Look for a product with a COA that’s up-to-date and comes from a reputable third-party lab. Check that what’s listed on the COA matches up with the company’s product description, and that the lab has performed contaminant testing.
We recommend looking for results for heavy metals, molds, and pesticides. If the company uses a solvent-based extraction method, it’s also a good idea to check for residual solvent testing results.
