Order came in fast without issues. Everything so far has been top notch. Read a lot of reviews trying to cross reference different reviews from different sources. Super happy I went with IDUN, no one wants to waste time and money and effort.

Great customer service!

Quite easily the smoothest operation I’ve worked with so far. 3rd party linked COAs that take you right to the 3rd party’s page to verify testing. Very good packaging, both aesthetically and shipping practices. Fast shipping. Labels, batch # and QR codes on each bottle. Printed COAs in the box. Competitive pricing on most items. But I’ll gladly pay for the verifiable quality and service. 10/10 amazing company to work with.
