I'm hoping these guys are good to deal with/quality as they've got some pretty good deals (namely the only dostinex I can afford!). I've used AG and liked them. And, i've used some other called CTD and I didn't notice anything with their letro- had to order from AG before I was even half through with their product. And when I tried AG's, it tasted different, looked different and actually seems to be working. So, thumbs up for AG's quality and service.
