Ive been lifting serious now for 4 years and never tried beta alanine so i thought id give it a shot. Ive been taking Nutraplanet brand BA @9grams/day total divided into 3 servings for 3 weeks now and I literally cannot get sore anymore. Ive also found my recovery between sets has dramatically gone up as well. Also the tingling sensation was greatly reduced after the first week taking it, but I take it with food the majority of the time to slow absorbtion so that it doesnt kill me. I know this isnt placebo because I got it assuming it would be a fail like creatine was for me(get nothing from it) and for the most part I dont respond to any non-hormonal supplements. So for anyone that hasnt tried it yet i would highly recommend giving it a test run because its reasonably priced as well, $20 for 2 months worth (500g). I hear it takes a while to build up in the body as well and should get continually better for like 2 months or whatever, so im excited to see how strong this stuff is long term.
