Two recent clinical trials have shown that a synergistic combination of Zinc Monomethionine Aspartate, Magnesium Aspartate, and Vitamin B₆ can significantly increase anabolic hormone levels and muscle strength in well-trained athletes. The novel Zinc Monomethionine Aspartate formula may also help to increase endurance, healing, growth and restful sleep.

Optimum Nutrition's After Max™ is a comprehensive post-workout powder that establishes a foundation for accelerated recovery and serious muscle growth. This state-of-the-art recovery formula supplies a superior blend of 40 grams of the highest quality proteins, with rapidly digesting carbohydrates, free form amino acids and 22 vitamins and essential minerals including antioxidants and electrolytes.

What you eat, when you eat it, and how much you ear has a dramatic effect on your performance. But, not all nutrient combinations work equally well. Our 2:1:1 Recovery is based on the latest science demonstrating that blending different types of carbs and proteins maximizes absorption and leads to better results than the use of larger amounts of any single type.

Research published in the Journal of Applied Physiology and other peer reviewed publications has shown that HMB may have an effect on increasing muscle weight and strength. Three grams of HMB per day can help highly trained muscles combat protein breakdown, assist in muscle repair and support increased endurance.

Whereas proteins helps with muscle rebuilding, carbs refuel and replenish. Of the various types available, Waxy Maize Starch and Trehalose are two of the best. Waizy maize starches are long-chain, highly-branched, exceptionally-dense complex carbohydrates that are rapidly absorbed. Trehalose is a much smaller, slower-digesting molecule comprised of two unusually linked glucose sugars.
