You can’t expect your body to function optimally with sub-optimal fuel and inadequate recovery methods. For years, fitness fanatics have relied on their standard BCAAs to bring them back to life after a gruelling workout, but according to research, there’s a far more effective recovery solution. Studies have found that while BCAAs can stimulate 22% more muscle protein synthesis than a placebo, complementing them with EAAs has 50% better muscle protein synthesis than BCAAs alone. This over-engineered recovery formula harnesses the extensively researched benefits of a range of trademarked ingredients to bring you the ultimate BCAAs and EAAs blend. To optimise muscle protein synthesis, muscle growth, strength and recovery, a generous dose of clinically-substantiated EAAs and additional BCAAs have been added to the formula. As a pre-digested form of protein, EAAs boast a fast absorption rate, which may result in more efficient results and reduced downtime. To help lower cortisol levels and boost testosterone, endurance, strength and your muscle recovery rate, the game-changing and clinically-proven ingredient, KSM-66 Ashwagandha has also been included. To support hydration, nerve function, muscle contraction and nutrient uptake to promote faster recovery, Sustain has been loaded with electrolytes and minerals. To complete this killer formula, AstraGin™ has been added to further enhance the absorption of amino acids by up to 43%, improve ATP by 18% and increase insulin sensitivity by 38%.
If you’re not willing to settle for average results, you shouldn’t settle for mediocre supplements either. With Limitless Laboratories plant-based, full-spectrum amino acid blend, you can rest assured that you’re receiving a formula that will work as hard as you do. Loaded with EAAs, BCAAs, electrolytes, minerals, KSM-66 Ashwagandha, AstraGin and more, what more could you possibly want from an advanced recovery formula? fortifying combination of ingredients that work synergistically to promote rapid absorption and anti-catabolic properties.
