I ordered 10- AD30. Honestly I was skeptical after placing my order and going to Reddit. Not having done this before, I did not know what to expect. I was happily reassured when I received my order. It was very quick shipping, I ordered Thursday night and it arrived Monday afternoon from essentially across the country. As far as quality, online searches also got me a little apprehensive before trying, but I'm a happy camper. I'm not going to speak to authenticity of it being Rx. However, I like it better than the Rx 20mg IR (Epic Pharma) and 10mg IR (North Star) I'm prescribed. 3/10 used so far and they have all been consistent. I will likely use this vendor again if the need arises to fill Rx gaps. I highly recommend them, at least for the product I tried.
