GHRP-6 is a growth hormone secretagogue hexapeptide used in controlled in-vitro studies of ghrelin/secretagogue receptor (GHSR-1a) signalling, including Gq/PLC/IP3/Ca2+ pathways and downstream assay readouts under non-clinical laboratory conditions.
GHRP-6
This cyclic amide hexapeptide (sequence: His–D-Trp–Ala–Trp–D-Phe–Lys-NH2) is commonly selected to explore receptor engagement, second-messenger dynamics, and structure–activity relationships within the GH axis in model systems.
For laboratory research only. Not for human use.

Handling & storage
- Storage (dry): Keep vials protected from light and moisture.
- Reconstitution: Bring vial and diluent to room temperature. Reconstitute with
Bacteriostatic Water 10 ml. Swirl gently — do not vortex. - After reconstitution: Store at 2–8 °C, protect from light, use aliquots to reduce handling, and avoid repeated temperature cycling.
- Compatibility: Use only within research protocols that follow your lab’s SOPs and local regulations.

About GHRP-6 in research
Researchers use GHRP-6 to probe GHSR-1a receptor engagement, map second-messenger responses (e.g., PLC/IP3/Ca2+), and characterise structure–activity relationships in cell-based assays. These studies focus on receptor pharmacology and pathway modelling exclusively in controlled, non-clinical in-vitro environments.
Synthesis & quality
Manufactured via controlled, validated peptide-synthesis processes to deliver high purity and lot-to-lot consistency. Each batch undergoes identity, purity, and appearance checks before release.
Legal & safety
XL Peptides supplies materials strictly for laboratory research. Products are not medications, foods, supplements, or cosmetics; not for human or veterinary use. By purchasing, you confirm you are a qualified researcher and will handle the material in line with your institution’s policies and applicable laws.
FAQs
What is GHRP-6?
A hexapeptide growth hormone secretagogue used to study ghrelin/secretagogue receptor (GHSR-1a) signalling and related assay readouts in vitro.
How should I store the peptide?
Keep lyophilised vials away from light and moisture. After reconstitution, store at 2–8 °C, protect from light, and avoid repeated temperature cycling.
What diluent should I use?
