Methylene Blue
Redox-active phenothiazine compound · encapsulated research materials
Methylene blue (methylthioninium chloride) is a heterocyclic aromatic phenothiazine compound and a classic redox-active dye. It is a small molecule — not a peptide — supplied in capsule form as a reference material for laboratory use.
Research context
In published literature, methylene blue is studied in the context of mitochondrial electron-transport, redox-cycling, and cellular-bioenergetics research using in-vitro and preclinical models. Glow Peptides supplies Methylene Blue strictly as a reference material for such in-vitro and preclinical research. It is not a therapeutic product and is not for human or veterinary use.
Handling & storage
Methylene Blue is supplied in capsule form as a research reference material. General laboratory handling practice for encapsulated materials of this type:
- Storage: keep capsules sealed in a cool, dry place away from light and humidity; refrigeration extends shelf life.
- No reconstitution: encapsulated reference materials are handled as supplied — there is no solvent or reconstitution step.
- Documentation: record the lot number and its Certificate of Analysis for your records.
Quality & testing
Every lot of Methylene Blue we supply is independently tested at a U.S. laboratory and ships with a lot-specific Certificate of Analysis. Testing includes HPLC with UV detection for purity and mass spectrometry for identity, with our purity standard at ≥99%.
You can search any lot and view its documentation on our Quality & COA verification page, and learn what the numbers mean in how to read a Certificate of Analysis. Our published customer rating is 4.5 on Trustpilot.
Methylene Blue is available as an independently tested, ≥99%-purity research reference material with a per-lot Certificate of Analysis.

Is Methylene Blue intended for human use?
No. Methylene Blue is supplied strictly as a reference material for in-vitro laboratory and preclinical research. It is not a drug or supplement and is not for human or veterinary use.
How is Methylene Blue tested for purity?
Each lot is independently tested at a U.S. laboratory by HPLC with UV detection (purity) and mass spectrometry (identity), and ships with a lot-specific Certificate of Analysis. Our purity standard is ≥99%.
How should Methylene Blue be stored?
Keep capsules sealed in a cool, dry place away from light and humidity; refrigeration extends shelf life. Encapsulated materials need no reconstitution.
