There are so many brands now in the market, that it's perhaps easier to find a needle in a haystack, than choosing between brands!
Alright. exaggeration aside, one thing that can be safely said is, when after choosing a brand of supplements, you do find that it is working under practical conditions, stick to it, and avoid being adventurous (i don't remember it exactly, but there was a highly-discussed about, simple test done by an enthusiast, on various brands of supplements to test their claims and efficacy, and the result was that many of the brands did indeed fell flat short of their claims! you could search about it on the net; or i would post it here later if required)!
ON (Optimum Nutrition) and Ultimate Nutrition are 2 such brands, which you could stick to (and ON was tested to be effective in that test i wrote of above, IIRC). there indeed may be more, but these 2 names have registered their presence firmly on my mind since long.
