Customer Reviews
Consistently reliable caffeine
I've been buying the gallon liquid caffeine refill for over a year now, and this latest order was just as good as the first. I always get it for my morning coffee, and it never changes the flavor, which is key for me. Shipping always takes about a week, which I've come to expect, and it arrived securely packaged as usual. I keep coming back because I know exactly what I'm getting, and it's a much more economical way to get my caffeine than buying individual energy drinks. They've been very consistent with their product and delivery times.
Worked as advertised
Got the travel size liquid caffeine. Used it for a long drive. Easy to add, no taste. Kept me awake. Quick shipping.
Pretty good for workouts
So I grabbed some of that pre-workout caffeine liquid stuff, cause my gym buddy told me about it. I just squirted a bit into my water bottle before hitting the weights. Honestly, it worked pretty well! No weird taste or anything, just felt a bit more energized, you know? It got here in like, four days, which was cool. I mean, it's not like a magic potion or anything, but it definitely helped me push through my workout. I'd probably get it again.

i heard there's a discount for military folks, anyone know if that's still a thing and how to get it?
how does this compare to those Mio energy drops? are they similar?
Just wondering about shipping times to, like, California. Need it for a trip coming up next week.
can i stack the first order discount with the bulk purchase one? wanna get a gallon but also save extra.
hey, anyone know if this stuff actually changes the taste of your coffee? i'm sensitive to weird aftertastes.
