Three Pack! - Methylene Blue USP Grade 2oz Bottle Dropper

✨ Pure and Safe: USP Grade Methylene Blue — 2oz Liquid Drops, 3-Pack

NeuroBlue Methylene Blue Liquid Drops, now in a 3-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 3-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.

🧴 Three 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, one on the go, and one in reserve.

🔬 Precise, Reliable Dosing: Every 1mL (20 drops) delivers 10mg of 1% Methylene Blue — about 0.5mg per drop. Three 2oz bottles provide roughly 177mL combined — a long-lasting supply split across three individually sealed containers.

🌱 Easy Clean-up: Spills happen — lift stains fast with lemon juice, lime juice, or ascorbic acid.

Why choose the 3-pack? Three 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.
