Quality & Testing
At Eternal Elixir, quality is not a marketing claim — it is the foundation of everything we do. Every supplement we produce meets the highest standards of purity, potency, and safety.
Independent Lab Testing
Our Methylene Blue has been tested by an independent laboratory. Contract Testing Laboratories of America (CTLA) tested lot 2025022801, confirmed its methylene blue identity by HPLC, and measured arsenic, cadmium, mercury and lead using USP <233> methods. View the certificate of analysis.
This is the only certificate of analysis we publish at the moment. For any other product, email info@eternalelixir.com with the product name and the lot number on your bottle, and we will tell you what testing documentation we can share.
GMP Certified Manufacturing
Our supplements are manufactured in GMP (Good Manufacturing Practice) certified facilities. This means every step — from raw material receipt to final packaging — follows strict quality control protocols, documented procedures, and regular audits.
Ingredient Sourcing
We source ingredients based on three criteria: purity, bioavailability, and evidence. We use pharmaceutical-grade and USP-grade ingredients where available, standardized extracts with verified active compound concentrations, and bioavailability-optimized forms.
Transparent Dosing
We do not use proprietary blends. Every product label lists the exact dose of every active ingredient per serving. You know exactly what you are taking and how much.
Independently Owned & Operated
Eternal Elixir is proudly independently owned and operated. Our U.S. company address is 30 N Gould St, Ste N, Sheridan, WY 82801 USA. We handle customer support directly — no outsourced call centers, no automated responses.
