Wessells et al. (JAMA 2000) 20 men, psychogenic ED 0.025–0.1mg/kg SC 80% at 0.1mg/kg Placebo (10%) MC4R activation sufficient for penetration-grade erection in 80% of psychogenic ED cases MT-2 works when the p…
Melanotan-2 (MT-2) MC4R receptor agonist in hypothalamus; central arousal pathway activation Psychogenic erectile dysfunction, hypoactive sexual desire disorder 30–90 minutes post-injection 60–72% improvement …
Direct comparison trials reveal where MT-2 outperforms PDE5 inhibitors and where it doesn't. The 2003 European Urology study tested both compounds in sequence: participants received sildenafil 100mg on demand …
Melanotan-2 Central MC4R activation → oxytocin/NO release in hypothalamus and spinal autonomic nuclei 60–120 min (SC), 2–4 hrs (intranasal) 24–72 hours Psychogenic ED, central arousal deficits, low libido Best…

Melanotan-2 (MT-II) MC1R/MC4R agonist. Direct receptor activation Bypasses UV damage, highly potent (nanomolar range), predictable dosing, isolates melanogenesis pathway Systemic effects in vivo (appetite supp…
Lyophilised (unreconstituted) −20°C (freezer) 25°C (room temp) 24–36 months 12–18 months Light exposure accelerates oxidation. Store in original amber vial or foil-wrapped Reconstituted in bacteriostatic water…
Primary Mechanism MC4R/MC3R receptor agonism (central + peripheral) PDE5 inhibition (peripheral vasodilation only) MT-II's dual-pathway action addresses both arousal and blood flow, making it potentially effec…
In vitro melanocyte culture 10–100 nM (10–100 µg/mL) 48–72 hours Sustained with repeated dosing No keratinocyte or immune cell interaction Ex vivo human skin explant 50–200 µg/cm² topical or 0.1–0.5 mg subderm…
Unreconstituted powder, freezer -20°C (-4°F) 12-24 months 95%+ purity maintained Optimal long-term storage; standard for research-grade peptides Unreconstituted powder, refrigerator 2-8°C (36-46°F) 3-6 months …
The storage requirements for Melanotan-2 change completely at the point of reconstitution, and understanding this distinction prevents the most common protocol failures we see in research settings. Unreconstit…
Selective melanocortin agonists exist. Compounds like THIQ (MC4R-selective) or BMS-470539 (MC1R-selective). But they serve different experimental purposes than MT-2. Selective agonists answer 'which receptor m…
Compared to related peptides such as CJC-1295 or Tesamorelin, Melanotan 2 exhibits a more immediate onset of action in pigmentation pathways due to its direct receptor interactions. While peptides like CJC-129…

Melanotan-2 is often compared to Melanotan-1 (afamelanotide), its linear analog, and to PT-141 (bremelanotide), a cyclic derivative. Each peptide differs in receptor selectivity, duration of action, and intend…
To make this all crystal clear, we've put together a simple table summarizing the storage protocols. Our team uses this as a quick reference, and we think you'll find it helpful. Room Temperature Lyophilized P…
It’s impossible to have a complete conversation about how Melanotan 2 works without bringing its sibling, Melanotan 1, into the picture. While they share a name and a common goal, their mechanisms and profiles…
