Honest about origin, independently verified

Reproducible research depends on knowing exactly what is in the vial. Most peptide sellers won't tell you where their material comes from — nearly all of it starts as bulk powder in China. We do the opposite: we tell you, and then we send every batch to an independent laboratory in the United Kingdom or Europe for purity and identity testing. The numbers you see are theirs, not ours, and the data ships with the material rather than sitting behind a request form.

Honest about origin

Most peptide material worldwide is synthesised in China. We buy raw materials from established Chinese manufacturers — the same source the entire market draws from. The difference is that we say so, and then we test every batch.

Independent laboratory testing

Every batch — not a periodic spot check — is sampled and tested by an independent laboratory in the United Kingdom or Europe. If a lot does not meet specification, it is not released.

  1. 01

    Sourced at origin

    Raw peptide material is purchased from established manufacturers in China — the same source as most of the world's research peptide supply. We don't hide that. We verify it.

  2. 02

    Independent sampling

    A sample is drawn from every finished batch and sent to an independent laboratory in the United Kingdom or Europe. The testing house is separate from the supplier and has no commercial interest in the outcome.

  3. 03

    Third-party purity determination

    Analytical RP-HPLC at 214 nm, performed by the independent laboratory, establishes the purity figure printed on the certificate of analysis. We publish the measured value, never a rounded marketing claim.

  4. 04

    Identity confirmation

    ESI or MALDI mass spectrometry confirms the observed molecular mass against the theoretical mass for the stated sequence, so you know the vial contains the peptide on the label.

  5. 05

    Physical characterisation

    Residual moisture by Karl Fischer, counter-ion content, and appearance are recorded for each lot.

  6. 06

    Release against the lot's own data

    The batch-specific certificate of analysis, HPLC trace, and mass spectrum accompany the shipment and are archived against the lot number for full traceability. Out-of-specification batches are not released.

Analytical characterisation confirms chemical identity and purity only. It does not establish safety, efficacy, or suitability for any use in humans or animals. All materials remain restricted to in vitro laboratory research.
