Science you can verify.

CompletePeptides was founded in 2019 by a team of biochemists and pharmacologists who had spent years sourcing research compounds — and consistently encountered the same problem: suppliers who couldn't tell you where their product came from, what was in it, or how it was made.

We built CompletePeptides to be the supplier we always wished existed. Every compound is synthesised under controlled conditions, purified to pharmaceutical-grade standards, and independently verified before it reaches a researcher's bench.

Based in Australia, we maintain full traceability from raw amino acid precursor to final lyophilised vial. Our Certificate of Analysis is a batch-specific, third-party-generated record you can verify.
