I would frequently buy bulk powders and pills from amazon and other onlineshops to save some money vs. the pricier pharmacy brands.
The problem is that there is zero control for quality or even lab analyses that would show the actual content of the product. I suspect that many of the powders I have bought didn't actually contain the active ingredient. This isn't the case with the expensive brands such as Thorne and others. What are your experiences with this?
