Full walkthrough — from picking ingredients to matching your workout.
Every tool you need.
Nothing you don’t.
Surge cuts through the bro-science and backs every recommendation with real evidence.
Live Score Engine
Energy, Pump, and Focus meters update the instant you toggle an ingredient — a saturating curve so stacking smarter beats stacking more.
12 Ingredients. Real Evidence.
Every compound is rated Strong, Moderate, or Emerging based on actual human trials — not label claims. See the dose range and onset timing.
Workout Matching
Pick Heavy Push Day, HIIT, or Zone 2 Cardio and Surge auto-fills the right stack for that session's demands — caffeine timing included.
Goal-Based Personaliser
Set your goal (Strength, Pump, Endurance, Focus), caffeine tolerance, and stim preferences. Surge prunes the list to exactly what you need.
Dose & Timing Guide
See the recommended dose, minimum effective dose, and how many minutes before training each ingredient needs to be onboard.
Stack History Log
Save your best stacks with a name, replay them on the same workout, and track what combination actually hit hardest.
AI is next.

AI adjusts doses based on your logged training sessions, recovery notes, and caffeine tolerance drift over time.
