Product Overview

BCAA 5000

Key Benefits for BCAAs*:

  • Help stimulate Protein Synthesis*
  • Decrease Protein Breakdown*
  • Can serve as alternative energy source*
  • Essential Amino Acids that must be obtained through diet or supplementation*
  • Complements the effects of other core supplements such as protein and creatine*

If you’re stuck in a rut with your diet and supplement regimen, then maybe it’s time to branch out to Branched-Chain Amino Acids (BCAAs). While these amino acids are not new to the supplement scene, new research continues to suggest that they can have a significant impact on your training. Composed of Leucine, Isoleucine and Valine – these aminos form the perfect trifecta for helping you reach your bodybuilding and athletic goals.*

Of the 20 amino acids that our body’s use for muscle and other important tissues, BCAAs may be the most important of all. As indicated by their name, they have a unique configuration that results in a branched structure not seen in other aminos. Also, unlike other amino acids, they are primarily broken down in muscle as opposed to the liver. The ability of muscles to directly breakdown BCAAs means they can serve as an alternative source of muscle fuel, especially during extended exercise when carbohydrate stores may start to dwindle.*

Probably the most exciting feature about BCAAs for bodybuilders and athletes is their ability to support protein synthesis.* The BCAAs, and especially Leucine, are able to directly activate key enzymes that are involved in building protein.* As if that weren’t good enough, supplementing with BCAAs may help to decrease protein breakdown as well.*

So just how much BCAAs are needed in order to harness all of their benefits? It really all depends on how much you weigh and your individual workout routine. It is often recommended to take between 85 to 100 mg per kilogram of bodyweight. For those of you not to familiar with the metric system (it never did really take off in the U.S.) this translates to about 6.5 – 7.5 grams per day for a 170 lb. individual, or 7.6 – 9 grams in a 200 lb. individual. You can take your daily dose pre-workout, and follow that up with your recovery protein shake immediately after exercise.

Taste-wise - absolutely delicious Product quality - excellent. Definitely helps in recovery. The only reason that I don't rate it at highest grade is because it's mix-ability. It tends to produce a lot of foam no matter how long you shake it. This foam holds a lot of powder actually and you have to eat it with a spoon of just throw away.

I decided to give this a try when it was on sale, ordered a blue razz and a watermelon. Typically, I hate watermelon flavored drinks but for some reason this one tastes awesome and I ordered it again! As far as how well it works, who knows how well any of this stuff works. I drink it while I work out and I like it better than water. It's fairly inexpensive so I'll keep using it.

So far this is one of the best BCAA sups I've used...sometimes it creates a froth after it's shaken, but after shaking a bit more, or leaving it for a second it disappears. I stack the blue raspberry with my blue raz flavored Evultion Nutrition ENGN pre-workout, works and tastes great! I also use solo during and/or after my workouts and have noticed an improved recovery time.

Second type of BCAA's I've used first being on Nutrition (unflavored). The stuff taste like crappy but what do you expect when you drinking something that's unflavored. It doesn't blend nearly as well as the on stuff but apparently that's normal for most BCAA's, "They don't mix they melt" studies say. That being said if you throw them into your blender or what ever before getting ready for the gym you'll be fine. Now for the results, I can say that I notice a better recovery time with this product vs. That pretty much it. Ps. I bought unflavored so I can mix it with other drink options.

The taste of the Watermelon is incredible. It's just like a watermelon jolly rancher!! Gives me enough oomph to push through my workouts while cutting, and definitely has helped with recovery. I'd recommend this for sure!

Great watermelon taste. Disolve quickly, great endurance during my workout (i use it as intra) You cant get better for the price, i will stick to met-rx bca5000 ! I was using alpha amino then aminox but met rx is better and you know exactly what is inside, no propriety blend! I love it , stack with one scoop of met rx nuclear x, awsome!!!

Pretty solid for BCAA. Gives you 5 grams of good BCAA for intra or post, helps with protein synthesis. This one does the job nicely, as it mixes nicely, without clumps maybe a few of the things floating, but it dissolves in no time. Taste wise I must say, I was impressed. Didn't know what to expect but the Watermelon tastes like a jolly rancher candy. Personally I love this product even over the Xtend, with respect to product and taste. Gives you what you need and the price is right. Met-RX impresses with this one. Thumbs up!!

Taste was good, has a good amount of bcaas per serving. The added Vitamin B helps as well. The price is reasonable and it doesn't have all those added ingredients like Beta Alanine, Arginine, Glutamine, etc that you don't need. Quality product and I definitely recommend it.

Great product. Mixes very easy with water and taste great. I was very surprised at how well this mixed and taste. As far as overall results, I have only been taking this for about a week now. I still strongly recommend this product.

Does not mix easily in water. Some BCAA powders it heps to let them 'soak' a little, but this stuff is like powered chalk, it just sits there, clumps up and sits there. Taste is not great either, very bitter for a flavored BCAA. If it were one or the other, I could live with it, but these days, there's no reason to put up with both.
