      What is beta-alanine?

      Beta-alanine is the modified version of the amino acid alanine. The body converts beta-alanine into carnosine, which supports exercise performance and endurance.

      Directions

      Do not exceed recommended daily intake. Use only as directed. Taking one-half [1/2] scoop mixed with 8-10 ounces of water, 20-30 minutes before training to determine tolerance. If increased intensity is desired, take one [1] level scoop mixed with 10-12 ounces of water 20-30 minutes before training. DO not exceed 2 scoops per day. Important: During your workout, it is recommended that you drink plenty of water to stay hydrated. Some individuals may experience a harmless tingling sensation, which is caused by Beta-Alanine.

      Warning

      Not intended for persons under the age of 18. Keep out of reach of children. Do not use if pregnant or nursing. Consult a healthcare professional prior to consumption if you are unaware of your current health condition, have any pre-existing medical conditions, or are taking any prescription medication. Reduce or discontinue use if sleeplessness, tremors, dizziness, nervousness, headaches, or heart palpitations occur. The product contains the naturally occurring amino acid, Beta-Alanine, which causes a harmless tingling sensation in some individuals. This effect should diminish after a couple hours and should ultimately subside after multiple days of continued use. Improper use of this product will not improve results and is potentially hazardous to a person's health. Store in a cool, dry place.

      Like it
      The taste impressed me the most. I chose the Blue Raspberry flavor - absolutely perfect! Until now, I hadn't found a product that doesn't feel heavy on my stomach while I'm training. As for the stimulant-free version, I don't really notice any effects yet, but we'll see how it performs after using it for a bit longer. ??

      Perfect for a stim free, caffeine free preworkout.
      I don't do caffeine and have always steered clear of pre workout. I got recommended a stim free pre work and researched my options. I chose transparent labs since they offered a cleaner caffeine free stimulant free option. The sour flavor is perfect for me and I love using it so far. No itching or weird sensations and no crash. I feel good during my workouts and I can go about my day and fall asleep at night without a problem. I do only use it early in the AM so I can't speak about any night effects if used late in the day. I only do a half dose since that is what works for me.
