We all love caffeine, well most of us do anyway, and it’s got to the point where almost every pre-workout supplement out there is made up of mostly caffeine in ever-increasing amounts. We’ve talked about a lot of these in our article on the best 10 pre-workout supplements. But not everyone can consume caffeine, finding a pre-workout supplement that is stimulant free is the only option for them.
Also, even you – caffeine lovers – should contemplate a stim-free pre-workout every once in a while. While caffeine is amazing, you can fast build a tolerance meaning that all of the benefits that you enjoyed (increased power, increased energy, less fatigue, and lowered rate of perceived effort) can vanish!
You can also begin to experience some negative side-effects such as increased cortisol, troubled sleep, and even weight gain. If you are beginning to suffer the effects of too much caffeine, then a stimulant free pre-workout (combined with a caffeine-free diet) can help to lower your tolerance levels while also providing you the energy required to smash your workout. In this article, we are going to look at 10 of the best stimulant free pre-workouts available to you.

In such a competitive market, you would expect to find a serious contention for the no.1 spot on this list. Well, not really. Transparent Labs STIM-FREE stands alone at the top of the list here, with no real close contenders at this point.
The easiest way to explain this is that different than a lot of the runner ups on this list, Transparent Labs actually designed STIM FREE to be a standalone fully functional Pre-Workout, rather than an add-on to their stimulant Pre Workout. With this approach, it is not surprising that STIM-FREE carries exactly the same label as the brand’s to PRE-SERIES BULK minus the stimulants (caffeine & l-theanine). This means that you are getting full impact in all of the departments. This product will increase strength and endurance (6g Citrulline Malate and 3g Creatine HCI), lower fatigue (BCAAs, 4g (!) Beta-Alanine, Betaine, Taurine), and improve focus (L-Tyrosine, Choline). All of the ingredients are either fully or over dosed, and there are no fillers here!
The bottom line, Transparent Labs PreSeries STIM-FREE is so good that you would be challenged to notice that you are actually using a caffeine free pre-workout!
Big Noise from RedCon1 is a very impressive looking pre-workout with a beautiful design. You get a choice of three flavors (Blue Lemonade, Watermelon, and Strawberry Kiwi) and each pack contains 30 servings. REDCON1 Big Noise contains a lot of the same ingredients as the no.2 on this list – Hype Extreme (Huperzine A, Rhodiola Rosea, Alpha GPC) while also containing BetaPower (Betaine) which is supposed to increase strength and muscular endurance, Astragalus Membranaceus which is an anti-inflammatory, and Agmatine to bring even more pump into the picture. All in all Big Noise is a very well rounded Pre Workout with a lot going for it as far as power, endurance, pump and mental focus.
NutraBio’s PRE STIM FREE not only carries a very similar name to our no.1 spot holder but also has a lot to be proud of! lets take a look at the label.

As a result, we can say that this is a fantastic pre-workout supplement that will increase energy, lower fatigue, increase the pump, and help you to focus throughout your session.
