Product Overview

During exercise, and especially high-intensity training, glucose and glycogen are broken down for energy. In the process, hydrogen ions (H+) are also produced within the muscles. H+ accumulation causes the muscles to become more acidic and ultimately leads to fatigue. Packed with Beta-Alanine, Histidine, and Phosphates, our Threshold formula is designed to help boost your intramuscular buffering system so that you can train harder, longer.*

Beyond The Basics

  • 1.6 grams of Beta Alanine
  • 550 mg of L-Histidine
  • 4 Mineral Electrolytes
  • Supports Carnosine Synthesis*

I use this in my pre-workout stack, it helps me through long workouts, I also add to my post-workout O.N. protein shake, seems to help with exhausted muscles. Mixes well and has no taste, perfect..

I chose a 7 because the Taste isn’t very good but you don’t really notice a lot of difference if you take it with a strong pre workout. It does give me that tingling feeling that a lot of people love. I love it myself so it does do the trick. I would suggest 5g a day and dry scoop it. Just put the powder in your mouth and take a sip of your favorite beverage. Swish it around and then swallow it. That way it’s effective immediately and the gross taste is quick.

This beta-alanine product from ON works great! I'm use to beta-alanine from pre-workouts, so I usually take 2-3 scoops of this stacked with ON's creatine and glutamine before I workout. This product does work great, and definitely gets me through a long/heavy lifting session. I will continue to buy this product and might try the unflavored so I can mix more into the stack.

To start this off I absolutely love Optimum Nutritions products. They have never done me wrong when it comes to bettering myself in the gym. Ok so what we are talking about it the ON Unflavored Beta Alanine Powder. This stuff is absolutely amazing in terms of energy and increased endurance when it comes to heavier lifting. The only set back I had with this was stomaching the stuff. No matter what I mixed it with it had a slightly odd texture that just doesn't go down easily. My tolerance is pretty high so I would use two scoops instead of the recommended one. You will get the pins and needles feelings (This feeling for me usually starts in my hands and ears then goes into my upper back), but I do enjoy the feeling. Definitely gave me a better pump due to being able to lift longer. I usually only use the beta alanine powder on days i'm working upper body because that win it works the best for ME. I would recommend however taking it a bit sooner than 30 minutes before your workout, maybe 15-20. Overall highly good product with a modest price especially ordering on here, but will be trying out the flavored version to see if it goes down any better.

This is exactly what I want beta-alanine as Carnosyn. Amazing price, simple and effective. The only drawback is slight bitter taste if you mix just with water but if you mix it with anything even mildly flavored it mixes perfectly and there is no unpleasant taste whatsoever (at least in my opinion). Again I will continue buying my Beta-Alanine from ON because the product is effective and the price is right.

This Beta-Alanine Powder is LEGIT! I love using it with my pre-workout. Overall the taste is great and I am a huge fan of the results I have been seeing. I have gained 10lbs over the past 6 months and not only does this give me energy it keeps me motivated to reach my goals when I hit the gym. I love this stuff!!!

Mix this with my pre workout! Yes it make you itch! But if you start with a small dose and move your way up you won't regret it! You can get crazy pumps and feel the difference in how long you can keep your pump going! Great for doing drop sets and super sets!
