If you are looking for some cheap DMSA, then I recommend this site.

You'll have to break the caps open, which is really annoying, but I found this stuff was MUCH cheaper than getting it compounded. There are other sites that sell this brand of DMSA in the 25mg, so you might be able to find a website cheaper.

You also have the option of ordering from this website. They will make DMSA in any dose you want at a very reasonable price.

When I start into DMSA and ALA I'll be ordering from that company instead.
