For a long time pre-workouts have been getting stronger in terms of stimulants. So many products now are absolutely loaded with stims, be it caffeine in one or more forms, theacrine (TeaCrine), the slowly disappearing 1-3 DMAA, or one of so many others. While there are some non-stim pre-workouts on the market, many of them don't have quite the same great profile as their stimulant counterparts.
Nutrex's Outlift Stim-Free packs the same punch in terms of pump as their standard outlift just without the caffeine! There is still a great pump combination, stemming from the 8 gram dose of Citrulline Malate and 3.2 grams of Beta-Alanine. They kept the 6 grams of BCAA's, but they added an additional 2.5 grams of Betaine Anhydrous. This combination of BCAA's and Betaine enhances both recovery and endurance significantly.
Stim-Free Outlift still contains 2 grams of Taurine for a boost in terms of mental focus to keep your mind sharp during the tough workouts.
My personal favorite thing about this product is that it's still an awesome preworkout, just without the caffeine. It gives me the freedom to go without stimulants when I don't feel like I need them, but is also perfectly okay to combo with most other pre-workouts. It's a bit pricey in a stack, but a half scoop of this is still dosed heavier than most nitric oxide boosting, caffeine free pre-workouts. I never recommend certain combinations unless you've used pre-workouts for awhile and are fully aware of your tolerances because certain ingredients can react together and the combination may be stronger than expected, but stacking this with an energy centered preworkout yields great results for me.
