I had the capsules previously discovered in a health food store and informed me ausgibig about dosage and mode of action of the product. Unfortunately me the price was too high. Wodrauf way I researched on the internet and am been able to find on Amazon. This product I could, compared to the health food store and also from a different vendor, actually save here more than 50%, had to pay shipping and the goods have been delivered ratzfatz! I can not say much, but quality is right on the mode of action. Strong buy recommendation on this supplier !!!
