Thorne Advanced Pre-Workout
Most pre-workouts hit you like a sledgehammer — skin tingling, heart racing, then a crash that tanks the rest of your day. You've been there. Here's what most athletes don't realize: the best pre-workout isn't about the biggest caffeine jolt. It's about giving your body the right tools to perform smarter, harder, and cleaner — without the side effects that follow you off the field.
Thorne Advanced Pre-Workout is the exact formula trusted by athletes on over 100 professional sports teams who need real, verifiable performance without a dirty label.
Clean Energy Without the Crash 200mg of natural caffeine from coffee beans is paired with L-Theanine — an amino acid that smooths out the stimulant edge — so you get sharp, sustained focus without the jitters, the tingling skin, or the afternoon collapse that plagues most pre-workouts.
The Pump and Endurance Stack That Actually Works 5g of L-Citrulline opens up your blood vessels to flood muscles with oxygen and nutrients, while 3.2g of CarnoSyn® Beta-Alanine — the compound that buffers the acid buildup that causes that burning, stop-you-in-your-tracks sensation — lets you push harder before fatigue forces you to back off.
Mind-Muscle Connection 600mg of Alpha GPC supports production of the brain chemical that controls muscle contractions and mental focus, so your head is as locked in as your legs.
The caffeine and L-Theanine combination is one of the most well-researched stacks in sports nutrition. Caffeine sharpens focus and delays fatigue; L-Theanine keeps you calm and dialed in without the chaos. L-Citrulline converts to arginine in your bloodstream, boosting blood flow and delaying the point where lactic acid wins. B vitamins — B6 and B12 — round out the formula by supporting the energy pathways your cells depend on during hard efforts.
Mix: Combine 2 scoops with at least 12 oz of water or your preferred beverage. Timing: Drink 15–30 minutes before your workout or race. Pro Tip: First time using it? Start with 1 scoop to gauge how your body responds, then work up to the full 2-scoop dose for maximum output.
Thorne is trusted by over 100 professional sports teams and serves as a proud partner of U.S. National Teams. NSF Certified for Sport means every batch is tested against nearly 300 banned substances — so you can take it before competition and never think twice.
This isn't just another pre-workout. This is the clean, clinically dosed formula built for athletes who demand performance they can actually trust.
