Common questions
- What purity is Methylene Blue, and how is it tested?
- Methylene Blue is supplied at 99%+ purity. Each production lot is tested by an independent third-party laboratory, with HPLC for purity and mass spectrometry for identity. Published certificates can be looked up by the lot number printed on your vial in our COA library.
- Does Methylene Blue come with a Certificate of Analysis?
- Certificates are published online rather than printed in the box. You can view and download the certificate on this page before you buy, and match the lot number on your vial to its certificate in the COA library. Our guide on how to read a peptide COA explains each section.
- How fast does Methylene Blue ship?
- Orders placed before 2 PM EST ship the same day from the United States, with tracking and discreet packaging.
- How should Methylene Blue be stored?
- Store in a cool, dry place away from light. Our storage and handling guide covers temperature, light and moisture in more detail.
- What if independent testing doesn't confirm the stated purity?
- Our Purity Guarantee covers it: if independent testing does not confirm the stated purity, you get a full refund and a free replacement.
- Is Methylene Blue for human use?
- No. Methylene Blue is sold strictly for laboratory research use only. It is not for human or veterinary use, and we do not provide dosing or administration guidance.
