Generally speaking many or most plants could have some metals in them. This is because plants are able to take these up into them from the soil and water etc. So this is largely dependent on your source of raw materials and their attention to detail during extraction process and their pre shipment testing (which all companies should be doing).
This is the data you see on the COA.
We do test from time to time. Our source has been the same for 11 years and so far we have yet to see even 1 quality control issue.
Basically everything comes from CHina so its important to have a strong supplier.
If you are buying random stuff off of alibaba or ebay etc, then I would be suspect of everything.
Even stuff on amazon these days because MANY of the vendors just search alibaba and buy the cheapest stuff they can find then list on amazon for a markup.
We have one of the best sources possible. VERY confident. Since day 1 we have always used our own raws to ensure quality. Most companies will just call their manufacturer and tell them what they want and the manufacturer will then source the cheapest stuff available. We have raws delivered to manufacturer direct so we know whats in our products.
Also for everyone reading this we will have hand sanitizer available probably tomorrow morning.
Only have about 1000 units but at least itll be enough to help some people get what they need.
