The words ‘pre-workout’ and ‘caffeine’ practically go hand-in-hand. But if you work out late at night or are sensitive to stimulants, the last thing you need is a high-stim pre-workout—unless, of course, you dig the jitters or staring at the ceiling all night.
Skipping the caffeine doesn’t mean you’re stuck going into workouts with a shaker cup full of plain water. A stim-free pre-workout can give your muscles (and mind) the edge needed for you to rip through a killer workout. Check out the following six popular picks for the pumps, endurance, and determination you’re after—all without a milligram of caffeine.
1. GAT Sport Stim-Free PMP
Known for their no-joke sports nutrition supplements, GAT promises to pump up your workouts with Stim-Free PMP. PMP (which stands for Peak Muscle Performance) boasts a formula that supports mental focus, muscular energy, and serious pump. Star players include citrulline, beta-alanine, and agmatine sulfate—plus calming l-theanine to keep your drive smooth.
2. ProSupps L-Carnitine 1500
Our body uses the amino acid-like compound l-carnitine to turn fats into energy, so it comes in clutch when you want to make the most of your energy stores in the gym. ProSupps L-Carnitine 1500 packs an impressive 1,500 milligrams of l-carnitine. Use it to power lower-intensity, steady-state cardio, as part of your pre-workout stack, or to support weight management.
3. BodyTech Elite Nitrulline Powder
A fan favorite of BodyTech Elite’s line of advanced sports nutrition supplements, Nitrulline Powder contains a number of ingredients that support nitric oxide production, pumps, and endurance. (It also provides to a couple of workout-friendly vitamins and minerals.) A whopping 4,000 milligrams of citrulline (plus 1,000 milligrams of arginine and some glycerol) take your pumps to the next level, ensuring your muscles get the blood, oxygen, and nutrients they need to go hard.
4. Hilo Nitro Pump Gummies
If you prefer to chew your pre-workout rather than drink it, these Blood Orange Nitro Pump Gummies from Hilo make fueling up on the go a cinch.

BodyTech’s unflavored Beta-Alanine Powder mixes right into your water (or other pre-workout mix).
