You could use slingshot as an intra drink, or use it pre-workout on days where you don't want stimulants. This definitely comes in handy if you train at night.
more interested in 12 hour hour shifts in a very hot factory in summer months, it's nothing to weigh 10 pounds less after a 'night of fun'-lol. would use the smash fully loaded by itself for pre-workout. good idea though, billybob.
