Methylene Blue
Alternative-electron-acceptor dye that supports mitochondrial respiration. Cheap, effective, weirdly under-prescribed. Surprisingly broad use in cognition and cellular bioenergetics protocols.
What it actually is
Not a peptide. Methylene blue is a small-molecule synthetic dye, used as a textile dye since the 1870s and as an FDA-approved drug for methemoglobinemia. At low doses, it acts as a mitochondrial electron carrier — bypassing damaged sections of the electron transport chain to keep ATP production running.
Why peptide users come across it
Popular in the cognitive-enhancement and biohacking community. Often stacked with red light therapy, MOTS-c, or SS-31 for mitochondrial-focused protocols. Real human safety data goes back over 100 years.
