With perhaps creatine, beta alanine has a ton of science to back it up. Think of it this way, it will help buffer lactic acid in my oppionion better then creatine. What this means if you were about to finish a set at say rep 5 you might now get 6-8. Big difference.
Word of warning you will get a tingling sensation in the early days that you use it in your skin. Almost like wearing a wool sweater without a shirt. It will go away. Beta alanine is mighty good stuff.
The answer really depends on how you train. For a PL 1RM ME inclined sessions I dont think it does hardly anything. If you are more higher rep inclined than there can be an appreciable gain in reps
I've used it and not used it doing 4 hour cardio sessions when I was a long distance runner. I noticed a substantial reduction in muscle fatigue during sessions I used the beta alanine. It made training for longer periods far easier.
With weight training, I notice it most during high rep raise sets (anterior, lateral, and rear). It allows for more reps with a noticeable reduction of *burn*
thats weird that you mention laterals because thats one exercise that exploded in my capability to do higher reps. I could do like 12 reps at a certain weight with beta alanine I could pound out like 20 reps. It brings back the weird tingly sensation and chemical taste in my mouth thinking about it.
I use it , pre and post workout. I notice a big difference when I forget to take it before my workouts. I am able to handle alot more workloads with it.
I take 5 caps pre and post and use TrueProteins stuff, I've never experienced the tingles from it.
I love it def saw more reps during workouts... I also like the crazy tingle all over my body. a nice responce that lets me know it is flowin through my blood stream
One of the few supplements I do notice if I drop or not... good stuff to me but it won't blow you away.
When I'm on my game I take 2 of TP's caps every few hours on training days leading up to the session and possibly a double dosage 30-45 minutes prior if I haven't taken in a several dosages prior for a total of 6 during the day. Off days are generally 4 caps.
I do get the tingles especially on my ears and back, like I cut my hair and some of the clippings found their way under my shirt haha.
