Thorne Advanced Pre-Workout FAQ's
Everything you need to know before getting started.



Take it 15–30 minutes before your training session or race. Mix 2 scoops with at least 12 oz of water so the ingredients have time to absorb and kick in before your first effort.
No jitters — the 200mg of natural caffeine is paired with 200mg of L-Theanine, which calms the stimulant edge without blunting the energy. You may notice a mild tingling sensation from the Beta-Alanine, which is completely normal and harmless — it's just the compound doing its job.
Beta-Alanine increases carnosine levels in your muscles, which acts like a buffer against the acid buildup that causes that burning, slow-you-down sensation during hard intervals. More carnosine means you can sustain high intensity longer before fatigue forces you to back off.
Alpha GPC supports your brain's production of acetylcholine — the neurotransmitter that drives muscle contractions and mental focus. In plain terms, it sharpens the connection between your brain and your body so you stay dialed in when the effort gets hard.
Advanced Pre-Workout uses a more traditional performance stack — L-Citrulline, Beta-Alanine, Alpha GPC, and coffee-derived caffeine — optimized for power output, endurance, and focus. Pre-Workout Elite leans on adaptogenic mushrooms and Amazon-sourced guayusa extract for a lower-caffeine, more natural energy approach. Advanced is the better pick if you want clinically dosed, higher-intensity performance support.
