GHRP-2
An older-generation GH secretagogue — active but less selective than Ipamorelin, rarely chosen in modern clinical protocols.
Definition
GHRP-2 is a six-amino-acid peptide that activates the ghrelin receptor to trigger GH release. It is effective but simultaneously elevates cortisol, prolactin and appetite — the profile Ipamorelin was designed to improve on.
How Meto uses it.
Not part of Meto's catalogue. Included here because members researching older peptide literature frequently encounter it.

Ipamorelin
A selective growth-hormone secretagogue that triggers GH release without spiking cortisol or prolactin — usually paired with CJC-1295.
PeptideGHRP-6
Another older-generation GH secretagogue with strong appetite-stimulating activity — largely superseded by Ipamorelin in clinical use.
PeptideHexarelin
A potent GH secretagogue — more powerful than Ipamorelin but with less selectivity, so less often chosen in modern protocols.
