The most was with a brand called LipoVida -- but I literally wanted to vomit ever day that I took them. Plus I heard that 80 HCA wasn't actually legal or possible (I'm not an attorney or a doctorscientist, so don't quote me on that - just passing along what I heard) The best so far for actual weight loss for me plus no nausea has been Pure GCE (I ordered mine through the site 'bestgarciniacambogiapills' dot com.
Again, if you don't mind the jitters and all that jazz, it may be worth your time to check out the LipoVida brand. Otherwise, Pure GCE gets my vote. Good product except the product isn't the best.
