Thanks for your feedback. We do the formulations in SF, and we have COAs for our distributors. Typically supplement companies don't tell you who their distributors actually are. Our filter for distributors and manufacturers are purity levels - and you're right, this information is currently not on our site. We've been working hard on meeting customer needs directly as priority first, but we've realized how much communication is lacking. Thanks for bringing attention to what information you'd like to see on our site.
