Wanna start with flavor (Rainbow candy) it's just amazing. Best high stim pre flavor. No bad aftertaste. Pre itself is very good, euphoric, buzzing, focused, good mood elevation, great kind muscle connection, surprisingly good strength output. Feels also healthy as well, doesn't burn out your adrenal glands. Getting all the benefits with potent ingredients with lesser dose. 2 round scoops provides awesome workout session. No side effects, smooth in best way possible.
