Full-panel vs potency-only COA — does it matter?

Yes, and it is one of the sharpest quality signals available. Potency-only testing answers "how strong" — the marketing question. A full panel answers the safety ones: pesticides, heavy metals (hemp pulls metals from soil efficiently — it was literally planted at Chernobyl for that property), microbials, mycotoxins, and residual solvents on extracts. Full panels cost vendors several times more, which is exactly why publishing them separates serious operations from COA theater. Our vendor reviews state which kind each vendor publishes; treat full-panel as a genuine plus, potency-only as the minimum, and neither as optional.
