"Excellent preworkout just what needed to use prebedtime workout"
"Bes5 stim-free pre!"
"Best stim free pre workout on the market"
"Taste great as always. I gave it a four because I wish they had a stim free that had the higher amounts of pre workout ingredients like Pre Jym PLUS."
"I took "Stim-Free Pre JYM Pre-Workout" for the first time last week and I was impressed. Since I'm sensitive to caffeine, I had to give Dr Jym's stim-free pre-workout a try. It works and it packs a punch! Follow the directions: "Initially use 1/2 serving or less to assess tolerance. " Looking forward to more flavors."
"Great taste. Best of all it's caffeine free for late night workouts. All the quality nutrients you need as well."
"I wish it came in a new flavor! Like the raspberry lemonade!"
"Best stim-free on the market by far. Other companies offer different types of stim free products but never put the proper ingredients in them or their under dosed. This is my go to because I’m sensitive to caffeine now. Great product. I’d love to see a stim free pre jym plus."
"Second container so far and it's good stuff. I take on an empty stomach for the most part, 30-45 mins before my workout. Great pumps. I add a little bit of creatine to get my 5 ish grams. I didn't realize it already had betaine anhydrous which is great. I also prefer no stim so I can tailor how much caffeine I actually want (from another source) depending on what workout I plan to do, but still get the rest of the ingredients from this. No issues with sleep."
"Out of the different brands of pre-workouts I’ve tried, this is the one that I have stuck with. I can feel it fuel my body for lifts and cardio cool down. I’m trying the StimFree version since I work nights and workout in the mornings. I’m still able to get to sleep at a reasonable time with ease and wake up feeling refreshed."
