Summary

What dosing, timing, side effects and results do people report with Melanotan I for tanning?

Users describe starting with low daily doses around 0.25-0.5 mg to reduce nausea, then moving to maintenance of 0.5-1 mg on days with UV exposure. Most combine it with brief sun or tanning-bed sessions and report gradual color development with minimal ongoing sides after the first week or two. Several keep a tan for months with infrequent top-up doses. A few note mild flushing or freckles but find the nausea tolerable once the body adjusts.

What this discussion establishesWhere people disagree

Whether a formal loading phase is still necessary or if starting low and only dosing on sun days works just as well.

Still open

How well MT-I works for very fair skin types or how long results truly persist without any UV.

Nothing here is advice.

Got some MT-I coming that I'm planning to use. Chose it instead of MT-II because I want the tanning effect without the appetite loss or boosted sex drive that MT-II causes. Has anyone tried MT-I before? What doses work, when to take it, and what side effects to watch for? Appreciate any input.

Used it last summer with a loading week then 1.2 mg weekly for upkeep until September. The nausea eventually made me stop. A couple months ago I tried 0.35-0.4 mg daily for two weeks then every other day, and now the nausea is only slight and lasts about ten minutes, which feels manageable.

Started at 250 mcg the first week and now use 500 mcg. I get a bit nauseous for about ten minutes and then it passes.

Been wondering what periods of time others have kept their rodents on mt1 and whether they pair that with tanning lamps or actual daylight.

Trying this out this summer just for fun. Broke it into phases: first three days at 0.25 mg twice daily with no UV to get used to it, then four to seven days at 0.5 mg once daily thirty to sixty minutes before five to ten minutes of UV, then from day eight onward 1 mg only on tanning days two or three times a week. Off days no dose. Reconstituted 10 mg with 2 ml BAC water so 0.25 mg is 5 units, 0.5 mg is 10 units, and 1 mg is 20 units.

Just started it for the first time using the same approach I take with MT2: 10 mg spread over twenty days at 0.5 mg daily in the morning. Watch for dark freckles, they aren't dangerous but can affect appearance.

Seen lots of conflicting advice on whether loading is needed. Started at 250 mcg then 500 mcg thirty minutes before sun days and it worked well for a week until the weather turned. Wondering if a two-week load would keep me ready for any decent days. Nausea was mild, just brief cramps that passed by the time I got outside.

Did 1 mg daily with sun exposure for the first two weeks. Now use about half a mg every three days to keep the color. Been tanned for eight months straight.

I've experienced no difficulties whatsoever in Tucson during bright sunny weather.

On it for about a month now. Glad I did the loading because my face flushed badly the first week, but that went away and now no sides at all. Pin 1 mg twice a week and try to get sun on those days. Progress is slow but steady while keeping UV low.

Man, I only recently heard about that pep thing!!

Does this get administered through shots or have folks gone with the nasal option instead? I tried the second one earlier because my skin doesn't darken on its own and I was after something stronger. I'm wondering if people with very fair skin type ever had luck with the first version.
