How MT-II is used, and why the confidence is misplaced
This unit explains, for education only, the routes of administration and the entire published human dose record, so you can read community discussion of MT-II critically. It is not a protocol, a dose, or a recommendation, and MT-II is not approved for human use.
The honest throughline is that confident online dosing numbers rest on almost no controlled human data. This unit prints no schedule and no worked dose calculation, precisely so you can see how little evidence sits beneath the certainty.
Key terms
The routes people use
MT-II is used by two main routes in the real world, and they differ enormously in how well they are understood. Subcutaneous injection is the only route ever used in clinical studies; the nasal spray that dominates social media has essentially no published clinical data behind it.
The irony is sharp: the most popular route is the least understood. No published human study has measured MT-II exposure from a nasal product, and every chemical analysis in this literature tested vials rather than sprays, so a spray delivers an unknown amount of an unexamined product. Australian consumer journalism, last updated 11 March 2025, reported tanning nasal sprays with illegal ingredients openly advertised and sold online there, at around $100 a bottle, with a TGA spokesperson quoted saying every form of these products carries significant health risks. Any confident nasal-spray protocol is certainty the evidence cannot support.
This unit is education only and not medical advice. Nothing here is a protocol or a recommendation to use Melanotan II by any route.
