✨ Pure and Safe: USP Grade Methylene Blue — 2oz Liquid Drops, Twin Pack (2 x 2oz)
NeuroBlue Methylene Blue Liquid Drops, now in a twin pack of our original 2oz bottles — USP pharmaceutical-grade, third-party lab-tested Methylene Blue with extra supply on hand. Made in the USA in a facility held to the highest quality standards, so you know exactly what you're getting, every drop.
✨ Maximum Purity: UV-verified at 99.9–100.4% purity — the same pharmaceutical-grade quality in every bottle of this twin pack.
🇺🇸 Made in the USA: Manufactured domestically with a proven track record of strength and consistency — about 85% of our customers come back for more.
🔒 Heavy Metal Free: Independently tested and certified free of heavy metals.
🔒 Formaldehyde Free: No formaldehyde, no harsh preservatives, no fillers — just clean, simple formulation.
🧴 Two 2oz Amber Glass Bottles: Each bottle is 2 fl oz (59mL) amber glass with its own built-in dropper — perfect for keeping one at home and one on the go.
🔬 Precise, Reliable Dosing: Every 1mL (20 drops) delivers 10mg of 1% Methylene Blue — about 0.5mg per drop. Two 2oz bottles provide roughly 118mL combined — a long-lasting supply split across two individually sealed containers.
🌱 Easy Clean-up: Spills happen — lift stains fast with lemon juice, lime juice, or ascorbic acid.
Why choose the twin pack? Two individually sealed 2oz bottles mean fresher use with less exposure per bottle once opened, a backup always on hand, and better value per mL than buying single bottles separately.
