Don was very nice but I had a very bad reaction and when I called today to get a refund because I thought as with any other product you order on the market they guarantee their product 100% apparently you guys only guarantee is 50% and I want to tell you that I only bought it because you said it was safe to take if I open the capsule and I know you meant well but I had a very bad reaction and my doctor and looking at the bottle said there was things on there that should've been realize that you don't put that down your esophagus also he was a little bit taken back by the fact that you didn't have an expiration date he thought that was very odd and I know you explained your reasoning but he said that was a very contrived way in his mind of just never having an expiration date he suggested I return it and I only Took two and had a horrible experience so I would like 100% full refund
