Melanotan 1: The Safer Tanning Peptide Nobody Talks About
Alright, you guys asked for it let's talk about Melanotan 1 (MT1), also known as Afamelanotide. This is MT2's less famous sibling, and honestly, it might be the smarter choice for most people who just want a tan. RESEARCH and EDUCATION PURPOSES ONLY, NOT MEDICAL ADVICE. What MT1 Actually Is Melanotan 1 is a synthetic analog of alpha-melanocyte stimulating hormone (ฮฑ-MSH), just like MT2. Both were developed at the University of Arizona in the same research program. The key difference? MT1 is a LINEAR peptide while MT2 is CYCLIC. That structural difference matters. A lot. MT1 is what we call a "selective" melanocortin receptor agonist. It primarily hits MC1R - the receptor responsible for melanin production. It has minimal activity at MC3R, MC4R, and MC5R compared to MT2. Translation: MT1 gives you the tanning effect without most of the other effects that come with MT2. MT1 vs MT2: The Key Differences MT1 (Afamelanotide): - Selective MC1R agonist - Primarily tanning effects - Minimal appetite suppression - Minimal sexual effects - Generally better side effect profile - Shorter half-life (requires more frequent dosing) - Actually FDA approved in Europe and Australia for specific conditions - More expensive per dose MT2: - Non-selective melanocortin agonist - Tanning + appetite suppression + sexual effects - More side effects (nausea, flushing) - Longer half-life (less frequent dosing) - Not FDA approved anywhere - Cheaper per dose - More "bang for your buck" if you want multiple effects The Effects People Actually Experience Tanning: This is what MT1 does, and it does it well. You'll notice gradual darkening of skin, darkening of existing moles and freckles, and a more even tan compared to UV exposure alone. The effect builds over time and is dose-dependent. What You WON'T Get: - Significant appetite suppression (maybe very mild, but nothing like MT2) - Sexual effects (minimal to none) - The intense nausea that MT2 can cause
