Consistent purity, fast domestic ship

[DEMO REVIEW — remove] Ordered from ERP twice; both batches tested 99%+ on Janoshik and shipping was about 6 days domestic. Responsive on their channel.

Purity, test dates, and compound names shown here are the same facts published on each public certificate page — aggregated, never edited. A high pass rate reflects the batches that were tested; it is not a guarantee of every order. Browse the COA corpus →
