By Bulldog Nutrition Editorial Team | Updated: June 2026
Quick Answer
CBUM Thavage Pre-Workout by RAW Nutrition is a well-rounded, mid-stimulant pre-workout designed by 6x Mr. Olympia Chris Bumstead. At a single scoop, you get 130mg of caffeine, 3g of L-citrulline, and a nootropic stack including Alpha GPC and Huperzine A — making it a solid daily driver for Canadian lifters who want a reliable formula without going high-stim.

Available in Canada from Bulldog Nutrition, an authorized RAW Nutrition retailer, in 14 flavours with fast nationwide shipping.
If you've been watching fitness content on Instagram or YouTube in the past three years, you've seen Chris Bumstead's face on a supplement tub. What's less obvious from the marketing is whether CBUM Thavage actually backs up the hype. This review breaks down the complete formula, who it's best for, and whether it's worth adding to your pre-workout rotation as a Canadian buyer.

The Full Formula Breakdown
Energy and Stimulants
Thavage delivers 130mg of caffeine anhydrous per single scoop. This deliberately moderate dose means users can assess their tolerance and double-scoop to 260mg when they want more intensity. The formula also includes 50mg of bitter orange (synephrine). Important: bitter orange is on the NCAA banned substance list — avoid Thavage if you compete in NCAA-sanctioned sport.
Pump and Blood Flow
3g of L-citrulline supports nitric oxide production and muscle pump. Betaine anhydrous at 1.25g supports cellular hydration and power output.
Focus and Nootropics
Alpha GPC (200mg) and Huperzine A (50mcg) create a genuine cognitive stack supporting acetylcholine-based focus and mind-muscle connection. L-tyrosine at 1g rounds out the nootropic profile for sustained focus under stress.
Endurance
Beta-alanine at 1.6g provides carnosine buffering to delay muscular fatigue. First-time users will notice harmless skin tingling (paresthesia) — completely normal and fades with regular use.
Who Should Take CBUM Thavage?
- Intermediate to advanced lifters training 4–6 days per week
- Athletes who want a cognitive edge alongside physical performance
- Lifters who prefer flexible dosing over a fixed formula
- CBUM/RAW Nutrition brand followers
Who Should NOT Take CBUM Thavage?
- ✗ NCAA athletes — bitter orange (synephrine) is NCAA-banned
- ✗ Stimulant-sensitive individuals — synephrine amplifies the caffeine effect
- ✗ Evening trainers — caffeine + synephrine can disrupt sleep if taken within 6 hours of bedtime
- ✗ Under 18 — not intended for use by minors

Is CBUM Thavage available in Canada?
Yes. Bulldog Nutrition is an authorized Canadian and US retailer of RAW Nutrition, including the full CBUM line. Orders ship from Canada with fast nationwide delivery.
Is CBUM Thavage safe?
Thavage contains bitter orange (synephrine), which is not suitable for NCAA athletes or individuals with cardiovascular conditions. For healthy adults without stim sensitivities, it is generally well-tolerated. Always read the full label and consult a healthcare provider if you have any medical condition.
Can beginners take CBUM Thavage?
It's not the top recommendation for first-time pre-workout users. Beginners are better served starting with CBUM Essential Pre-Workout or Alani Nu Pre-Workout before graduating to Thavage.
What is the difference between CBUM Thavage and CBUM Essential?
Thavage is the higher-stimulant, more advanced formula — synephrine, stronger nootropics, and supports double-scooping up to 260mg caffeine. CBUM Essential is the cleaner option at 200mg caffeine with no synephrine — ideal for beginners or lifters who prefer a moderate stim level.
Is Bulldog Nutrition an authorized retailer of RAW Nutrition and CBUM products?
Yes. Bulldog Nutrition is an authorized Canadian and US retailer of RAW Nutrition. Every CBUM Thavage tub is sourced directly from the brand — 100% authentic, never grey market or counterfeit.
