Melanotan II vs Tadalafil Peptide
A side-by-side research comparison of Melanotan II and Tadalafil Peptide across mechanism, dosing, half-life, benefits, side effects and research status.
Comparison table
| Attribute | Melanotan II | Tadalafil Peptide |
|---|---|---|
| Full name | Melanotan II (MT-II) | Tadalafil-Peptide Conjugate (Experimental) |
| Category | Sexual Health | Sexual Health |
| Status | Research compound | Research compound |
| Mechanism | Non-selective MCR agonist: MC1R produces tanning, MC3R/MC4R increase sexual arousal, MC4R suppresses appetite. Broader receptor activity than PT-141. | CPP moiety facilitates targeted PDE5 inhibitor delivery to penile smooth muscle. Local PDE5 inhibition increases cGMP for NO-mediated vasodilation with reduced systemic exposure. |
| Molecular weight | 1,024 Da | ~2,500 Da (conjugate) |
| Half-life | 2-3 hours | 8-12 hours |
| Bioavailability | High (SubQ) | Targeted (topical/local) |
| Typical dose | 0.25-1 mg | 1-5 mg equivalent |
| Frequency | Loading: daily/EOD · then 2x weekly maintenance | As needed |
| Route | Subcutaneous injection | Topical or local injection |
