In their own words
“I was noticing that I no longer needed Theanine or any other GABAergics to calm my anxiety.”
“Beta-alanine, in my experience makes me to where I can’t focus. I also have some to a guy before a calculus test. He said was so much more difficult to focus. Wouldn’t recommend as a nootropic.”
“It works mostly at boosting your ability to do reps in the range of 10, i.e hypertrophy work.”
“Need to take beta alanine and creatine daily to get the effect just fyi. Tingles are just a side effect and should pass after a couple weeks; I feel the caffeine and beta alanine (i get the tingles from b.a.)”
“while I love the energy I get from them, I can't stand the skin itchiness. It drives me absolutely nuts!”
“whenever I have any over that at one time, it makes me want to fuck anything in sight. Also, sex during the tingles feels about 5x better than normal.”
