Taste is ok, but the performance is there. I don’t have trouble sleeping after taking this pretty late at night but still get a little boost.*

This is one of my favorite non-stim options. Dosing is solid and it isn’t loaded with filer ingredients. Tastes good and gets the job done without breaking the bank.*

Mix a scoop of this with a 1/4 or 1/2 scoop of another pretty high stim pre, and it works great. I use it alone for later night workouts and it doesn’t keep me up but still helps me stay focused and power through my training.*

I received the unflavored version and it is horrendous. You very well taste whatever it is that you taste...as far as the product itself it really didn't do much for me...decent pump*

Great flavor, good price, and high doses of solid ingredients. I like that this is stimulant free, as I can mix with a half scoop of a caffeine-containing pre-workout to get a little kick without so much of the caffeine.*

Great pre-workout powder if you want the help with pump, mind/muscle supp, and endurance....without the caffeine. Since caffeine is catabolic, you don't have the thoughts of muscle wasting in the back of your mind if lifting in a fasted state.*

The taste is bitter, but what can you expect from the Unflavored. Any juice or pre stack will make it better. I feel a bit of a pump, but not as much as I was hoping.*

Got this because of the dosing. I used to get Allmax Impact Ignitor....but its been reformulated without the N.O. ingredients. I guess it was Allmax's way to get you to buy two items vs. one that had attributes of both. All about the buck. But if you want a stim free pre.....this is a great one.*

This product gives you a great pump. I went with this brand of pump because it contained lions mane. The unflavored has a very odd and peculiar taste, almost like rotten eggs. It’s drinkable, but even for the unflavored I would give it 0/5 for taste. For overall effects of the product and the pump I get when I consume this, 5/5. Effective product, not so great taste. Maybe the flavored ones taste better*
