Melanotan II & Looksmaxxing:
Clavicular's Tanning Peptide
Melanotan II is the melanocortin agonist in Clavicular's Ascension Stack — driving UV-independent skin darkening, appetite synergy with Retatrutide, and the full-body aesthetic transformation Clav documented publicly.
Quick Answer: What Is Melanotan II?
Melanocortin agonist
Classification
121062-08-6
CAS Number
Melanogenesis (skin darkening)
Primary Effect
Melanotan II is a synthetic analog of alpha-melanocyte stimulating hormone (α-MSH). By activating melanocortin receptors (MC1R, MC3R, MC4R, MC5R), it stimulates melanin production independent of UV exposure — producing a lasting tan while simultaneously activating appetite-suppressing pathways that synergize with Retatrutide.
Why Clavicular Uses Melanotan II
Clavicular's looksmaxxing protocol isn't just about fat loss and muscle — it's about the complete aesthetic package. While Retatrutide handles body recomposition and BPC-157 + TB-500 handle recovery, Melanotan II addresses one of the most visible markers of physical attractiveness: skin color and tone.
In his publicly discussed protocol, Clavicular uses MT-II to achieve a dark, even tan without extensive sun exposure. This is particularly valuable in winter months or when training schedules don't allow for consistent outdoor time. The compound drives melanogenesis at the cellular level — producing melanin regardless of UV stimulus.
There's also a functional synergy with Retatrutide. MT-II activates MC4R (melanocortin-4 receptor), which is the same receptor targeted by several appetite-suppressing pathways. This creates an additive appetite suppression effect when stacked with Retatrutide's GLP-1/GIP/glucagon triple-agonism — accelerating the fat loss phase.
How Melanotan II Works: Mechanism
Stimulates melanin (eumelanin) synthesis — the primary tanning mechanism. Produces dark, UV-independent pigmentation.
Energy homeostasis, appetite modulation, adipogenesis. Contributes to the metabolic effects of the compound.
Primary appetite suppressor in the CNS. Activation reduces food intake, synergizes with GLP-1 signaling from Retatrutide.
Sebaceous gland regulation. Affects sebum production — relevant for skin health and acne management in the looksmaxxing context.
Research Dosing Parameters
Loading Phase
0.25–0.5mg subcutaneous, daily
Continue until desired tan level achieved. Typically 10–14 days.
Maintenance Phase
0.5–1mg, 2–3× per week
Maintain tan with intermittent dosing and UV exposure.
Half-Life
~1 hour (short acting)
Peak effects occur rapidly. Pigmentation persists for weeks.
Route
Subcutaneous injection
Reconstituted peptide, subcutaneous administration for research.
Research use only. These are published research protocol parameters, not medical dosing recommendations. MT-II is not FDA-approved for human use. Consult a healthcare professional.
MT-II + Retatrutide: The Synergy
The combination of Melanotan II and Retatrutide represents one of the most compelling compound pairings in the Ascension Stack from a mechanistic standpoint. Here's why they work together:
Dual MC4R Activation
Both MT-II (direct MC4R agonist) and GLP-1 signaling from Retatrutide converge on hypothalamic appetite suppression circuits. The additive effect can produce stronger appetite suppression than either alone.
Aesthetic Completeness
Retatrutide drives body fat down while MT-II darkens the skin — two of the most visible aesthetic markers simultaneously optimized.
Metabolic Synergy
MC3R activation from MT-II affects energy homeostasis and adipogenesis, potentially complementing Retatrutide's glucagon-driven fat oxidation.
Timing Compatibility
MT-II's short half-life (~1 hour) and Retatrutide's weekly dosing schedule have no pharmacokinetic interactions — they can be used safely in the same protocol.
MT-II vs GHK-Cu: Complementary Skin Peptides
Clavicular's Ascension Stack uses both MT-II and GHK-Cu for skin — but they do completely different things:
| Feature | Melanotan II | GHK-Cu |
|---|---|---|
| Primary Effect | Melanin production (tanning) | Collagen/elastin synthesis |
| Mechanism | MC1R agonist | TGF-β, VEGF, antioxidant activation |
| Appearance Benefit | Darker skin tone | Smoother, firmer skin texture |
| Available at ClavTides | External source | ✓ GHK-Cu 50mg — $50 |
| Used Together? | Yes — complementary effects | Yes — different skin targets |
Sourcing Melanotan II
Melanotan II is not currently stocked at Clav Tides, as it falls outside the primary research peptide categories. However, it's widely available from specialized research peptide vendors.
When sourcing MT-II for research purposes, verify:
- HPLC certificate of analysis showing ≥98% purity
- Mass spectrometry confirmation of molecular weight (1024.18 g/mol)
- Lyophilized powder form (not pre-mixed solutions)
- US-based vendor with clear research-only terms
For the rest of the Ascension Stack — Retatrutide, BPC-157, GHK-Cu, IGF-1 LR3, NAD+, TB-500, CJC-1295/Ipamorelin — these are all available at Clav Tides with third-party COAs.
