Product description
Blupreme supplies USP pharmaceutical-grade methylene blue as a dry powder in sealed packaging. It is not a prepared solution, and no liquid is added.
Powder format
The product is supplied in dry form rather than pre-mixed with water. The stated pack weight of 10 g is the net weight of the powder contents, not the combined weight of the powder and packaging. Blupreme powder is available in packs of various sizes. View available sizes and current prices in the product catalog.
Composition
USP pharmaceutical-grade methylene blue powder without added water or a liquid carrier.
Sealed, batch-labelled packaging
Each pack is sealed and labelled with batch information. Use the batch number shown on the packaging to locate the corresponding quality documentation.
Quality testing
The material is tested against the full applicable USP-NF monograph specification. Testing covers identity, assay, Azure B and other organic impurities, residual solvents, elemental impurities, residue on ignition, microbial limits, and bacterial endotoxins.
Certificate of analysis
Batch-specific certificates of analysis provide the reported test results for the material in each batch. View available certificates and supporting documentation on our Quality Testing page.
Storage and handling
Keep the package tightly closed, dry, and protected from light. Open and handle the powder carefully to limit dust and staining. Follow the product label and safety data sheet when handling the product.
Why full USP-NF testing matters
Many other sellers test only for heavy metals and claim compliance with USP-NF grade, which is misleading. Blupreme evaluates the material against the full applicable specification, including identity, assay, impurity, solvent, elemental, microbiological, and endotoxin requirements.
Frequently Asked Questions
What does USP-grade methylene blue mean?
USP–NF is a recognised pharmaceutical quality standard. A supported USP-grade claim requires compliance with all applicable monograph and general requirements, including identity, assay, organic impurities, and other relevant quality controls, not only a heavy-metal screening panel.
Can I review information about Blupreme’s quality testing?
Yes. The Quality Testing page explains the tests performed, the applicable specifications, and what the results demonstrate.
What is a certificate of analysis?
A certificate of analysis, or COA, is a batch-specific laboratory document. It identifies the tested material, batch number, quality specifications, test results, and whether the batch met the stated requirements.
Do you sell to individual customers?
Yes. We sell to both individual customers and businesses.
