But does the study actually state whether the administration was in fact divided, like you are implying? If it doesn’t, then we have to assume the daily administration was a single concentrated dose of 6.4g.
It's divided doses. 800mg every 1.5hr 8x.
Thirty healthy, strength-trained individuals were randomly assigned to the experimental groups placebo (PLA) or BA. Over 5 weeks of strength training, subjects in BA took 6.4 g/day of BA as 8 × 800 mg doses each at least 1.5 h apart.
"β-Alanine supplementation was effective at increasing power output when lifting loads equivalent to the individual’s maximal strength or when working at maximum power output. The improvement observed at 1RM was explained by a greater load lifted, or strength gain, in response to training in the participants who took this supplement."
eh, pass. I'd rather have it as an ergogenic and daily dose it around a gram for cumulative benefits than try and take 800mg 8x a day with a specific window.
