coffee
FLOW Medium Roast
Only brand that publicly shares lab results for mycotoxins, pesticides, and mold at every supply chain stage. Tested 65% higher in antioxidants than 46 other brands.
Quality & Materials
USDA Organic, specialty-grade beans. Tested for 400+ contaminants.
Evidence & Testing
Public COAs at every stage. Antioxidant content independently verified.
Brand Transparency
Lab results published. Supply chain traceable.
Value Assessment
$23/12oz ($1.93/oz). Premium but justified by testing transparency.
Why Not Alternatives?
Bulletproof claims 'mycotoxin-free' but doesn't publish lab results. Most specialty coffee is fine, but Purity proves it with testing. Mycotoxin concern is mostly marketing, but if you care, this is the only transparent option.
