Dark Labs Creatine 500g (Expired 06/2026)

Six-dimension breakdown

Why this scored 32/100

This SKU carries an expiration date of 06/2026 and is being listed for sale on 2026-08-29 — two months past its stated shelf life. That is the entire finding. Creatine monohydrate itself is one of the most stability-tested supplement raw materials in the category (moisture is the primary degradation vector, and dry powder in a sealed container remains stable for years past printed dates in most tested lots), so the product may well still be efficacious. But selling an expired product with the expiration status disclosed in the product title and no updated third-party lot testing is a listing-integrity problem independent of the ingredient. There is also no product description, no dose disclosure, no confirmation of monohydrate versus a less-supported salt form (creatine HCl, ethyl ester, etc.), no third-party purity certification, and no publisher COA for the specific lot being sold post-expiry. Rejected as a listing on safety-and-integrity grounds. Vyvata's rule of thumb: a supplement past its printed expiration is not listable regardless of chemical stability, because the consumer contract implied by the expiration date has been broken by the seller. Would become listable at Standard 60-68 if replaced with a current-dated Dark Labs Creatine SKU that discloses form (creatine monohydrate), dose (5 g per scoop), and per-lot COA.

Evidence & sources

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.

How to read the Evidence dimension

• 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
• 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
• 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
• 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
• 0–19: No credible evidence base or unverifiable claims.
