What is GHRP-6?
GHRP-6 (growth-hormone-releasing peptide 6) is a synthetic hexapeptide with the sequence His-D-Trp-Ala-Trp-D-Phe-Lys-NH2 and the molecular formula C46H56N12O6 (molecular weight 873.0 g/mol). It is identified by CAS number 87616-84-0 and PubChem CID 9919153, and is also known as SKF-110679. It is supplied as a lyophilised powder for laboratory research use only.
It belongs to the growth-hormone secretagogue (GHS) family of peptides. As a reference compound it is studied alongside other GH-axis research peptides such as Ipamorelin and Sermorelin.
Is GHRP-6 legal in the UK?
GHRP-6 is not a controlled drug under the Misuse of Drugs Act 1971, and it is not a licensed medicine in the UK. Kovalabs supplies it strictly as a research chemical for in-vitro and laboratory use. It is not for human or veterinary consumption and is not sold for any personal use. The purchaser is responsible for compliant handling, storage and disposal. Please review our research disclaimer before ordering.
How is identity and quality assured?
Every batch is released only after independent third-party analysis. Purity is assessed by HPLC at >= 99%, and identity is confirmed against the expected mass and the published identifiers (CAS 87616-84-0, PubChem CID 9919153, InChIKey WZHKXNSOCOQYQX-FUAFALNISA-N). A batch-specific Certificate of Analysis is available so the material can be verified before use. Browse all current Certificates of Analysis.
What does the research on GHRP-6 investigate?
The published literature investigates GHRP-6 as a ligand of the growth-hormone secretagogue receptor (GHS-R), part of the ghrelin signalling pathway, in pre-clinical and in-vitro model systems. Reported observations describe receptor-level activity within this pathway in laboratory contexts only. None of it establishes a benefit, effect or outcome in humans, and GHRP-6 is not a licensed medicine. It is not supplied for and must not be used for any human application of any kind. For the mechanistic and pre-clinical detail, see our GHRP-6 research monograph.
Synthesis and supply
GHRP-6 is produced by solid-phase peptide synthesis and supplied as a lyophilised (freeze-dried) white to off-white powder. For laboratory work it is typically reconstituted with a suitable solvent such as bacteriostatic water. Store the lyophilised powder at -20C, dry and protected from light; hold reconstituted material at 2-8C. For research comparisons within the GH axis, see IGF-1 LR3 and the wider GH-axis category. Supplied for laboratory research use only; not for human or veterinary use.

- What is GHRP-6?
- GHRP-6 is a synthetic hexapeptide of the growth-hormone-releasing peptide family, with the sequence His-D-Trp-Ala-Trp-D-Phe-Lys-NH2. Its molecular formula is C46H56N12O6 (molecular weight 873.0 g/mol) and it is identified by CAS 87616-84-0. It is also known as SKF-110679. Kovalabs supplies it as a lyophilised powder for laboratory research use only.
- Is GHRP-6 a peptide?
- Yes. GHRP-6 is a synthetic hexapeptide, meaning a peptide built from six amino-acid residues. Its defined sequence is His-D-Trp-Ala-Trp-D-Phe-Lys-NH2, and it is a member of the growth-hormone secretagogue (GHS) family of research peptides. It is supplied as a lyophilised powder strictly as a reference compound for laboratory research.
- Is GHRP-6 legal in the UK?
- GHRP-6 is not a controlled drug under the Misuse of Drugs Act 1971 and it is not a licensed medicine in the UK. Kovalabs supplies it solely as a research chemical for laboratory and in-vitro use, not for human or veterinary consumption. The purchaser is responsible for compliant handling, storage and disposal in their jurisdiction.
- Is GHRP-6 for human use?
- No. GHRP-6 is supplied for laboratory research use only. It is not a licensed medicine, it is not intended for human or veterinary use, and it must not be administered to people or animals. No human application is intended or implied. Please read our research disclaimer before ordering.
- Has GHRP-6 been shown to be safe or effective in humans?
- No. The published literature on GHRP-6 consists of pre-clinical, in-vitro and animal-model research into the growth-hormone secretagogue receptor and ghrelin pathway. None of it establishes a benefit, effect, safety profile or outcome in humans. GHRP-6 is not a licensed medicine and is supplied only as a reference compound for non-clinical laboratory investigation.
- What are the benefits of GHRP-6?
- We cannot describe benefits, because GHRP-6 is a research chemical and not a licensed medicine. The literature investigates it as a ligand of the growth-hormone secretagogue receptor in pre-clinical models only; this does not establish any benefit, effect or outcome in humans. It is supplied for laboratory research use only and is not for human use.
- What is the difference between GHRP-6 and GHRP-2?
- GHRP-6 and GHRP-2 are distinct synthetic peptides within the growth-hormone-releasing peptide family. They differ in amino-acid sequence and identifiers: GHRP-6 is His-D-Trp-Ala-Trp-D-Phe-Lys-NH2 (CAS 87616-84-0). Both are supplied only as research reference compounds, and neither is a licensed medicine or intended for human use.
- What are the molecular identifiers for GHRP-6?
- GHRP-6 has the molecular formula C46H56N12O6 with a molecular weight of 873.0 g/mol. Its CAS number is 87616-84-0, its PubChem CID is 9919153, and its InChIKey is WZHKXNSOCOQYQX-FUAFALNISA-N. The amino-acid sequence is His-D-Trp-Ala-Trp-D-Phe-Lys-NH2. These identifiers are stated on the batch Certificate of Analysis.
- Is all GHRP-6 the same?
- No. Quality varies by supplier and batch. Kovalabs releases each batch only after independent third-party testing, with purity assessed by HPLC at >= 99% and identity confirmed against the expected mass and published identifiers. A batch-specific Certificate of Analysis is available so the material can be verified before use.
- How is GHRP-6 supplied and reconstituted?
- GHRP-6 is supplied as a lyophilised (freeze-dried) white to off-white powder. For laboratory work it is typically reconstituted with a suitable solvent such as bacteriostatic water before use as a reference standard. The mg strength shown is a product specification, not a usage instruction. It is supplied for laboratory research use only.
- How should GHRP-6 be stored?
- Store the lyophilised powder at -20C, kept dry and protected from light. Once reconstituted, hold the material at 2-8C. Proper storage helps preserve peptide integrity for research use. GHRP-6 is supplied for laboratory research use only and is not for human or veterinary use.
- Is a Certificate of Analysis available for GHRP-6?
- Yes. Each batch of GHRP-6 is released with a batch-specific Certificate of Analysis reporting HPLC purity (>= 99%) and identity confirmation against the expected mass. This lets researchers verify the material before use. You can view current Certificates of Analysis on our CoA page.
- Where can I buy GHRP-6 in the UK?
- GHRP-6 can be purchased from Kovalabs for UK despatch as a research chemical. It is supplied as a lyophilised powder with >= 99% HPLC purity and a batch Certificate of Analysis. It is sold for laboratory research use only and is not for human or veterinary use; the purchaser is responsible for compliant use.
- Is GHRP-6 suitable for human use?
- No. GHRP-6 is not supplied for and must not be used for any human application. References in research describe receptor-level activity observed in laboratory and animal-model systems only, and none of it establishes a benefit, effect or outcome in humans. Kovalabs supplies GHRP-6 strictly as a reference compound for non-clinical research.
