-2 in the UK from Kovalabs?

Yes. Kovalabs supplies GHRP-2 in the UK as a research chemical for laboratory use only, despatched from the UK with a batch-specific certificate of analysis. It is not sold for human or veterinary consumption and is not a licensed medicine; the buyer is responsible for compliant handling under their own obligations.
