Quality & Testing

Every lot, verified

A supplement is only worth what's actually in the jar. Here's exactly how we make sure the label and the contents match.

Third-party testing

Every production lot of every Delphi product is sent to an independent, ISO-accredited laboratory before release. The panel covers identity (is it what it says it is), potency (is the dose on the label the dose in the jar), and purity (heavy metals, microbial contamination, and - for our performance line - banned substances).

  • Heavy metals: lead, arsenic, cadmium, mercury - tested to California Prop 65 limits on every lot.
  • Microbiology: total plate count, yeast & mold, E. coli, salmonella.
  • Potency: active ingredients verified against label claim within a 5% tolerance.
  • Banned substances: our performance line is screened against the WADA list, lot by lot.

Manufacturing

All Delphi products are made in the United States in facilities certified for current Good Manufacturing Practices (cGMP) under 21 CFR Part 111, with rolling third-party audits. Blending, encapsulation, and packaging happen under one roof for each product - no contract-handoff roulette.

Sourcing

We name our sources because we chose them on purpose: Creapure creatine monohydrate from Germany, grass-fed dairy from U.S. and New Zealand farms, wild-caught anchovies and sardines from certified sustainable fisheries, and vitamins in their bioactive forms - methylcobalamin, methylfolate, chelated minerals.

What we never use

No artificial colors or dyes. No titanium dioxide. No proprietary blends. No magnesium stearate "fairy dust" beyond functional minimums. If it's in the jar, it's on the label - and there's a reason it's in the jar.
