No independent third-party COA was on file at our last review. Without external lab verification we cannot confirm what is in the vial, and the grade is capped.

When was this Felix Chemical Supply review last updated?
This grade was last reviewed on 2026-07-04 under methodology v1.0.
Competitive pricing, decent US-only shipping and multi-rail payment are the only verifiable strengths; a 2025 domain, a fully gated site, unnamed labs with no openable COA, an unverifiable self-displayed Trustpilot badge, and multiple phishing/low-trust scanner flags sink the trust-critical criteria. Capped no higher than D+ by the missing independent COA.
