Who Is This For?
Thavage Pre is for experienced pre-workout users who want a complete, fully-dosed formula with every dose shown on the label. The focus stack (Alpha-GPC + Huperzine A) suits athletes who want training focus as much as energy. The 40-scoop format means you can dial in your own dose — half-scoop (153mg caffeine) for lighter sessions, full 2-scoop (305mg) for competition prep or heavy training days. For CBUM fans, RAW says Chris Bumstead personally designed this formula.
Who Is This NOT For?
- ✗ Stimulant beginners — start with a half scoop (153mg caffeine) to assess tolerance before moving to a full dose
- ✗ Evening trainers — 305mg of caffeine per full serving; avoid within 6 hours of sleep
- ✗ Athletes in drug-tested sport — check the full label against your sport's rules before use
- ✗ Anyone who dislikes beta-alanine tingles — the 3.2g dose will cause paresthesia in most users
- ✗ Under 18 — not intended for use by minors; consult a physician before use if you have any cardiovascular condition
