GHRP-2 10mg

Description

Description & Mechanism

GHRP-2 is a synthetic hexapeptide belonging to the class of growth hormone secretagogues, widely utilised in biochemical and physiological research to study receptor-mediated signalling within the hypothalamic–pituitary axis. It functions primarily as an agonist of the growth hormone secretagogue receptor (GHS-R1a), a G-protein-coupled receptor expressed in both central and peripheral tissues.

In cellular and in vivo research systems, GHRP-2 activates GHS-R1a independently of endogenous growth hormone-releasing hormone (GHRH), leading to downstream intracellular signalling cascades involving calcium mobilisation and modulation of second messenger pathways. These effects make GHRP-2 a useful molecular tool for investigating receptor activation dynamics, neuroendocrine regulation, and peptide–receptor interactions.

In preclinical research settings, exposure to GHRP-2 has been associated with altered signalling along the hypothalamic–pituitary axis, with downstream effects dependent on experimental model, dose, and exposure conditions. As such, GHRP-2 is commonly employed in mechanistic studies exploring peptide hormone signalling and receptor pharmacology.

Applications in Research

• As a molecular probe to study growth hormone secretagogue receptor (GHS-R1a) activation
• Investigation of neuroendocrine signalling pathways within the hypothalamic–pituitary axis
• In cell-based assays examining GPCR-mediated signal transduction and calcium flux
• In animal or ex vivo experimental models for mechanistic studies of peptide hormone signalling
• As a reference compound in receptor binding, agonist profiling, and structure–activity studies

Specifications Summary

Handling, Reconstitution & Stability

• Weigh under dry conditions; peptide is hygroscopic
• Reconstitute in sterile water or appropriate buffered aqueous solution depending on assay requirements.
• Filter sterilize if required (e.g. 0.22 µm) immediately prior to use.
• Aliquot reconstituted solutions and store at –20 °C or below to minimise degradation
  Avoid repeated freeze–thaw cycles.
• Inspect for precipitation or pH changes prior to use in sensitive assays.

Precautions & Notes

• GHRP-2 activity is concentration-dependent; appropriate dose–response controls are recommended.
• Peptide stability may be influenced by pH, temperature, and prolonged aqueous exposure..
• Light and elevated temperatures may contribute to degradation; store under protective conditions.
