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 →
'Testosterone Enhancement Capsules' from Vivalo is a small-vendor generic-named product with no manufacturer accountability trail publicly visible and no per-active mg disclosure — the product name itself functions as a health claim without label substantiation. This falls into the proprietary_blend_hides_dose autofail category, and the generic 'enhancement' framing risks unverified_medical_claim territory as well. No third-party testing, GMP disclosure, or ingredient standardization is documented. Would need to become a fully disclosed formulation from an accountable manufacturer with evidence-linked actives to leave Rejected.
Auto-fail rule triggered: Proprietary blend hides dose.
The product uses a proprietary or 'proprietary blend' formulation that hides per-ingredient dosages. Without knowing the amount of each active ingredient, users cannot verify whether the blend meets RCT-supported effective doses. See the full rubric →
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.

Testosterone Enhancement Capsules is a product from Vivalo, categorized under Men's health in the Supplements vertical. It is scored on the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product Vyvata lists.

Strongest: Safety at 40/100 (adverse-event profile, interaction risk, and dose ceiling) and Sustainability at 40/100 (sourcing practices, packaging, and corporate practice). Weakest: Transparency at 32/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Evidence at 30/100 (quality of published RCT support for the active ingredients at the label dose). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.
This product triggered the Vyvata auto-fail rule "proprietary_blend_hides_dose", which places it in the Rejected tier regardless of its scores on other dimensions. See the full explanation above and the methodology page for the current list of auto-fail rules.

Rejected products remain listed with reasons. Full methodology at https://vyvata.com/pages/methodology.
