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 →
Lepigra is a Turkish libido/energy product combining maca (Lepidium meyenii) with ginseng — a mechanistically plausible pairing. Maca at 1.5-3g/day has RCT evidence for sexual desire in men and women (Gonzales 2002; Shin 2010 review) and may modestly improve sexual function without changing serum hormones. Ginseng at 200-400mg standardized Panax has small-trial ED evidence. But this SKU discloses neither per-active mg nor standardization percentages, and a 30-tablet count suggests a one-per-day format — meaning if the tablet holds 500mg total, the maca dose is likely 250-350mg, well below the 1.5-3g/day used in trials. Auto-failed under proprietary_blend_hides_dose. The libido/male-enhancement category compounds this with PDE-5 adulteration risk from small overseas brands.
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.
