GHRP-6 is a synthetic growth-hormone-releasing hexapeptide studied in research into ghrelin and GHS-receptor signalling within GH-axis models.
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.
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.
Every batch is released only after independent third-party analysis. Purity is assessed by HPLC at >= 99%, and identity is confirmed by HPLC retention-time matching (HPLC-RTM) against a reference standard 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.
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.
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.

Easy, straight forward, well priced
great quality and an impressive service. Used many times. Wouldn't go anywhere else.
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.
Most transparent provider in the UK
I’ve been using kovalabs for a few weeks but before my first order I did a LOT of research, and chose these as they are by far the most transparent and stringent provider in the UK, by a country mile. This is now my 4th order, and every single time without fail the communication is outstanding, the quality is as expected - superb. And prices remain highly competitive especially for the assurance you’re getting high quality, tested products. I’ve recommended to everyone I know.
100% the best peptide company I've dealt with for peps.This company stands behind it's products and it's service quite boldly, and understandably so. The products themselves look amazing and very professional, and the quality is far beyond what I’ve had from any other pep company in the uk. On my last order, I did have an issue with Royal Mail, in which I then emailed customer support, and Sophie put it right for me on the exact same day, very impressed. They've earned a repeat customer from me!
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
I'm so glad I found this supplier. Honest people, everything verified, and customer service is amazing. I would even give them more stars if I could. First class
Very impressed
Great service, first time using Kovalabs. Feels like a very personal service. Well done to Taylor. Would highly recommend 👌
Excellent service and products consistently. I highly recommend. Have tried a lot of peptide products and companies and kovalabs is the best by far!
