High energy and focus
I’ve been using this product for years. I’ve tried other products and keep finding myself coming back to this. The flavor is great and love that it is stim- free. I’ve noticed I am very focused and have lots of energy during my workouts. It mixes well with water and is easy to drink.

Tastes great, good pump
This is my favorite preworkout because it is stimulant free, gives a good pump, and tastes great.

Scoops vs Servings
Solid product. Here is what I do not get. Its only 18 servings with less ingredients than Profilic1 (25 servings) at a similar price point...Please offer this product with properly dosed scoops like Proflic1 so we are not ordering this every 18 days. Charge more if you have to do and stop the 36 scoops gimick wording and set yourself apart. Its 18 servings.

Indifferent these days
Back in 2015 I COULDN'T GET ENOUGH of this product. I took a break from bodybuilding and came back a year ago, and repurchased this not long after that. I must say, I've probably used it 5 times and gave it to my brother. The flavor makes me nauseous these days unfortunately, and if I drink prior to training I wind up feeling sick with the aftertaste most of the workout. Doesn't work for me anymore, but I think my brother's been enjoying it. So if you like a pump product without caffeine it can't hurt to try. Cotton candy flavor used to be pretty good, too. But this flavor seemed like I wouldnt get sick of it so easily. Boy was I wrong :(

Great boost
I’m really enjoying this product. I was really nervous to try this because couldn’t take regular pre because I don’t consume caffeine normally so when I do, it keeps me up at night, even if I take it at 8 AM, but if I take this at 5 PM, I’m still able to sleep at 9. I also feel much more energy and can definitely push more weight with this. Will definitely be buying again!
