Everything Vyvata knows about this product — the score, the evidence, the FAQ, and where else to find shopper reviews. No hidden data. Every vendor is scored on the same published rubric — no brand can pay for placement. Read the rubric →
"Vemax Herbal Extract Blend" is an entirely undefined proprietary formulation — the label discloses no ingredients other than "herbal extract blend" and the halal certification. This is the most severe form of proprietary blend: not just missing per-active mg, but missing the ingredients themselves. A buyer cannot know whether the product contains 30 different herbs or one, whether it targets libido/energy/stress/immune, or whether any of the actives are present at studied doses. The male-enhancement category (which Vemax appears to belong to, based on the separate "Vemax L-Arginine" SKU in the lineup) has documented PDE-5 adulteration risk in unregulated overseas products. Auto-failed under proprietary_blend_hides_dose (extreme case) and misleading_naming.
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.

The Vyvata score measures product integrity against a published rubric, not customer sentiment. Vyvata does not aggregate, republish, or license third-party reviews — the links below open search pages on their respective platforms.
Every VSF-related metafield surfaced verbatim. Nothing hidden. If you spot data that looks wrong, let us know.
Every score is set from the published rubric, audit-logged, and rescored whenever new evidence emerges (published trials, updated labels, third-party testing releases). Every vendor is scored on the same criteria — no pay-to-play. See our editorial-independence disclosure for the full policy, including brands with an editorial relationship to this site.
