No complaint about the merchant; arrived promptly and well packaged.As for the product, not effective. I tried the recommended 2 pills per day to as high as 12 pills per day without any effect. Suggest that the placebo affect may be operating here, and that the power of suggestion is more effective than the actual caps. Consider that if this product were all that powerful, the drug companies would long ago have patented the pill, put it on the prescription list, and be charging $25 a pill. You would pay it too, if it really worked.Doesn't, and not worth your time, or the even the inexpensive charge for the bottle.
