Lab Insights
We shipped temperature loggers with orders from every indexed company. Summer transit told a clear story.
Alongside our purity program, we placed temperature loggers in orders from all twelve indexed companies during peak summer. Three companies’ packages stayed under 25°C throughout transit; four exceeded 40°C for more than six hours.
The correlation with packaging was almost perfect: insulated packaging with cold packs held temperature, padded envelopes did not. Fulfillment scoring now incorporates packaging methodology as a direct input.
Six months, three laboratories, and 20 anonymously purchased samples from 12 companies. Purity ranged from 61% to 99.2% — and two products failed verification entirely.
Special ReportAs legal compounding contracted, demand moved to research-chemical channels. We tracked availability, pricing, and quality across 40 listings.
InvestigationEvery PT-141 product we have tested since 2025 measured under label. The shortfalls cluster suspiciously.
