CarnoSyn® beta-alanine is important for carnosine synthesis. Beta-alanine is a pre-cursor to carnosine. It joins with the amino acid histidine, through a peptide bond to form carnosine in the muscle. Muscle carnosine is the major buffering agent, or neutralizer, of hydronium ions that lead to muscle fatigue and failure. By increasing the amount of carnosine in the muscle, CarnoSyn® beta-alanine both increases an athlete’s peak performance and speeds muscle recovery.

Ultra-Durance™ also contains a proprietary blend of vitamins and minerals that work in conjunction with the beta-alanine to reduce lactic acid by up to 18% in clinical trials. Ultra-Durance™ is free from all artificial flavours, colours, sweeteners and preservatives.

  • Contains the clinically researched dose of beta-alanine (1.7grams)
  • All Beta-alanine has been shown in research to increase muscle carnosine (has been shown to be rate limiting amino acid (BA)
  • 18% reduction in lactid acid levels (resulting in % increase in aerobic threshold – failure)
  • Can train more intense (before failing) for longer periods after 12 weeks presumably due to less stress generated from exercise (great plateau buster)
  • Reductions in harmful by-products from muscle damage during training (over training), less soreness, more energy (especially during playing/training)
  • Does not cause muscle mass increase on it’s own *great for weight class athletes/iron men competitors (diet alterations can aid muscle gain and be an optimal additive for any supplement system. If you train, this is for you)
  • Endurance athletes and bodybuilders alike with like the idea of doing less damage from training (more gains, whatever the type)
  • Mineral complex to aid hydration in body at all times
  • All natural, no artificial flavours, colours, preservatives, binders or fillers
  • All ingredients are in compliance for IOC, NCAA, NFL, NBA, NHL and MLB. Every single batch of Ultra-Durance™ is tested for banned substances by the world class sports doping control laboratories.

How To Use

Add 1 scoop to 8oz -12 oz (250 ml-375ml) of water depending on your flavour preference. Shake for 10 seconds. Ultra-Durance™ can also be added to your morning Pharma-Greens or your morning  and evening protein shake for convenience.  It takes 10 days for Ultra-Durance™ to fully load in your system.  To ensure the maximum benefits, Ultra-Durance™ must be taken continuously during heavy training blocks and leading up to a race.

When To Use

If you train 5 to 6 times per week, take 2 scoops daily, 1 scoop in the morning and 1 scoop in the evening, with or without food.

Five to seven days before a race increase your dosage to 4 scoops a day, 2 scoops in the morning and 2 scoops in the evening (or 2 in the morning, 1 at lunch and 1 before bed). Continue this 4 scoop regime for 2-3 days after your race then drop back down to 2 scoops daily.

  1. Armand P

    Ultra-Durance by F2C was the first product of this type (CarnoSyn Beta-Alanine) that I’ve ever used. I like the idea of what this product is meant to do. As an older athlete, anything to help quicken muscle recovery and help push a little harder and longer in races and workouts sounded great to me. There is also some studies showing the benefits of a great source of beta-alanine, so this isn’t a placebo effect. I take this with my Pharma-Greens in the morning and again at night before bed.

    This product attracted my attention because I am always looking for something that can help improve my performance and speed my recovery at the same time reducing lactic acid. This is huge for race day when I load pre-race 3-times a day before race and day after. It causes a tingling/prickling feeling in most for about 15-20 minutes which I like, but if you don’t you can mix it with carbs. I mix it with Pharma-Greens upon waking and wait 20-minutes before eating or drinking anything. Occasional I mix it in herbal tea in the evening as well. I also cycle off after 150-days for 2-3 weeks. I’ve been able to produce more power on the bike without lactic acid, so bring on that tingling! I
