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!
Primeval Labs has stormed into the top of the supplement world in the last 2 years introducing several best selling supplements. The company caught everyone by surprise introducing MEGA PRE as a stim free pre-workout. As one of the best stimulant free pre workout of 2019, MEGA PRE bring a complete pump & power package that you will feel. If you are into feeling swole and pumped, you really can’t go wrong with MEGA PRE by Primeval Labs.
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.
Performax Labs has a tradition of introducing high quality, fully dosed supplements and VASOMAX is no different. If when looking into a stim free pre workout, vascularity and pumps are a priority, Performax Labs VASOMAX answers the call. Historically the only downside to this product was flavor, but the last editions have improved dramatically this aspect which earned this Pump formula a spot on our top 10 list.
GAT PMP is one of the best pre-workouts out there with high levels of Caffeine and Theanine. GAT also sells a Stim-Free version that we will be looking at today. GAT split the ingredients into 5 parts. You have the usual Vitamin and Mineral section that contains Niacin as one of the main ingredients. Then there is the NO Enhancers (Beta Alanine, Arginine, Citrulline, Citrulline Malate, Norvaline), Pump Accelerators, PMP Focus & Cognition Modulators, and PMP Energetics.

HemaVol Powder by iForce Nutrition delivers a huge pump via its main ingredient Agmatine Sulphate (0.5g), this is responsible for a big release in Nitric Oxide. The pre-workout also contains Citrulline to reduce fatigue, L-Norvaline to inhibit Arginase and increase the amount of time that nitric oxide can be available. HemaVol claims to increase power and performance, and based on the ingredient list this seems perfectly likely.

The goal of Rich Piana’s pre-workout is to get you the biggest pump going during your workout.

It also contains Citrulline that can reduce fatigue while improving both anaerobic and aerobic performance.
Full as F*ck comes in four flavors: Blue Raspberry, Fruit Punch, Pomegranate, and Wild Berry with each pack containing 30 servings. If this was a ‘best pump’ product list, then the ‘full as f*ck’ would rank 1st. But in this list we are going after a complete non stim pre-workout ranking. But, if you are chasing a huge pump, then Full as F*ck is the pre-workout for you.
There are four main ingredients in Vasky by MTS Nutrition: Taurine (3g), HydroMax Glycerol (2g), Nitrogen (1.5g), and Vitamin C (100mg).

The last ingredient is HydroMax Glycerol which is a highly concentrated form of Glycerol that helps increase your pump. The supplement comes unflavoured and contains 30 servings per pack.
