TAG is the perfect choice for any individual that wants a top-quality product that delivers uncompromising results. TAG will promote increased recovery, promote muscle growth, and improve general health and well being...guaranteed! Metabolic Nutrition is committed to producing only the highest quality nutritional supplements, with the backing of sound research and designed by a medical doctor. Metabolic Nutrition was in fact the first company to bring Trans-Alanyl-Glutamine Di-peptide to the supplement market. TAG has been praised by athletes, doctors and consumers, T.A.G. is the only "Muscle Targeted Glutamine" product currently available. Thanks to its exclusive "di-peptide" designed chemical structure, T.A.G. Is able to be mixed in water or other liquids with no degradation which can with other, inferior glutamine products.

Free-form L-Glutamine is largely used in the intestines which leave only around 10% available for use by the muscles, T.A.G. is a superior form of Glutamine because it's 100% absorbed into the bloodstream and delivered right to the muscles. Designed to improve muscle recovery and repair T.A.G. stops the loss of muscle glutamine while training,

effectively blocking "protein catabolism" (i.e. muscle breakdown)...therefore supporting maintenance and muscle growth both intra and post-workout. Besides promoting increased recovery during and post-training, T.A.G.provides a total solution to recovery by increasing protein synthesis, promoting the release of GH, supporting the ideal functioning of the immune system, and stopping muscle catabolism, which makes it a key supplement in any athlete's program.

Achieve your goals...

  • Promote new muscle growth quickly with no changes to your training or diet!
  • Power through training plateaus - boost your strength in as little as 1 hour!
  • Done training? - your muscles will stay pumped all day long!
  • See changes in your physique in the first week!!!

Glutamine – a popular supplement used to help build muscle...

Yet they don't realize is that most of the currently available glutamine will never reach their muscle tissue. "What's that?" you can hear them say..., "Isn't Glutamine used for helping recovery and repair of muscle fiber, enhancing the immune system, stabilizing blood sugar levels, and increasing anabolic hormone response!?!?" Well, the answer is both yes and no...the fact is it's been proven in as well as outside the lab, that as much as 90% of "regular" L-Glutamine is utilized only by your intestines to enhance intestinal health, and benefit the immune system – BUT THAT DOES NOT INCLUDE BUILDING MUSCLE! That leaves only 10% that will make it into the bloodstream and be available for the repair and building of muscle... if it actually gets that far. You see, your body is actually a very interesting machine... its single purpose is to enhance how well it functions...sadly, building new muscle is a low priority...BUT it's your only priority! You've probably used "regular" L-Glutamine for some time now...but when's the last time you heard comments from your friends, or people at the gym telling you how great you look and commenting on your new muscle?...probably been a while! The reason is you and many others are cramming 10, 20 or maybe 40 grams of "regular" L-Glutamine before, during, and after training..trying to build more muscle...just to end up with the same muscle you have now... but your colon must be really healthy!

Bigger Muscles Or…

a healthy colon? Researchers that analyze the anabolic (synthesis of living tissues) and catabolic (destruction of living tissues) body processes understand the strength of Glutamine. However, their research is targeted only on how the whole body functions...not on building muscle. It's true "regular" L-Glutamine has its benefits, it has its drawbacks for those interested in recovering and building more muscle. To put it simply, "regular" L-Glutamine does work...but can we make it work better?

This seems like a simple question but there are a few things we need to know, such as, what are the shortcomings of "regular" L-Glutamine? Newer research studies have verified "regular" L-Glutamine's major drawbacks regarding its capability to be delivered to the muscles and be usable: First: L-Glutamine is unstable and rapidly degrades in seconds of being blended in water or other liquids making assimilation by the muscles near impossible. Second – as much as 90% of "regular" L-Glutamine is quickly absorbed to be used by the GI tract only, which leaves just 10% for the muscles. Third - remaining "regular" L-Glutamine is quickly used within one hour, there are no extended benefits afterward, and finally Fourth - remaining (L-Glutamine) provides little to the muscle amino pool resulting in little benefit for promoting new muscle growth and activating the critical "Anabolic" hormones of the body. Most "regular" L-Glutamine users have realized that it doesn't seem to matter which brand you use or how much you take, it's not making a big difference...however, now you understand why! Every scoop you take never really reaches the muscles (... your intestines, yes) what's the answer?

Introducing the Muscle-Glutamine!…

Introducing T.A.G., ( known as trans-Alanyl-Glutamine), the first 4- step muscle-building Glutamine! T.A.G. works by solving the four problems that stop "regular" L-Glutamine from fulfilling its potential and giving you the ability to build as much muscle as can handle!!!

Here's how T.A.G. works:

  • STEP #1 Giving you a completely stable dipeptide chemical structure that's potent enough to be able to be mixed in water or other liquids with no degradation, so your body can absorb it ...
  • STEP #2 Allows complete assimilation (digestion is not required) into the bloodstream with no need to be digested in the stomach or GI track – this means that100% is available for use by your muscles, filling them with the fuel necessary to recover and grow new muscle...
  • STEP #3 Thanks to T.A.G.'s exclusive bio-available structure, it can circulate through the body as a time-release compound until every last gram is delivered to the muscles (typical time release is 14 hours!)...
  • STEP #4 T.A.G.'s exclusive dipeptide chemical structure provides 98.9% (compare this to "regular" L-Glutamine's 60%) of the important amino acid pool required by the muscles to recover and grow, this means bigger muscles that look pumped and hard as a rock!

But there's more, because of the direct assimilation of T.A.G., it has an additional effect on regulating Insulin response to even levels during the day which activates a positive anabolic environment as well as a positive nitrogen balance to allow your body to build new muscle. T.A.G. Provides your body with the tools it needs to build you can focus on working out without worrying about over-training - so every time you're at the gym you're building more and more muscle, so much that, like the Incredible Hulk, you'll be exploding out of your clothes!


It's SIMPLE.. just scoop, stir, and swallow...

It's as easy as that... in fact it's so easy you'll question why it hasn't been thought of before now. You'll be stunned, can building Monster Mr. Olympia arms, a Strongman back and Powerful Powerlifter legs be as easy as consuming 1 to 3 scoops (depending on goals) a day mixed in water...or, add it to your protein shakes...the mildly sweet flavor goes well with any liquid you choose! It's really that SIMPLE!!! The great thing is that T.A.G. only takes about 2 seconds to mix, so there's no prep-time at all, just add it into your daily program!

BUT BE WARNED!!! -T.A.G. is strong enough to begin working on the very first day you use it! Your strength is going to shoot up...your endurance will dramatically increase...your energy will never there's no need to work out for hours and hours thinking it will build more muscle - it is, after all,

T.A.G. that helps to build muscle...and as we should all know, you only build muscle when you are done at the gym, by allowing T.A.G. to feed your starving muscles! It'll begin with you realizing that exercises which used to be hard - are now much easier!...then, you'll notice that your biggest clothes will feel a little tight!!...then finally the biggest guy you know will walk over and ask if, " need a spot?" once he's seen the big weights you're tossing around!!!

Once you start using T.A.G., you'll ask yourself why you've been wasting your hard-earned cash on "regular" L-Glutamine...and now you'll be recovering faster and putting on new muscle more rapidly because of T.A.G.! The world's only engineered-dipeptide-Glutamine, created and manufactured for the single purpose of building muscle faster than ever.

Now's the time...Order Today! ...order T.A.G., the first and "only" 100% absorbable muscle-building Glutamine!
