I found regular Beta alanine was just too much of a hassle with having to practically take it throughout the day and the tingling got to be a bit much. But the main thing was that my performance increase was marginal.
All that changed when I started using Beta-7. The tablets are easy to carry with you and take with meals. My skin no longer felt like I had ants crawling all over me. Plus, for whatever reason, I noted a better was effect in the gym.
At least for me, Beta-7 makes a big difference.
