Angry Supplements is a real US-based nutraceutical brand carried at mainstream mass retail, and their 'Monster Test' testosterone booster is a familiar SKU. Marketing copy claims '100% natural and pure testosterone-boosting ingredients... tested to the highest standards and proven to work,' which is not supported by any published human RCT of the finished formula. The formula reliably layers tribulus terrestris, zinc, magnesium, and a proprietary blend of adaptogens/herbs at undisclosed doses. As noted for other T-boosters, tribulus has repeatedly failed to elevate testosterone in eugonadal men (Rogerson 2007, Neychev 2005), and zinc/magnesium only correct T levels in the deficient. 'Proven to work' language is a promotional overreach given the actual evidence base. Autofail on proprietary_blend_hides_dose. Manufacturing/safety are middling because the brand is real and mainstream-distributed, not because the specific claims are validated.
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.
