  • 10 Atomic Lemon Drop

Flavor is solid. Very lemon-y which is good. I would definitely start with 1 scoop to access your tolerance. I've been using pre forever and my caffeine tolerance is extremely high, but when I used the full serving( 2 scoops), I threw up about 10 minutes later. But using it a few times after that it has been good. IMO, if they left the caffeine out, this would of been a fantastic Pump only product without the stims. Solid nonetheless

Was hoping this would be like a watermelon jolly rancher but wasn’t even close. Too much of a sweet taste just not the same, I won’t be using this one again.

Usually I add more beta alanine and citrulline to my pre, but wanted to give this a fair shake. About 30 minutes after taking it, the switch was flipped. Excellent focus, pump, and endurance - choosing to give this a go on an upper pull was a 10/10 decision too. Very happy with this purchase.
