Why this scored 62/100
Inspired FSU Serum is a non-stimulant pre-workout centered on clinical-grade GlycoClear glycerol (99.7% pure) plus supporting pump ingredients. The glycerol-based pump category has real RCT support for hyperhydration and pump aesthetics at 1-1.5 g/kg dosing, and a clinical-grade glycerol source is a legitimate ingredient choice. Inspired publishes disclosed doses for the main actives (glycerol, plus typically citrulline and other pump ingredients). The non-stim format has legitimate use cases: late-day training where caffeine would disrupt sleep, stacking with a separate caffeine source, and users sensitive to stimulants. The overall documentation regime is above average for the space but not at NutraBio's level; per-lot COA publication is not documented. Safety at label doses is fine; glycerol requires adequate co-ingested water to work correctly. A defensible Standard-tier non-stim pre-workout; the ingredient selection is honest and the glycerol dose likely clears the clinical threshold.

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.
