BioHack Track models Methylene Blue at a half-life of 6 hours, so every dose you log is decayed against that curve and the app shows estimated active levels — not just what you typed.
No FDA-approved product for this compound is cited on this page, and no approved human dose is quoted. Treat the range below as research and community practice rather than a prescribed dose.
Pharmaceutical-grade liquid or capsules; dosing precision matters since it's active across a wide range.
Store away from light.
Serious risk of serotonin syndrome if combined with SSRIs/SNRIs/MAOIs — this interaction is well documented and dangerous. Only use pharmaceutical-grade (not aquarium/industrial-grade) product.
Track Methylene Blue in BioHack Track. Half-life, dose range and route come pre-filled from this library — log a dose and the app counts your vial down, models what is in your system, and puts it on the same chart as your labs and body composition.
These open a search of each database for Methylene Blue — they are not citations, and nothing here is evidence for any particular dose. The same links are in the app.
The half-life, route and dose range on this page are compiled from published pharmacokinetic literature, manufacturer and product monographs where one exists, and the ranges commonly reported in clinical and research use. They are kept as a range rather than a single figure because that is what the sources actually support — a half-life varies with route, formulation and the person.
These are not citations, and this page is not a review of the evidence. Where a number matters to you, follow the database links above and read the source. We say so plainly rather than dressing a compiled reference up as one.
Nothing on this page has been reviewed by a named clinician. It is a reference for people already tracking a protocol, not a recommendation to start one.
General reference compiled for use inside the app, not medical advice and not a recommendation to take anything. Dose ranges are what is commonly discussed, not a prescription. Talk to a qualified healthcare professional.
