Banned Substance Checker

CheckPeak is an athlete-focused banned substance checker that helps you scan supplement labels and flag potential red flags fast. Upload an ingredient label, and CheckPeak extracts text and checks it against reference lists-highlighting suspicious matches and aliases.

Why a banned substance checker matters

For tested athletes, “I didn’t know” is rarely a defense. Labels can be confusing, blends can hide ingredient wording, and aliases can make a compound hard to spot. A banned substance checker is a fast screening step to reduce obvious risk before you commit.

What CheckPeak looks for

  • Potentially banned or commonly restricted substances (reference-based)
  • Aliases and alternate names used on labels
  • High-risk compounds that deserve extra verification
  • Ingredient matches that help you understand what’s inside

Best practices for safer decisions

  1. Scan the label for obvious red flags and suspicious wording.
  2. Confirm ingredients with your sport’s rules and trusted staff.
  3. Prefer products with reputable testing and clear labeling.
  4. Save scans to build a history and document due diligence.

CheckPeak is a screening tool and cannot guarantee compliance or product safety. Always confirm with your governing body and trusted guidance.
