GHRP-2 Acetate is supplied as a catalogued research material in 5mg.
The catalogue name specifies an acetate, but it does not establish the number of acetate equivalents or the basis on which the vial amount is stated. Parent and acetate registry records are therefore shown separately and remain conditional on the matching CoA [1,2].
Chemical properties and registry information
| Property | Value |
|---|---|
| Name and synonyms | Pralmorelin, GHRP2, Growth Hormone Releasing Peptide-2, KP-102 |
| Material category | Growth Hormone Secretagogue |
| Sequence | H-D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2 |
| Molecular formula | C45H55N9O6 |
| Average molecular mass | 818.0 g/mol |
| CAS Registry Number | 158861-67-7 |
| PubChem CID | CID 9919153 |
| Structural features | Synthetic hexapeptide containing D-amino acids (D-Ala, D-2-Nal, D-Phe) and a C-terminal amide. Acts as a potent agonist of the ghrelin/growth hormone secretagogue receptor (GHSR). |
| Appearance | White to off-white lyophilised powder |
| Solubility | Soluble in bacteriostatic or sterile water. |
| Physical form | Catalogue vial; exact salt/counter-ion and excipients are batch-specific and must be verified in the CoA and SDS. |
Registry values apply only to the specific molecular entity, sequence, termini and material form. Batch records take precedence over family-level literature identifiers.
A second-generation growth hormone secretagogue (GHS) that stimulates the pituitary gland to release growth hormone. It is more potent than GHRP-6 and has less of an effect on appetite, cortisol, and prolactin levels.
Research background and published evidence
Published research
Pralmorelin/GHRP-2 is described in structural and receptor-pharmacology research as a synthetic growth-hormone secretagogue peptide. This classification supports controlled binding, signalling and analytical-method work; it is not a product-performance statement [1,2].
Current scientific understanding
Published pharmacology or acute endocrine observations do not establish long-term safety, efficacy, dosage, administration, or equivalence for this catalogue batch. Exact stereochemistry, amidation, acetate content and net parent-peptide content require batch evidence.
GHRP-2 is covered by current anti-doping restrictions [3].
Technical comparison
| Aspect | This catalogue material | Comparator |
|---|---|---|
| Identity | GHRP-2 labelled as acetate, with acetate equivalents pending batch confirmation | Free pralmorelin/GHRP-2 parent peptide |
| Structural distinction | Includes acetate counter-ion contribution when the form and stoichiometry match | Parent structure without an assigned acetate equivalent |
| Analytical implication | Verify intact mass, D stereochemistry, C-terminal amide, acetate and net parent content | Parent registry values exclude unverified counter-ion mass |
Quality and testing
Quality information is batch- and presentation-specific. Use only the report linked to the exact size and lot. A report listed for another size, lot or similarly named material must not be treated as evidence for this product.
Chromatographic area purity, identity, net peptide or analyte content, water or counter-ion content, sterility, endotoxin and elemental impurities are different measurements. One result does not establish the others. Only tests supported by a visible, matching report should be regarded as available.
Laboratory handling and storage
Store and handle only under the conditions stated on the product label, batch CoA and SDS. Keep the container secured, correctly identified and protected from contamination. Do not infer storage, solvent compatibility or stability from a related compound.
Laboratory preparation, analytical-method selection, risk assessment, personal protective equipment and waste disposal should follow the applicable SDS and the institution’s approved procedures.
Regulatory and legal status
| Research-use notice | This material is supplied exclusively for laboratory research by qualified professionals and is not intended for human or veterinary use. Purchasers are responsible for compliance with applicable local requirements. |

Frequently Asked Questions
Do the CAS number and PubChem CID apply to every batch form?
Only when the exact sequence or structure, termini, conjugation, salt or counter-ion and hydration state match. The batch CoA and SDS govern; a related-compound identifier must not be substituted.
What does an analytical purity result mean?
It is method- and report-specific. For example, an HPLC area percentage is not automatically the same as identity, net content, sterility, endotoxin status or absence of elemental impurities.
How should the material be stored and handled?
Follow the exact label, batch CoA and SDS together with the institution’s risk assessment. Use only storage and stability information linked to the exact material form and batch.
