Creatine has been repeatedly shown to increase muscle size and strength gains during resistance training. There is a great interest among researchers to find methods to further augment these gains by combining other supplements with creatine that may be complementary. One of these supplements is beta-alanine, which is the preferred precursor for the synthesis of carnosine in muscle. Carnosine serves as buffer in muscle to help the muscle better deal with acid that is produced during intense exercise. This study examined the combined effects of both creatine and beta-alanine during resistance training. Three groups of healthy strength athletes were randomized into a placebo group, a creatine group, or a Creatine + Beta-Alanine group. All groups performed a 10 week resistance training program followed by testing of maximal strength and body composition. The combination group experienced the greatest increases in lean body mass and the greatest reduction in percent body fat. Both creatine groups had greater increases in strength compared to placebo. This study is important because it shows an additional benefit of supplementing with Beta-Alanine beyond that achieved with Creatine supplementation alone.

I have been using a creatine/beta-alanine stack now for 2 weeks and have already noticed a significant change in my workouts. I noticed the buffering effect because I do not feel the fatigue after a 2 to 2 1/2 hour work out of weight training. My strength has increased and I have already noticed my waistline is getting smaller and my ab are more toned. This is a great combination. I am 66 years old and have excellent muscle tone and size. I have been using ProSource products for about 4 years now and will continue to do so. Thank You for your outstanding products. Sincerely Alfred Alvarez
