GHRP-2
Coming soonPralmorelinSynthetic hexapeptide, D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2, also called pralmorelin. A growth hormone-releasing peptide that acts at the growth hormone secretagogue receptor, studied for its receptor pharmacology.
Supplied as a single-chamber lyophilized vial with a colour-coded cap (Muscle Growth).
Research literature, not dosing or treatment instructions.
- A drug profile describes pralmorelin as a synthetic growth hormone-releasing peptide from a series developed at Tulane University and Polygen. (PMID 15230633)
- The receptor targeted by growth hormone secretagogues was cloned from pituitary and hypothalamus of swine and humans. (PMID 8688086)

Questions about GHRP-2
How much published research is there on GHRP-2?
The research library's PubMed search for GHRP-2 returned 237 records on 5 October 2026, 21 of them reviews. The library lists 4 studies chosen for what they measured. ClinicalTrials.gov lists no registered study naming GHRP-2 (checked 5 October 2026).
Is GHRP-2 an approved medicine?
No medicinal product containing GHRP-2 is listed in Drugs@FDA (checked 5 October 2026), and the research material we supply is not a medicine. It is supplied for in-vitro laboratory research only, not for human or veterinary use.
Is GHRP-2 the same as pralmorelin?
Yes. GHRP-2 is also called pralmorelin and KP-102. A drug profile describes it as a synthetic growth hormone-releasing peptide from a series developed at Tulane University and Polygen (PMID 15230633).
How does GHRP-2 differ from Ipamorelin?
Ipamorelin and GHRP-2 are both synthetic growth hormone secretagogues acting at the growth hormone secretagogue receptor. Ipamorelin is a pentapeptide and GHRP-2 a hexapeptide.
How is the identity of GHRP-2 confirmed on a certificate?
A research-grade certificate of analysis typically reports identity by mass spectrometry and purity by HPLC. The mass result is read against the average molecular weight of 817.9 Da listed on this page. The research library's guide to reading a certificate explains each field.
What other names is GHRP-2 published under?
GHRP-2 is also written Pralmorelin and KP-102. The catalog lists it under the name GHRP-2.
Is this product for human use?
No. Peptency products are supplied for in-vitro research only. Not for human or veterinary use, not for diagnosis or therapy.

Published work includes a drug profile and diagnostic stimulation-test studies. We supply GHRP-2 as a lyophilized vial for in-vitro laboratory research only.
What are the chemical identifiers of GHRP-2?
GHRP-2 has the molecular formula C45H55N9O6, an average molecular weight of 817.9 Da and CAS number 158861-67-7.
Chemistry checked against PubChem (CID 6918245), 5 October 2026; full chemistry record in the research library.
What does published research on GHRP-2 cover?
A PubMed search for GHRP-2 returned 237 records on 5 October 2026, 21 of them reviews. Our research library lists 4 of these studies, chosen for what they measured.
- A drug profile describes pralmorelin as a synthetic growth hormone-releasing peptide from a series developed at Tulane University and Polygen. (Review, Drugs R D, 2004; PMID 15230633)
- The receptor targeted by growth hormone secretagogues was cloned from pituitary and hypothalamus of swine and humans. (Howard et al., Science, 1996; PMID 8688086)
Mechanism, every cited study and the regulator records are on the GHRP-2 page of the research library. Papers are listed by what they measured, not as evidence of any use.
How is GHRP-2 supplied and stored?
GHRP-2 is supplied as a lyophilized (freeze-dried) powder in a sealed vial, for in-vitro laboratory research only. Our stated storage condition for the sealed lyophilized vial is 2 to 8 °C. The label and the lot certificate carry the lot-specific storage condition and expiry date.
What is the regulatory status of GHRP-2?
Drugs@FDA lists no application naming pralmorelin as an active ingredient (checked 5 October 2026).
The WADA 2026 Prohibited List names this substance under S2.2.4. A WADA entry is a sporting rule, not a statement about legality outside sport.
A regulator record is information about a database entry. It is not advice and not a statement that any use is lawful or unlawful in any country. How regulators approach research peptides.
