Meraki Blu USP Methylene Blue 150mg
“Methylene blue: the dye that dyed your urine blue before it dyed your biohacker feed.”
6/10Trust Score
72%Confidence
Meraki lists at $35 (discounted from a suspicious $89 'regular' price) for a 30ml bottle containing 150mg USP-grade methylene blue. Other retailers like Underground Nutrition NJ list the same Meraki product at $39.99. Raw USP methylene blue powder from chemical suppliers costs a fraction of this, but finished, tested, dosed liquid products in this range are fairly standard. The inflated anchor price is a red flag; the actual $35 price point is reasonable for the category.
🚩 Red Flags
- Pricing is confusing — listed as '$35 sale' from '$89 regular,' a classic inflated-anchor trick. [source]
- Some customers report poor customer service: delayed responses and difficulty getting refunds. [source]
- Some resellers label it 'for laboratory and research purposes only' — signals regulatory grey area. [source]
✅ Green Flags
- USP pharmaceutical-grade, 99.9% purity, third-party tested for heavy metals and impurities. [source]
- Comes with a 30-Day Money Back Guarantee per at least one major retail partner. [source]
- Consistently high customer ratings (~4.8–5 stars) across multiple independent platforms. [source]
- Made in the USA, sold through multiple established third-party wellness retailers. [source]
Why We Said HOLD
Your interest in methylene blue for cognitive support is genuinely valid — it has decades of medical use and emerging mitochondrial research behind it, making it one of the more scientifically interesting nootropics out there. Meraki appears to be a legitimate US-based brand offering USP-grade, third-party tested product with solid ratings. The hold here is about value and context: methylene blue as a dietary supplement sits in a regulatory grey zone (some resellers quietly label it 'for research use only'), and the clinical dosing for cognitive benefits in healthy adults is still being worked out. The $89 regular price is almost certainly inflated to make the $35 sale price look dramatic — a pricing tactic that should give you pause. If you're going to try methylene blue, the quality markers here are real, but shop around: comparable USP-grade products exist at similar or lower prices.
