FAQ
- What is GHRP-2 and how does it work in research?
- GHRP-2 is a synthetic hexapeptide (MW ~818 g/mol, CAS 158861-67-7) that binds the ghrelin receptor (GHSR), prompting pituitary growth hormone release; it is studied as a growth hormone secretagogue for laboratory research only.
- Is GHRP-2 FDA-approved or legal for research use?
- GHRP-2 is not FDA-approved. Japan permits it narrowly as a diagnostic agent (pralmorelin) for GH deficiency testing. It remains investigational in the US and is banned by WADA under class S2 at all times.
- How is lyophilized GHRP-2 reconstituted for laboratory use?
- Add bacteriostatic water to the lyophilized vial; working concentration (mg/mL) equals mg of peptide divided by mL of water added. Example: 5 mg + 2 mL = 2.5 mg/mL. Follow aseptic technique per laboratory protocol.
