Best Pre-Workout Supplements in 2026: Stimulant vs. Stim-Free

Pre-workout is one of the few supplement categories where the first decision isn’t brand or flavor — it’s whether you want caffeine in it at all. Most comparison articles skip straight to stimulant products and treat “pre-workout” as synonymous with “energy drink you take before lifting.” That’s true for most buyers, but not all of them.

Quick picks

• Stimulant pick: ProSupps Mr. Hyde Signature V2 — energy, focus, and 2g creatine in one scoop.
• Stim-free pick: EHP Labs OxyShred Non-Stim — the pump and focus ingredients without the caffeine.

Decide on stimulant vs. stim-free first

If you train in the morning or afternoon and have no caffeine sensitivity, a stimulant formula is the more conventional choice — it’s the format most gym-goers mean when they say “pre-workout,” and caffeine has the most consistent research behind it for perceived exertion and power output.

Stim-free makes more sense in a few specific situations: training at night, already near your daily caffeine ceiling from coffee, caffeine sensitivity or anxiety, or wanting a second session later the same day without stacking stimulants.

Neither format is “better” in the abstract — it depends on when you train and how you already use caffeine.

1. ProSupps Mr. Hyde Signature V2 — stimulant pick

Per the label, Mr. Hyde Signature V2 bundles energy, focus, and electrolyte ingredients with 2g of creatine per scoop, and the product is marketed as third-party banned-substance tested — relevant if you compete in a tested sport. It has a long track record, which is a reasonable sign that people keep buying it. How it feels still depends on your caffeine tolerance.

Worth knowing: the 2g creatine is a partial dose, not a replacement for a dedicated 5g/day creatine habit if that’s a separate goal for you.

2. EHP Labs OxyShred Non-Stim — stim-free pick

This is the same OxyShred line EHP Labs is known for, minus the caffeine. Per the label it’s positioned around the pump and shredding-support ingredients (L-carnitine, glutamine) without a stimulant base. It’s a smaller but well-reviewed listing (1,000+ ratings, 4.4 stars on the listing we checked) — useful specifically for the caffeine-avoidance use case rather than as a general “better” pre-workout.

What to actually look for on the label

Caffeine dose, if present. Anywhere from 150–300mg per serving is typical. If the label doesn’t state a number and just says “energy blend,” that’s a proprietary blend — skip it if you want to actually control your dose.

Citrulline or arginine for pump. Citrulline malate is generally considered the more effective of the two for perceived pump and blood flow.

Beta-alanine for the tingle. Harmless, but if you don’t like the skin-tingling sensation, look for a lower dose or a product that doesn’t include it.

Proprietary blends. If ingredients are listed under one umbrella weight instead of individually dosed, you can’t verify whether any single ingredient is at an effective dose.

What I’d skip

• Anything that won’t disclose exact milligram doses for its “energy blend.”
• Pre-workouts marketed primarily on flavor or packaging rather than an ingredient panel you can actually read.
• Doubling up stimulant pre-workout with a separately-caffeinated drink — that’s how people end up over 400mg of caffeine without meaning to.

Final answer

Pick based on when you train and how much caffeine you already have, not on flavor. Stimulant users start with ProSupps Mr. Hyde Signature V2. Anyone avoiding caffeine starts with EHP Labs OxyShred Non-Stim. Check the current label and your own caffeine tolerance before you buy. How it feels still depends on you.
