Optimum Nutrition Instantized BCAA, Unflavored

Anabolic & Anti-Catabolic Muscle Support

Used before endurance training, the Branched Chain Amino Acids (BCAAs) leucine, isoleucine and valine can help spare muscle. Used after strength training, they help kick-start protein synthesis which plays an important role in muscle building. ON’s BCAA 5000 Powder delivers five grams of BCAAs per serving in the preferred 2:1:1 ratio of leuncine to isoleucine and valine. It’s instantized for easy mixing into water, juice or post-workout shakes.

Beyond The Basics

5 grams of BCAAs per serving with a 2:1:1 ratio of leucine to isoleucine and valine. Available flavored and unflavored for stacking and stimulant-free, so you can use it anytime.

Unflavored review

A stage 2 lifting product

At this stage I use three products
1) Pure Whey ( I prefer Optimum whey chocolate )
2) Creatine (No preference)
3) Optimum Nutrition BCAA 5000mg unflavored.

Why Optimum -

Straightforward, no flashy packaging or complex list of ingredients promising instant gains. I was drawn to BCAA suppliment solely on my past experience with the Optimum brand. Their products mix well and do the job.

Why BCAA -

I train 4 days on 1 day off. I push myself hard and as a result i'm drained afterwards. I say that this is a stage 2 product because it will take you some time to truly drain yourself. If you're just starting out at the gym I recommend that you stick to just Whey protein. Why? Because you have a lot to learn about yourself and your form before you tire your targeted muscles out enough to warrant this product.

"I know i'm ready for this product stop trying to sway my decision and review the product itself"-

I don't draw out the bitter and sickening taste of this product, nor do I complain about it. Amino acids aren't going to taste great, accept that. If you can take a shot of tequila you can suck down a few shots of water with a serving of this. I tend to put about 3 ounces of water in a cup with a serving of BCAA powder swirl fast and shoot it down. Refill the glass with another 3 ounces and get out any residual product. If you're taking Creatine replace the water with some juice to get your sugar spike.

When to take - One serving before a workout and one after (I do about .75 serving per)

Results - Immediate notice in decreased muscle fatigue. I had some terrible DOMS with most muscle groups.

A friend at my gym told me about this stuff. . She was about a hundred pounds overweight when she started at the gym and now she's the most cut, incredible athlete there so I tend to listen to what she says. She recommended the unflavored, to avoid food coloring and unnecessary sugar

Things that happen to me half an hour after taking this:
-I have a massive amount of energy and can do a lot more in my workouts without fatigue.
-My face no longer turns beet red during hard workouts.

How I deal with the taste of the unflavored powder:
-I can stomach this with just water, but it's slightly bitter and I cringe a little afterward.
-I cannot stand it mixed with milk or creamy chocolatey stuff and absolutely cannot drink it like this. *Pour down the drain.
-I prefer it mixed with lemon juice, honey and water or with green machine and lemon juice ....the lemon juice seems to be the key.

*note: if you mix it with Green Machine, do not leave it on the counter. The appearance can be traumatic for other family members.

Was looking for a plain old container of BCAAs with 5000mg servings and a 2:1:1 ratio for leucine : isoleucine : valine and that's exactly what this is. Flavorless BCAAs that mix well into anything, I just add it into my regular pre-workout and head to the gym. It doesn't clump, it doesn't change the flavor, it doesn't have any texture.

It does exactly what it's supposed to and I'll be buying more as soon as I run out.

The powder mixes just fine in a shaker bottle, which most users of the product would be using. On flavor, you must understand that BCAAs are inherently bitter. You cannot fault ON for providing the product as described. Honestly, taking it straight isn't that bad, however, I understand that some people are highly sensitive to bitterness. If flavor is still a problem, my recommendation to treat it like bad tequila. Countering the bad taste of hard alcohol works just as well for unflavored BCAAs. Mix less than 8 ounces of water with the powder. The less volume the better, so you'll be able to gulp it down in one go. Take a small amount of salt on your tongue, gulp down the liquid, and chase with some straight lime or lemon juice. Salty is a well known counter to bitter. Prepping the tongue with pure salt helps soften the bitter shock. After gulping the BCAAs, the bitterness is well again countered with an alternative strong taste, sour. Using lemon or lime has the additional benefit of ending on a refreshing citrus note. This combination completely clears any of the rubbery bitter aftertaste. For those who want to avoid artificial flavoring or sweeteners, and prefer coming up with their own recipe, I recommend this product.

This stuff tastes like a bunch of amino acids. And, it works great! I take half pre-workout, half peri-workout, and another half post workout. In addition to micronized creatine supplements, my fatigure and recovery are great. Good brand, good product, good price. I'm about to buy some more.

I just finished reading the bad reviews based upon taste. lol. I'll take mine straight in water, or mix it in my peri or post workout shakes.

Anyone who works out seriously is already eating when they aren't hungry. The romance of food is gone. The job is to get in you what you need, when you need it.
