Raw Nutrition CBUM Series Thavage Pre-Workout

Six-dimension breakdown

Why this scored 60/100

Thavage is the flagship pre-workout in Raw Nutrition's CBUM Series (co-developed with 5x Mr. Olympia Chris Bumstead) and is one of the fully-disclosed high-stimulant formulas in the athlete-signature segment. The full label discloses individual doses: 8 g L-citrulline (above the 6-8 g clinical range for pump/endurance — genuinely well-dosed), 3.2 g beta-alanine (hits the ISSN position-stand dose for the tingle and chronic carnosine loading), 2.5 g betaine anhydrous (in the 2.5 g clinical range for power output; Cholewa 2013), 1 g L-tyrosine (below the 2-3 g clinical range for stress-cognition endpoints), 300 mg alpha-GPC 50% (yields ~150 mg alpha-GPC — well below the 600 mg cognitive dose), and a stimulant stack of ~275 mg caffeine anhydrous plus dicaffeine malate (Infinergy) — putting effective caffeine at ~325-340 mg per scoop. Formulation quality is genuinely above the market median for the category, and the athlete-brand co-development doesn't come at the cost of scientific rigor on citrulline, beta-alanine, and betaine. Weaknesses: alpha-GPC and tyrosine are under-dosed for their cognitive-effect ranges (present at what look like label-decoration doses); the ~330 mg total caffeine load is at the upper end for a single scoop; no third-party sport certification (Informed Sport / NSF) on this SKU. Manufactured in cGMP-registered US facility. Would move to Verified 70+ with Informed Sport certification, clinically-dosed alpha-GPC (600 mg) and tyrosine (2 g), and published per-lot COAs.

Evidence & sources

The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.

Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

How to read the Evidence dimension

• 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
• 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
• 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
• 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
• 0–19: No credible evidence base or unverifiable claims.
