One contaminated lot ends a career and a contract.

For products sold to athletes, contamination is not a quality issue that gets resolved with a credit note. A positive test ends sponsorships, voids retailer agreements and removes the product from every team and institutional channel at once. The controls that prevent it sit in sourcing and manufacturing, not in finished product testing alone.

WHERE CONTAMINATION ENTERS

Rarely the ingredient you were worried about.

Cross-contamination in shared facilities, carryover on shared equipment, adulterated or substituted raw materials, and botanical extracts with variable composition account for most positives. The formula is usually clean. The supply chain is where the risk lives, and it is traceable only if the documentation was built to trace it.

WHAT WE ASSESS

Four layers.

Ingredient and supplier risk

Source material, extract characterisation, supplier history, and which inputs carry genuine banned substance exposure rather than theoretical exposure.

Manufacturing site controls

Shared lines, changeover procedures, segregation, cleaning validation and whether the site has handled anything that would be a problem to carry over.

Traceability

Whether a finished lot can be traced back to raw material lots, and whether the documentation would survive scrutiny after a positive result rather than before one.

Claims and athlete-facing copy

Sports claims, performance language and the difference between what a certification permits you to say and what the marketing team has written.

CERTIFICATION

Readiness, then certification.

Certification programs test finished product and audit the site. They do not fix a supply chain that cannot be documented. We prepare the sourcing, documentation and site controls so that certification is a confirmation rather than a discovery, and coordinate the pathway from there. See our NSF Certification page for the certification process itself.

WHO THIS IS FOR

Anyone selling into sport.

Sport and performance brands

Pre-workout, creatine, protein, hydration, recovery and nootropic brands selling to teams, collegiate programs, professional athletes or retailers who require certification as a condition of listing.

Have the supply chain reviewed before the test.

Bring us the formula, the supplier list and the manufacturing site. We will tell you where the exposure sits and what has to be documented before certification.
