Trust Index breakdown

DerivedV3

The Trust Index weighs five evidence pillars — purity claims-vs-reality, testing transparency, enforcement conduct, operational accountability and reputation integrity — into a single 0–100 factor. Nothing here can be bought.

Provisional — Insufficient Data. This listing is under review; the Trust Index is withheld until verification completes. A precise number is withheld rather than guessed — absence of evidence is never shown as a low score.

Despite 'research purposes only' labeling, the FDA found evidence from the company's website and YouTube channel that the products were intended for human use (weight loss). The company was required to notify FDA of corrective steps within 15 working days.

Cross-vendor price ranking is intentionally not computed

The Trust Index rates each vendor against a fixed evidence rubric — it never ranks vendors against each otheror sorts the directory. Naming a “best-value” vendor per compound would require exactly that cross-vendor sort, so we don’t. Compare the cited price-per-mg in the Products & price table yourself, or open a side-by-side comparison.
