afamelanotide (melanotan i) mastery course
Unit 2 of 12
MC1R Biology and Melanocortin Signaling
Receptor biology, downstream signaling, and why selectivity matters.
Why MC1R Matters
This unit treats MC1R as the center of gravity for the afamelanotide story. Without that receptor frame, it is too easy to collapse approved drug use into generic “tanning peptide” language.
Interactive MC1R Map
A quick visual pass across ligand, receptor, signaling, and clinical framing.
mc1r pathway explorer
The Receptor
Where MC1R sits and why a receptor-first explanation matters.
Downstream Signaling
cAMP-linked signaling, melanogenesis, and the course-level takeaways.
Eumelanin Production
Why eumelanin framing is more useful than generic pigmentation language.
Genetic Variation
How MC1R variation complicates simple internet talking points.
