Description
Methylene Blue is a phenothiazine dye, and Pure Rawz sells it as capsules, tablets, a liquid and a powder. It’s tested to 99% purity or higher and sold strictly for lab research.
Methylene Blue explained
Methylene blue is a phenothiazine dye first made in 1876. It accepts and donates electrons, and at low concentrations it can feed electrons into the mitochondrial chain.
It’s an approved drug for methemoglobinemia.
How it works
At low levels, methylene blue accepts electrons from NADH and passes them to cytochrome c, helping mitochondria make ATP when the normal chain is impaired. It also inhibits monoamine oxidase A.
At higher levels, its effects flip, so the dose range used in a study matters.
Methylene Blue research
Rojas and colleagues reviewed its neuroprotective effects in 2012.
Its dye properties make it a common lab stain.
The primary literature is on PubMed. Here’s a search to start from.
Options and prices
It comes in 7 options. Pick one from the dropdown above the cart button:
- Capsules, 20mg per capsule/60ct/1200mg: $46.36
- Capsules, 20mg per capsule/120ct/2400mg: $92.72
- Tablets, 20mg per tablet/60ct/1200mg: $46.36
- Tablets, 20mg per tablet/120ct/2400mg: $92.72
- Liquid, 17mg per ml/60ml/1g: $38.63
- Powder, 2g: $77.27
- Powder, 5g: $193.17
Capsules hold a measured amount each, listed in the size option with the count and total.
Each tablet holds the same measured amount, which the size option spells out.
The liquid comes in a glass dropper bottle at a stated concentration per mL, so every draw is easy to calculate.
The powder is the bulk form, for labs that weigh their own amounts. Use a milligram scale for accuracy.
Study design notes
Cognition studies often test a compound in a deficit model, for example after sleep loss, stress or a drug that impairs memory, because effects are easier to see there than in healthy animals.
Start with the smallest size to confirm solubility and handling, then scale up once the protocol is set.
Test a range of amounts if you can. Many cognition compounds have an inverted-U response, where too much works worse than a moderate amount.
Measuring the liquid
At 17mg per mL, every 1mL holds 17mg and every 0.1mL holds 1.7mg. A graduated 1mL dropper or syringe makes those measures accurate.

How we test each batch
We test each batch for identity and purity before it ships, using HPLC and mass spectrometry, with independent third-party checks on top of our own.
The batch number on the label matches the certificate of analysis. If your lab keeps paperwork on file, ask us for it and we’ll email it over.
How to store Methylene Blue
Keep the container sealed at room temperature, away from heat, moisture and sunlight. Keep the bottle capped, upright and out of direct sunlight at room temperature unless the label says otherwise.
Label the container with the opening date. It saves guesswork later.
Safe handling
Treat it as a lab chemical. Gloves and safety glasses are the minimum, and a clean, uncluttered workspace cuts down on mix-ups.
Store prepared solutions apart from untouched stock, and record who mixed what and when.
What you’ll need
- a graduated 1mL dropper or syringe for accurate volumes
- a milligram scale, since powder has to be weighed
- a suitable solvent if you’re making your own solution, such as DMSO or propylene glycol
Often ordered alongside
- Phenylpiracetam Hydrazide: Phenylpiracetam hydrazide, also sold as fonturacetam hydrazide, is phenylpiracetam with the amide group swapped for a hydrazide.
- L-Theanine: L-theanine is an amino acid found mainly in tea leaves.
- GTS-21 HCl: GTS-21 (DMXB-A) is a partial agonist at alpha7 nicotinic acetylcholine receptors.
- Phenibut FAA: Phenibut (beta-phenyl-GABA) is GABA with a phenyl ring added, which lets it cross into the brain.
- Piracetam: Piracetam (2-oxo-1-pyrrolidineacetamide) was the first racetam, made by UCB in Belgium in the 1960s.
