Why are suspiciously low prices a red flag?

Real quality control costs money — independent third-party testing, proper cold-chain handling, and genuine peptide content all add cost. When a price is far below market, something is usually being cut: the product may be underdosed (less actual peptide than labeled), a cheaper or wrong compound, untested, or degraded. As a rough market anchor, a common reference product like BPC-157 5 mg typically sells around $30–45; listings at a fraction of that are a frequent sign of a problem. The FTC's general rule applies — if a deal looks too good to be true, it probably is. Low price alone isn't proof of a scam, but it raises the bar: insist on a batch-specific, independently verifiable COA before trusting an unusually cheap listing.
