I wanted to make these public because I've been meaning to check on the "safe" ranges for the substances listed but have just been too damn busy with school. Maybe someone already knows, or will pursue this more vigorously.
Honestly, I'm just happy that this provider supplied me a detailed COA at all... it seems like too much to ask of many these days.
Also, I really don't know much about heavy metal contamination over long periods of time, but if the only thing these guys are testing for is heavy metal content under 20ppm, that means that a sample could contain 19ppm and it would receive a "pass." Correct me if i'm wrong, but ingesting 19ppm of heavy metals on a daily basis sounds like a no-no.
