CBUM Thavage Pre-Workout Review: Ingredients & Science
CBUM Pre-Workout Review: Thavage Ingredients & Science
Chris Bumstead (aka CBUM), 6-time Mr. Olympia Classic Physique champion, became a co-owner of RAW Nutrition in 2021 and created Thavage Pre-Workout—a supplement that promises tunnel-vision focus, enhanced muscle pumps, and "thavage" energy.
This review unpacks each ingredient, compares Thavage to its competitors, and provides practical intake guidelines.
Quick Takeaways
- Two-scoop serving delivers 305 mg total caffeine (260 mg anhydrous + 45 mg extended-release) plus a hefty 6 g citrulline and 3.2 g beta-alanine.
- Clinically dosed Nitrosigine® (1.5 g) is backed by a 2020 peer-reviewed study showing improved vasodilation (Kim 2020). Separate studies demonstrate cognitive benefits from Nitrosigine supplementation.
- Combo of nootropics (alpha-GPC, l-theanine, huperzine A) smooths energy without a harsh crash.
- Powder is available in 15+ flavors; RTD cans supply 200 mg caffeine for grab-and-go convenience.
- Mid-stim formula: suitable for afternoon lifts if caffeine intake stops by ~2 p.m.; sensitive users can "Go Half Thavage" with one scoop.

Science Highlights
- Nitrosigine vs. Citrulline Malate – A 2020 study found that 1.5 g of Nitrosigine widened blood vessels (flow-mediated dilation) as effectively as 8 g of citrulline malate, indicating comparable pump potential (Kim 2020).
- Betaine & Body Composition – A six-week trial showed that 2.5 g/day of betaine improved bench-press volume and reduced body-fat percentage in experienced lifters (Cholewa 2013).
- Tyrosine for Focus Under Stress – A 2015 systematic review concluded that tyrosine supplementation can enhance cognitive performance in short-term stressful or cognitively demanding environments (de Jong 2015).

Key Takeaway
Athletes who prioritize full clinical doses—and can accommodate a moderate stimulant load—will find that Thavage outclasses many mainstream formulas, particularly in nitric-oxide support and cognitive stacking.
Flavor Line-Up (2025)
RAW Nutrition regularly releases new flavors—currently 15+ options from Dragon Fruit to 4-Peat Red Gummy. Based on aggregate customer reviews, popular picks include Rocket Candy for solo sipping and Peach Bum for mixing with creatine.
RTD cans come in Miami Vice, Christopher's Secret Stuff, and Strawberry Mango, each delivering 200 mg caffeine with zero mixing.
How to Use Thavage Safely
- Assess tolerance – Begin with 1 scoop (~153 mg caffeine) 30 minutes before training.
- Stack smart – The formula already supplies 6 g citrulline and 3.2 g beta-alanine; additional pump products are unnecessary.
- Mind bedtime – Caffeine's half-life is roughly five hours (FDA). Evening lifters may prefer the RTD (200 mg) or a half scoop to avoid sleep disruption.
- Stay hydrated – Ingredients such as betaine and taurine draw water into muscle cells; add 16–20 oz of fluid during the session.

Possible Side Effects
| Symptom | Likely Culprit | Mitigation |
|---|---|---|
| Skin tingles (paresthesia) | Beta-alanine | Harmless; split the dose or reduce to half scoop |
| Jitters & palpitations | 305 mg caffeine + synephrine | Limit to 1 scoop; avoid additional stimulants |
| Headache or nausea | Dehydration / empty stomach | Consume water and light carbohydrates pre-workout |

FAQs
Is Thavage vegan and gluten-free?
This requires verification directly with the manufacturer, as the ingredient sourcing and processing methods determine these claims.
Can Thavage be stacked with creatine?
Yes. Thavage lacks creatine, so taking 3–5 g creatine monohydrate daily pairs well.
Does Nitrosigine replace citrulline?
No. The combination may be synergistic; Thavage includes both for a comprehensive pump profile.
Are discounts available?
Major retailers like GNC, Amazon, and Walmart often run BOGO promotions or subscription savings. Check their listings for current offers.
