Rated 1 out of 5 by from Who knows if it works?? I am the swallower of many daily vitamins and supplements. Never! I have I seen such a large pill. I literally almost choked trying to get it down. Sadly, only a life-saving surrum would warrant my desire to try a pill this size ever again.

Rated 5 out of 5 by from superior amino 2222 This is the best amino supplement I have found but because of the size of the pill I have to cut it up into smaller pieces which is no problem at all to do.

Rated 5 out of 5 by from good product I take these daily. Unable to do strenuous exercise do to an operation, I have found they make short periods of exercise more productive and seemed to contribute to my general well being. Although large, I found them easy to swallow.

Rated 5 out of 5 by from Super Energiser I have been taking amino acids for muscle building for years. I tried Optimum Nutrition brand. This product contains high quantiites of essential aminos often not found in other brands. It is also very good value. 2 caps before training gives noticeable muscle pump and two caps after training noticeably improves recovery and muscle growth.

Rated 4 out of 5 by from Good for All, Vegan or Not I am a strict vegetarian; although, complete protein comes from animal products. This does contain whey. My blood panel reading shows normal protein levels while I eat no meat or fish; and, eat no cheese or drink milk. An amino Acid pill(s) does the trick for me. I'm not a bodybuilder, just health conscious.
