- Adamax Peptide
- Selective ghrelin receptor agonist
- GHS-R1a
- 2–4 hours
- Appetite stimulation, GH release, metabolic studies
- Best for isolating ghrelin signaling without native ghrelin's rapid degradation
- Native Ghrelin
- Endogenous orexigenic hormone
- GHS-R1a (requires acylation)
- ~30 minutes
- Physiological appetite and GH studies
- Rapidly degraded; difficult to maintain stable receptor occupancy
- GHRP-6
- Growth hormone secretagogue
- GHS-R1a + non-selective
- 1–2 hours
- GH secretion, appetite (less selective)
- Broader receptor activity; useful for GH studies but less appetite-specific
- Ipamorelin
- Selective GH secretagogue
- GHS-R1a (GH-selective)
- ~2 hours
- GH release with minimal appetite effect
- Preferred when GH secretion is the endpoint without confounding appetite changes
- MK-677 (Ibutamoren)
- Long-acting GH secretagogue
- 24 hours
- Chronic GH elevation, lean mass studies
- Oral bioavailability; mimics ghrelin but with sustained receptor activation
- Adamax peptide fills a specific niche: it provides the appetite-stimulating and GH-releasing effects of ghrelin with the extended half-life needed for controlled experimental protocols. Native ghrelin's 30-minute half-life requires continuous infusion to maintain receptor occupancy, complicating study design. GHRP-6 and ipamorelin prioritize GH release with variable effects on appetite. Ipamorelin, in particular, shows minimal orexigenic activity despite robust GH secretion, making it unsuitable for appetite-focused studies. MK-677 offers the longest duration of action and oral bioavailability, but its 24-hour half-life eliminates the pulsatile GH secretion pattern that many neuroendocrine studies aim to preserve. Adamax peptide's 2–4 hour half-life strikes the balance between experimental manageability and physiological relevance.
