Available sizes: 5 mg, 10 mg
A second-generation secretagogue
GHRP-2 is a synthetic hexapeptide acting at GHS-R1a. It belongs to the generation of growth hormone releasing peptides developed after GHRP-6, with greater potency at the target receptor and noticeably less of the appetite effect.
Where the off-target activity is the subject
Its reported cortisol and prolactin release is a confound in studies of growth hormone, and a topic in its own right in studies of how the secretagogue receptor interacts with other pituitary axes. Which of those a researcher is doing determines whether GHRP-2 is the right compound or the wrong one.

Read alongside
GHRP-6 is the first-generation compound and Ipamorelin the selective one; the three together are the standard series for structure-activity comparison in this class.
Documentation and verification
Certificates of Analysis are published for tested products and batches. A certificate is a batch-specific record: it reports what was measured, by which method, on a stated date, against a batch identifier. It is evidence about the sample analysed at the time of analysis, and it is silent on attributes it does not list and on what has happened to the material since.
The batch number is the field that connects the document to a physical vial. Where the identifier on a vial does not appear on a certificate, the certificate does not describe that vial, however thorough the analysis behind it was. Batch records can be searched directly, and the guides below explain what each field establishes and what it does not.
