Looking for high-purity methylene blue? This 1% solution comes in a generous 33.8oz (1000ml) dark amber glass bottle that protects it from light and oxidation. We're talking serious quality here - third-party tested and verified to USP standards, plus tested for heavy metals. Each vertical drop contains 0.5mg of methylene blue trihydrate in demineralized water. And no, it doesn't contain formaldehyde (that's a different compound entirely). Our manufacturing facility is certified for GMP, ISO 22000, and ISO 22716, so you know you're getting pharmaceutical-grade quality. Directions are simple: mix 1ml (about 20 drops) with 200ml of water, or follow your established research protocols. Securely packed in styrofoam for safe delivery.
