UK supplier comparison
Use the filters to pick a size and presentation (vial, pen or serum) and compare like for like, or view every size on a £ per mg basis. Delivery is shown separately because it varies by supplier and order size. Offers whose outbound link failed our last check stay listed but rank below working links.

For in-vitro laboratory research only
GHRP 2 is listed here as a research material. It is not for human or veterinary consumption, and nothing on this page is medical advice or dosing guidance. PeptideCompare is paid by flat supplier fees — never by sales commission or referral — so a price ranks by its number, not by who pays. We do not sell, test or verify any product, and quality or CoA labels are suppliers’ own claims. Always check the final price, documentation and legality with the supplier yourself.
Research profile
About GHRP 2 in the lab
GHRP-2 (pralmorelin) is one of the early synthetic growth-hormone secretagogues. It is used in research on ghrelin-receptor pharmacology and pituitary GH release, and has been used diagnostically in some countries.
Proposed mechanism
Activates GHS-R1a on pituitary somatotrophs and hypothalamic neurons, increasing GH release and amplifying GHRH signalling; it also raises cortisol and prolactin to a degree in models.
Structure note
Synthetic hexapeptide (6 amino acids).
Amino-acid sequence (one-letter)

Typical research themes
- GHS-R1a agonism
- Pituitary GH release
- Secretagogue selectivity
