Not all methylene blue is created equal.

Most methylene blue on the market is industrial-grade, untested, or just caffeine in disguise. Here's why ours is built differently.

Worth the price

Lab results came back showing real improvement in my mitochondrial markers. The pharmaceutical-grade matters.

Dr. James R.MD · Practicing 18 years

Stack-friendly

I take 10mg every morning alongside NMN. Cognitive performance noticeably sharper by week 2. This is the real deal.

No more 3pm crash

Coffee always wrecked me by mid-afternoon. With Simpyl I get sustained clarity. Sleep has actually improved too.

Sarah K.Verified buyer · Triathlete

Precision matters

I was skeptical about MB until I read the testing reports. 99%+ purity is not what you get from generic capsules.

David P.Biochem researcher

Daily ritual

Took me 3 weeks to feel the full effect. Now I won't go a day without it. Cleaner energy than I've had in years.

Athlete approved

Recovery times improved measurably. Heart rate variability up 18% over 8 weeks. Hard data, not vibes.

Compounding effects

Started with 5mg, moved to 10mg. The mental clarity stacks over time. Best decision I've made for my brain.

FAQ

The questions we get asked.

Straight answers about methylene blue, our formulations, and how to use them.

Methylene blue is a phenothiazine compound first synthesized in 1876. At low pharmaceutical doses, it acts as an electron donor in the mitochondrial electron transport chain, supporting cellular energy production without the crash profile of stimulants.

Most users report noticeable mental clarity within 30 to 60 minutes of their first dose. Sustained energy and focus benefits compound over 2 to 3 weeks of daily use as your mitochondrial efficiency adapts.

At our precision 10mg daily dose, methylene blue has an excellent safety profile. It sits well below the threshold where any pro-oxidant effects emerge. We recommend pairing with morning protocols and avoiding combination with SSRIs.

Yes. Simpyl is designed to stack cleanly with NMN, NAD+ precursors, creatine, and most clean-stack essentials. Avoid combining with serotonergic medications without consulting a physician.

Free shipping on orders over $40, dispatched within 24 hours from our cGMP facility in the United States. Try it for 30 days. If you don't feel the difference, send it back for a full refund.

Most methylene blue sold online is industrial or aquarium grade. It's uncontrolled for purity, heavy metals, and contaminants. Ours is USP pharmaceutical-grade (>99% purity) with third-party testing on every batch. The data is on the label.
