Oh I don't have DMSA, and never had it. I only have ALA. Someone in the freq dose group mentioned supersmart was one place you could get it but I don't know whether she'd ordered any from there or just found it on the net. When I looked it up it was a lot cheaper than Captomer from the Nutricentre, so I recommended it to you. Plus you get a 5% discount from supersmart if you join their membership scheme.
I couldn't find any other sources but there may well be. It would be good to find somewhere that delivers on time!
Sorry if I gave you the wrong impression. I hope it arrives soon and is a good quality one!
