NutraKey Red Deer Antler Test, 120 Capsules

NutraKey Red Deer Antler Test, 120 Capsules is a product from PoorBoySupplements.com, 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.

38/100 overall — Rejected tier (0–49 band). Per-dimension breakdown: Manufacturing 45, Safety 45, Formulation 40, Sustainability 40, Transparency 35, Evidence 25. Scored as of 2026-08-24.

This is a combination testosterone-support product built around deer antler velvet, whose IGF-1 marketing claims have essentially no human RCT support (early Sleivert-era rugby study was negative, and no follow-up has established anabolic effect in healthy men). NutraKey's 'Test' line typically uses a proprietary blend without per-active mg disclosure, which is a transparency autofail under our rubric. Even setting the blend aside, the underlying evidence base for deer antler is animal-tier only. Would need to move to a fully disclosed formulation built around evidence-supported actives (KSM-66 ashwagandha, standardized Tongkat Ali/Physta or LJ100, boron 10mg) to escape the Rejected tier.

Strongest: Manufacturing at 45/100 (third-party testing, GMP compliance, and facility audit status) and Safety at 45/100 (adverse-event profile, interaction risk, and dose ceiling). Weakest: Transparency at 35/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Evidence at 25/100 (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.
