Make your muscle fuller, harder, leaner, and stronger with this rare supplement technology!

This one-of-a-kind formula is a valuable aid for building and preserving muscle. Bodybuilders, powerlifters, weekend warriors, collegiate athletes, and everyday fitness enthusiasts of all ages report gaining muscle and getting leaner when using Mass Amino Acids tablets as directed.

  • Muscle Building and Preservation
  • Recovery

Why people like it
  • The results: Clients report greater muscle fullness and strength in just 2 weeks. Men and women regularly tell us that Mass Amino Acids is the best solution they've found for protecting hard-earned muscle gains during a fat-loss or cutting diet.
  • Double your anabolic power: The chief ingredient in Mass Amino Acids is a partial hydrolysate of casein which contains large amounts of peptide-bonded amino acids (PBAAs). Studies suggest that PBAAs have up to twice the anabolic potency of regular food.

Who is this product ideal for?
Anyone who is struggling to:
  • gain muscle mass and strength,
  • maintain muscle mass and strength while dieting, or
  • rebuild muscle mass and strength after a temporary layoff from training.

Secrets to Success
  • Take 1 tablet for every 10 lb of body weight, daily. Divide your daily allotment of tablets into smaller doses. The best times to take a dose are with meals and during workouts.
  • Clients typically find that they get the most impressive results by stacking Mass Amino Acids with Ultra 40. A personal trainer told us that he puts his clients on Mass Amino Acids, Ultra 40, and a Beverly protein powder. Everyone who takes this stack reports getting leaner and stronger within just 2 weeks.

Amino Acids

I think this may be one of the best results I have had in a while. At 61 years old I think I am getting some gains happening. Only been on them 2 weeks but less muscle fatigue and noticeable strength.

An excellent source of aminos broken down into smaller peptides. I take these with Ultra 40 liver tablets with each meal.

My favorite supplement

I take 4 with every meal. I take extra if I eat sweets and my blood sugar stays more level. Should be a staple in everyone's arsenal

Good quality muscle tablets

these tablets are the real deal. usually need 1 tablet per 10 lbs or body. Hence, I would need to take 15 per day. But I only take 6 or 8 and can see and feel the effects in a couple of weeks already.
