@bfuller I have heard different protocols for this. How frequently are you doing it?

I’m not trying to stir things up. This is an honest question from a relatively new person to this group. I looked at Puratek’s website after reading the previous posts. All the COA’s that I looked at are from Freedom or ILS, neither of which have a good reputation here. Do we trust the COA’s because it would be expensive to buy multiple vials of a product and test them myself. Or, does everyone test each product they purchase?

@Commander Amazon has them. I haven’t bought one yet but it’s in my cart.
