Trash Files: Vendors Who Hide Their Risks

An independent dossier documenting peptide distributors whose sterility and endotoxin disclosures fall short of what buyers need.

Trash Files tracks distributors that expose researchers to undisclosed contamination risks. Every claim here is either sourced and attributed, or labeled as unresolved.

Published allegations claim Kcompounds shipped toxic substances in exchange for profit. These are reported concerns, not verified findings.

Buyers have reason to treat this vendor with extreme caution. No independent third-party lot assay or endotoxin certificate has been verified for its products, and the vendor's sterility disclosures are not publicly documented. Until those records are produced, the safest course is to avoid the source.

Without batch-level sterility results, buyers cannot tell whether a vial is free of microbial contamination. Silence on this point is itself a disclosure failure.

Endotoxin levels are rarely reported by distributors that avoid publishing results. Without them, injection-related risk cannot be assessed.

Missing certificates of analysis are the clearest signal. If a vendor cannot produce a current COA tied to a specific lot, treat every claim it makes as unverified.

Avoid any vendor that withholds sterility, endotoxin, or lot-level documentation. Until a claim is independently substantiated, it remains unproven.
