About Methylene Blue
Methylene blue is an old redox dye and FDA-approved drug (a small molecule, not a peptide) sourced in research for mitochondrial and nootropic studies. It ships as a solution or powder, and pharmaceutical grade matters because industrial dye grades carry contaminants.
Its reported half-life is ~5–6.5 hours, which is the main reason the community cadence above looks the way it does. FDA-approved for drug-induced methemoglobinemia and ifosfamide-induced encephalopathy.

- COA status and purity — The 1 COA-backed Methylene Blue Nasal Spray listing shows assayed purity and test date so quality is a number, not a claim.
- Stock status — Live in-stock state for each Methylene Blue Nasal Spray listing, refreshed on a recurring basis.
Reading Methylene Blue Nasal Spray Listings
Nasal spray listings are ranked on total Methylene Blue per bottle, so a lower-priced bottle at a lower concentration can still be the more expensive option per milligram. Where a vendor publishes it, the mcg or mg delivered per spray is what determines how many doses a bottle actually contains.
A nasal spray COA should confirm the active ingredient's purity, and — where available — the preservative system and pH range, which do not appear on a vial COA. Intranasal delivery differs from injection in absorption kinetics, so vial protocols do not carry over.
