Includes Access to Workout App
  • 450mg total caffeine — 350mg anhydrous plus 100mg zumXR extended-release: Immediate onset from caffeine anhydrous with a sustained tail from the extended-release compound — engineered for experienced athletes who need more intensity than standard pre-workouts deliver.
  • 6g L-Citrulline for pump and blood flow: Full clinical dose supports nitric oxide production, improving muscle nutrient delivery and reducing fatigue during high-volume training sessions.
  • Focus stack — 350mg Alpha-GPC, 600mg Lion’s Mane, 300mg RhodioPrime Rhodiola: Acetylcholine precursor for neuromuscular output, nerve-based cognitive focus, and adaptogenic mental clarity for tunnel-vision concentration under heavy load.
  • Not for beginners — tolerance assessment required: High stimulant dose demands a half-serving tolerance test before using a full dose. Do not combine with additional caffeine sources or use within 8–10 hours of intended sleep time.

Historic High-Stim by Historic Labs is their maximum-intensity pre-workout — engineered for experienced athletes who have built a tolerance to standard formulas and need more stimulant output.

• 450mg total caffeine: 350mg anhydrous for immediate onset + 100mg zumXR extended-release for sustained energy across longer training sessions without a sharp drop-off
• 6g L-Citrulline: full clinical dose for nitric oxide production, improved blood flow, and reduced muscular fatigue during high-volume work
• 600mg Lion's Mane Mushroom and 300mg RhodioPrime Rhodiola: cognitive focus and adaptogenic mental clarity for tunnel-vision concentration
• 350mg GeniusPure Alpha-GPC 90%: acetylcholine precursor for mind-muscle connection and power output
• 3.2g CarnoSyn Beta-Alanine: muscular endurance and fatigue buffering under load
• 2g HydroPrime Glycerol: intracellular hydration and pump volume
• AstraGin 50mg: absorption enhancer for full bioavailability of the formula

Flavor: Sour Gummy. 25 servings per container.

This is a high-stimulant product. Start with half a serving to assess tolerance. Do not stack with additional caffeine sources. Not recommended for afternoon or evening training.

Q: How does the 450mg total caffeine break down in this formula?
A: Historic High-Stim contains 350mg caffeine anhydrous for immediate onset plus 100mg zumXR extended-release caffeine. The extended-release component activates over a longer window — typically 2–4 hours after the anhydrous caffeine peaks — which smooths the energy curve and reduces the sharp drop-off common in single-source caffeine products.

Q: What is the recommended first dose for someone new to Historic High-Stim?
A: Start with half a scoop on a training day (not a rest day) to assess tolerance. Do not stack with coffee, energy drinks, or other stimulants on your first use. Wait at least two weeks of half-scoop use before trying a full scoop.

Q: What does L-Citrulline at 6g actually do compared to lower-dose products?
A: 6g is the dose consistently used in clinical research demonstrating significant improvements in nitric oxide production and blood flow. Many products use 3–4g to reduce cost. At 6g you get the blood flow and fatigue-reduction benefits that the research is actually based on.

Q: Is this suitable for afternoon training?
A: No — with 450mg total caffeine including extended-release compounds, this product will meaningfully affect sleep if taken within 8–10 hours of your intended sleep time. Morning or early afternoon training only.
