That's really strange. I haven't noticed any tolerance, I get erections, flushing after each dose, and dark tan after every dose. I haven't used melanotan 2 for 5 years though. Only about a year with a few month pauses. Maybe try to cycle it? Like use it for a month and then stop for 2-3 weeks. You shouldn't lose much tan over this time.
