Why CBUM Thavage Pre?
- 305mg total caffeine per full serving (260mg anhydrous + 45mg extended-release) — sustained energy with a longer, smoother curve than single-source caffeine formulas
- 6g L-citrulline per full serving — a clinically studied dose for nitric oxide production, vasodilation, and training pump
- 3.2g beta-alanine — an effective dose for buffering lactic acid and extending muscular endurance during high-rep or high-intensity training
- 1.5g Nitrosigine® — a patented, peer-reviewed pump ingredient shown to improve vasodilation beyond citrulline alone; adds a meaningful second pump pathway
- 2.5g betaine anhydrous — supports muscle power output and hydration at the cellular level
- Alpha-GPC + Huperzine A cognitive focus stack — two of the best-studied nootropic compounds for training focus and mind-muscle connection
- Fully transparent label — every ingredient and dose disclosed; no proprietary blends
Who Is This For?
Thavage Pre is for experienced pre-workout users who want a complete, fully-dosed formula — not a budget product with underdosed actives hidden behind a proprietary blend. The 6g citrulline, 3.2g beta-alanine, 1.5g Nitrosigine, and 2.5g betaine are all at or near the doses used in peer-reviewed research. The cognitive stack (Alpha-GPC + Huperzine A) is a meaningful addition for athletes who struggle with 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, it is also the pre-workout CBum himself trains with.
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 — the extended-release caffeine fraction will remain active for several hours after dosing; avoid within 6 hours of sleep
- ✗ Athletes in tested competition who require NSF or Informed Sport certification — confirm compliance requirements with your sport's governing body 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
What's In It?
CBUM Thavage Pre uses a multi-system formula across four performance pillars. Energy: 260mg caffeine anhydrous for immediate stimulation + 45mg extended-release caffeine for a sustained tail, plus Bitter Orange and L-Tyrosine for additional adrenergic support. Pump: 6g pure L-citrulline for nitric oxide production + 1.5g Nitrosigine® (patented bonded arginine silicate) for a second, independent vasodilation pathway. Endurance: 3.2g beta-alanine for carnosine buffering + 2.5g betaine anhydrous for cellular hydration and power. Focus: Alpha-GPC and Huperzine A — two established nootropics for acetylcholine support and training cognition. AstraGin® is included as an absorption amplifier across the full ingredient matrix. The formula is fully transparent with no proprietary blends. Each tub contains 40 scoops (20 full 2-scoop servings).
