Expert Opinion and Usage

For optimal results with either supplement, consider a few points. Always assess your caffeine tolerance by starting with a half-serving. As Cellucor advises, always check with a licensed medical professional before beginning any new supplement regimen. The tingling sensation from Beta-Alanine is harmless and expected. Consistent use of Beta-Alanine builds up in the body and shows benefits over time, so cumulative use is key for endurance. The ingredients in these products are well-studied and have a track record of supporting workout performance when used correctly.
