anyway, this one comes up when people suddenly look like they spent a month in hawaii after only a few days. it works, sometimes faster than people expect. so let’s split it into the part that’s normal and the part that isn’t, or what people get wrong. first, the tan.
yes, it can come on fast. melanotan 1 (mt1) is a melanocortin receptor agonist, meaning it tells your body to make more melanin, the pigment that makes you tan. it’s not a self-tanner. you still need some uv exposure, even if it’s minimal, for teh process to really kick in.
but it definitely amplifies that response. mt1 is for tanning, full stop. not the libido stuff you hear about with mt2, which is a whole other thing and often gets lumped in. just melanogenesis.
then the logistics. reconstitution is standard: use bacteriostatic water, inject slowly down the side of the vial, don’t shake. store refrigerated once reconstituted. beyond-use dates are typically around 28 days for most peptides once mixed, assuming good sterile technique.
if you’re keeping it for months, you’re looking at degradation, which means less effective product, not necessarily dangerous, but definitely not ideal. people sometimes think they need to bake in the sun for hours for it to work. that’s backwards ime. a little sun goes a long way with mt1.
it’s about stimulating your natural process, not bypassing it. i can’t cite that either but every patient i’ve seen using it says the same thing. graphing the actual skin changes against uv exposure would probably show how fast it hits, something i just eyeballed in a notebook back then.
