Hello, last summer was my first using melanotan 2, and I think the stuff is great. I literally still have slight tan lines and the last time I got real sun exposure / used m2 was early September! I just started dosing again in expectation of tanning soon since we're now entering may. My issue is a friend of mine has cancer and requires a liver transplant and many of our friends are going to visit the Dr and get screened to find a match for living donor. They simply remove a part of your liver and the rest supposedly grows back. When reading about the criteria for being a living donor there is mention that consuming illegal substances could disqualify you from being a donor. I assume they mean cocaine, heroine and the like, but do you think M2 use could be disqualifying? What if I'm a match in every way but the doctor is very strict and won't allow me? Should I even disclose the fact that i'm taking it? Thanks.
