What Is GHRP-2? A Research Primer

GHRP-2 is a synthetic growth-hormone-releasing peptide in the ghrelin-receptor agonist class. Sold for laboratory research use only.

GHRP-2 (growth-hormone-releasing peptide 2, also called pralmorelin) is a synthetic peptide that acts as a growth-hormone secretagogue by binding the ghrelin receptor (GHS-R). It is sold as a research-use-only reference compound.

What makes GHRP-2 distinct

As a ghrelin-receptor agonist, GHRP-2 belongs to a different pharmacological class from GHRH analogs such as CJC-1295 or sermorelin. It is structurally related to GHRP-6 and hexarelin, and vendors often list it next to a GHRH analog.

Research-use status

  • Pharmacological class: ghrelin receptor (GHS-R) agonist
  • Published literature is mostly animal and early clinical work
  • Sold for laboratory research use only; this page does not summarise effects or uses

COA and verification considerations

Because research compounds are unregulated, the certificate of analysis is the single most important thing to check. For GHRP-2, a trustworthy COA names the testing laboratory, reports HPLC purity (typically 99% or higher), confirms identity by mass spectrometry, and, for injectable-format material, includes endotoxin and sterility results. A batch or lot number that matches the product, a recent test date, and a working verification portal are strong positive signals.

What to check before buying

  • Is a named third-party lab shown, not just a claim of testing?
  • Does the COA lot number match the batch you are buying, with a recent date?
  • Are purity and identity both reported, ideally with endotoxin and sterility?
  • How does the vendor rank on our published, testing-led formula?

Frequently Asked Questions

How is GHRP-2 different from CJC-1295?

GHRP-2 works through the ghrelin receptor as a secretagogue, while CJC-1295 is a GHRH analog. They belong to different pharmacological classes and vendors often list them together.

What should a GHRP-2 COA show?

A named third-party lab, HPLC purity (99%+), and mass-spec identity confirmation, plus endotoxin and sterility data for injectable research material.

Does affiliate status change the ranking?

No. Rankings follow our published methodology only.
