GHRP-2, Ipamorelin (Blend)

Unlike most GH-secretagogue blends on this platform, this product pairs two peptides that act at the same receptor rather than complementary ones: GHRP-2 and ipamorelin are both ghrelin-receptor (GHS-R1a) agonists, with no separate GHRH-pathway peptide included. The distinction researchers cite between them is selectivity, not mechanism - Raun and colleagues' original ipamorelin characterization specifically measured minimal ACTH, cortisol, and prolactin co-release compared to earlier GHRP-family compounds, while GHRP-2 is documented in the broader secretagogue literature to produce more of that co-release alongside GH. Combining a highly selective GHS-R1a agonist with a less selective one at the same receptor raises a straightforward pharmacological question for study design: whether the two compete for receptor occupancy, produce additive GH release, or whether the less-selective GHRP-2 component dominates the non-GH hormonal effects. Bowers' historical account of GHRP-family development traces this class back to a single shared receptor target, reinforcing that researchers should model this blend as receptor-overlap research rather than assume two peptides automatically mean two independent signaling pathways.

Potential Research Applications: GHS-R1a receptor-occupancy and competitive-binding research Comparative secretagogue-selectivity studies (ACTH/cortisol/prolactin co-release) Additive vs. competitive GH-release research designs GHRP-family receptor pharmacology and historical mechanism research

Peptides.SO currently tracks 2 listings for this blend format, both from USA Peptide Store, at $275.00 and $300.00 depending on format. Single-supplier availability means no cross-supplier price comparison exists yet for this exact combination; researchers running the same receptor-pharmacology comparison can also price the standalone GHRP-2 and ipamorelin listings tracked on this platform and combine defined quantities at the bench, which removes blend-ratio uncertainty entirely.
