GHRP-2 (CAS 158861-67-7) is a synthetic hexapeptide supplied as a lyophilized powder (≥98% HPLC purity) in 5 mg or 10 mg research vials — NOT for use in humans or veterinary medicine. GHRP-2 can be studied in vitro within a laboratory to examine peptide/receptor interactions and growth hormone signalling pathways (C45H55N9O6, MW 817.97 g/mol). Experimental studies indicate that GHRP-2 demonstrates rapid clearance in laboratory models (t1/2 ~0.55 hours), thereby aiding research studies utilizing animal models. Research applications of GHRP-2 include evaluation of its secretagogue effects (increase GH secretion) on pituitary cells in which the GHRH receptor is bypassed. (Chemical book, Science)

Composition and Technical Information

GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide (sequence D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH₂) with the following chemical structure: C₄₅H₅₅N₉O₆; mol. wt. = 817.97 g/mol. It is packaged in sterile vials containing ≥98% pure lyophilized peptide powder, with < 1 EU/mg endotoxin levels, ≤ 5% acetic acid (acetic acid), TFA ≤ 0.1%, and ≤ 6% of water. The material should be stored between 2 and 8 degrees C (refrigerated) for the duration of this study.

Research Focus Areas

GHRP-2 is widely studied in laboratory and animal models for the following areas of research:

  • Growth Hormone Release: Investigated for its ability to stimulate endogenous growth hormone secretion via ghrelin receptor (GHSR-1a) activation.
  • Endocrine Signalling: Explored for its interaction with multiple hormonal pathways involved in growth hormone regulation.
  • Metabolic Research: Studied in models examining energy balance, glucose metabolism, and nutrient utilisation.
  • Appetite Regulation Studies: Evaluated for its influence on pathways related to hunger signalling and feeding behaviour.

 

Its interaction with ghrelin receptors makes GHRP-2 valuable for studying growth hormone release, metabolic processes, and appetite-related signalling pathways.

Quality and Handling Information

GHRP-2 is produced in a controlled environment and has an HPLC purity of ≥98% and an amino acid analysis peptide content of ≥95%. Each lyophilized vial containing the GHRP-2 is sealed to prevent contamination, and they are stability is maintained during refrigerated transport and storage.

Store the product in the refrigerator between 2°C-8°C, or at -20°C for extended storage (greater than two years) while keeping away from light and moisture. Sterile handling and minimizing freeze-thaw cycles will help maintain the activity of this product.

Quality specifications are set to control experimental variables (e.g., TFA ≤0.1% and water ≤6%). The verified purity gives researchers the ability to develop accurate experimental concentration parameters when using GHRP2 in research.

Safety & Compliance Notice

GHRP-2 has not been approved by the MHRA for human, clinical, or veterinary use and is strictly for research use only (RUO). The MHRA warns that misuse of the compound may result in serious negative effects from improperly using GHRP-2, such as insulin dysregulation. All buyers should adhere to local laws, as improper handling of the compound will nullify their study or research.

Laboratory biosafety protocols must be followed by all researchers. The benefits of GHRP-2 and the dosage of GHRP-2 are strictly defined as being for research purposes.

Frequently asked questions

Is GHRP-2 intended for human use?

No. This is intended solely for research in laboratories and cannot be used as a drug, dietary supplement, or consumable product.

What kind of molecule is it?

It is a hexapeptide synthesis which works as an agonist in growth hormone secretagogue receptor in laboratory conditions.

How is purity confirmed?

The purity can be determined via HPLC, whereas identity can be validated via LC-MS. Both of these numbers must be included on the Lot Specific Certificate of Analysis

Why does a batch COA matter?

Lot specific COA will relate the analytical information to your particular lot, which is necessary for proper research and reporting.

How should the peptide be stored?

Frozen lyophilized powder storage is recommended, as well as keeping solutions refrigerated and protected from light with limited freeze-thaw cycles.

Can results be compared across studies?

The comparison can be done only if purity, receptor system, and assay conditions are the same, which is the reason for using traceable and well-characterised products.

Technical specifications

The GHRP-2 research peptide is for use in the laboratory environment under controlled scientific study conditions. Prior to using this product in experiments, researchers must carefully check both the product label and the relevant batch documents.
