Why this scored 40/100
Nutrex T-Up Max is a testosterone-support / T-booster from Nutrex Research — a legacy sports-supplement brand (established late 1990s, based in Florida) that operates at the mainstream sports-nutrition tier but whose testosterone-booster line has consistently used proprietary blends that hide per-ingredient milligrams. Prior Vyvata scoring of Nutrex testosterone-booster SKUs has consistently resulted in Rejected outcomes under the proprietary_blend_hides_dose autofail rule. The T-booster category more broadly has weak evidence for measurable testosterone-level increases in eugonadal men — most 'natural test boosters' produce statistically indistinguishable effects from placebo in controlled trials (tribulus, D-aspartic acid at typical doses, fenugreek — modest and inconsistent). Manufacturing scores marginally higher than the obscure-brand SKUs because Nutrex is at least a real US brand with cGMP facilities, but the proprietary-blend transparency failure is disqualifying under Vyvata's rubric.

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.
