A training friend turned me on to this in May. Tested in early july 2011. Use pre/post w/o and after excepting busy (physical) workday. 'Gauge servings / effort output. Replaced conc flavor with conc juice to keep all 'au natural. The Beta Alanine
, creatine & electrolytes deliver, period; I enhance with a couple pieces of fruit and cup of green/white tea. W/o's move along better (75m-2hrs) and recov comes within 15m of drinking surge (tiredness/stiffness drops to 5+%). In my opinion, ingredients of Surge are cleaner/better than Surge Recovery
. Cycle with it for more intense training program.
