- | Peptide Variant | Primary Mechanism | Hunger Signaling Potency | Half-Life | Storage Stability (Reconstituted) | Best Application | Bottom Line ||—|—|—|—|—|—|| GHRP-6 Acetate | GHS-R1a agonist (hypothalamic) | 94% food intake increase vs baseline | ~2.5 hours | 28 days at 2–8°C | Primary hunger pathway research, appetite stimulation studies | Most potent orexigenic peptide; gold standard for ghrelin receptor investigations || GHRP-2 Acetate | GHS-R1a agonist (reduced calcium signaling) | 41% food intake increase vs baseline | ~2.0 hours | 28 days at 2–8°C | Growth hormone studies where appetite is secondary endpoint | Moderate appetite effect; inferior to GHRP-6 for hunger-specific models || Hexarelin | Mixed GHS-R1a/CD36 agonist | 23% food intake increase vs baseline | ~1.5 hours | 21 days at 2–8°C | Cardiovascular research | Weak appetite stimulation; not recommended for hunger studies || Ipamorelin | Selective GH secretagogue (minimal GHS-R1a) | <10% food intake increase vs baseli
