Helpful and flavorful boost

Review by Sarah Mitchell on Sep 7, 2021
I have been enjoying the energy boost and love the flavor of the many flavors I have tried. I have found the green tea to be a good addition to my diet & not the niacin found in so many other energy drinks. I too would love to see a mix pack, a trial pack of sorts, to try new flavors. Maybe a 'make a mix' box or something.

Take it every morning

Review by John Kriskey on Sep 6, 2021
Been a Optimum Nutrition customer for over a couple of decades and have seen many products disappear and new ones added, I have been taking this every morning for the past several years and I can’t believe how much it’s helped me

Fruit punch

Review by Ashley Sullivan on Aug 9, 2021
Love this stuff my whole family loves it! We always get the grape and fruit punch which are our favorites sometimes I like to mix them together for a different flavor. I also have the blue raspberry which is amazing too. One thing I would recommend is a sample pack which each flavor cause I would like to try other flavors but don’t want to buy a huge jug and not like it:) I like to mix this before leaving work so when I get home I can workout cause it does help with not feeling blah during your workout! Gives good energy. And my husband is a huge diet Mountain Dew soda drinker and he has switched to this cause he likes it and I am so glad he has!

I love this stuff

Review by Cyn on Jul 11, 2021
My most pleasant surprise with this product is the flavor. So far I've tried grape, blue rasp, and orange and I've reordered both grape and orange. The flavors more mimic popsicles than medicine and are quite pleasant. The other thing I really like is that it dissolves quickly and 100%. There's no grit, no gross about it. I take sometimes as a pre-workout, others post, but no matter when it gives me boost I need and is just another ON product that I love.

Love this stuff!

Review by Party Jumps on Jun 9, 2021
After years of other products and too much coffee, I finally found this blend which has replaced coffee to become a morning staple for both my 4 day desk job and my 2 day field job. With such a low level of caffeine, there is no problem with over stimulation or crash and I find myself motivated, focused, and fueled to efficiently maneuver the tasks before me.
