Ive only had the sample sizes from CL so I cant comment on effectiveness but the green mag taste delicious, and I have seen great reviews on their product, you will surley be much happier than with the BSN products (especially in the wallet)
As for the Universal products, I am running their "Big Picture Stack" (Shock Therapy, Intra-Aid, and Torrent) in a sponsored log now, you should check out the log if these products interest you, I am only in week 1.5 now so I don't have a solid opinion yet, but the products are certainly showing to be effective so far, and the torrent taste absolutely incredible.
