Yes but that means its working! Beta-Alanine is a key component to muscular endurance and that is what makes your skin tingle or itch. Due to poorly formulated products on the market, people associate tingles as bad but it's actually other ingredients that make you feel sick. GOOD NEWS, MYB is easy on the stomach and is clinically formulated so you don't feel, sick, light headed, and will actually boost your workouts. We recommend starting with 1/2 a scoop to test sensitivity and even eating some carbs prior to exercise to reduce tingles.

MYB only uses 90 mg of natural green tea extract to prevent this! Research shows that caffeine dosages over 100 mg (up to 400mg) poses no benefits and actually diminishes performance, causes lightheadedness, & jitters. If you are sensitive to caffeine try our CAFFEINE FREE PRE-WORKOUT or start with 1/2 a scoop to assess sensitivity.
