Best Pre-Workout Supplements 2025
The pre-workout market is saturated with products that are mostly caffeine with proprietary blends hiding underdosed ingredients. A handful are genuinely well-formulated with clinically effective doses of ingredients that actually improve performance. Here's how to tell the difference.
Best Pre-Workouts Ranked
Transparent Labs BULK
Every ingredient fully disclosed with clinical doses. 8g L-Citrulline Malate, 4g beta-alanine, 2.5g betaine, 200mg caffeine paired with 100mg L-theanine for clean focus without jitters. This is what a pre-workout should look like. No artificial colors, no underdosed ingredients hidden in blends. Strawberry Lemonade and Peach Mango are excellent flavors.
C4 Original
The entry-level standard for a reason — accessible price, reliable 150mg caffeine, and a moderate dose of beta-alanine. Not as clinically dosed as Transparent Labs but a solid starting point for anyone new to pre-workout. You get 60 servings per tub, which means it's one of the cheapest cost-per-serving options available. Watermelon flavor is the classic choice.
Legion Pulse Stim-Free
Full clinical doses of all performance ingredients — without caffeine. Ideal for evening training, caffeine-sensitive individuals, or people already taking stimulants from other sources. Legion is one of the most scientifically rigorous supplement companies, with peer-reviewed citations for every ingredient. The pump and endurance benefits are real without the stimulant side effects.
Gorilla Mode
Not for beginners — 350mg caffeine per serving is aggressive. For experienced users who've built caffeine tolerance, Gorilla Mode delivers noticeable performance improvements with one of the highest citrulline doses on the market (9g). Full label transparency. Start with half a scoop to assess tolerance. Not recommended for people on blood pressure medications or GLP-1 users with cardiovascular concerns.
Kaged Pre-Kaged Elite
Informed Sport certified — tested for banned substances, important for athletes in tested sports. Uses fermented plant-based amino acids rather than synthetic. One of the most complete formulas available with creatine, BCAAs, citrulline, and electrolytes included. Premium price, but replaces several other supplements in one product.
