We search specifically for the peptide you declare (for example, Retatrutide) by reverse-phase HPLC. Identity is confirmed when the main peak matches the retention time of a certified reference standard of the same peptide, run under the same conditions. Purity is the area % of the main peak; the content in mg is calculated against the reference standard of known concentration. Add mass confirmation (HPLC-MS) to also confirm the identity by molecular mass. Not sure of the exact peptide, or want to check for other substances beyond the one declared? See the Advanced impurity panel below.

Per sample, on top of the analysis.

Detects presence of Cd, Pb, Hg, As.

Details

TAMC & TYMC Control: This procedure detects the load of microbes and yeasts in the formula. The laboratory requests the delivery of supplementary sealed containers for processing. The standard turnaround window for this report is 15 days.

Details

Performed per USP <71> methods (excluding sampling requirements). Lead time is 18 to 20 business days due to the incubation time for growth and possible identification testing. A full vial is required for this test.

Details

Peptides and peptide blends: the sample is run by HPLC-MS, so the identity of the peptide is also confirmed by its molecular mass, in addition to purity and content. The mass spectrum is added to the certificate next to the chromatogram. Per sample.

Details

Complete access to all the background data of your sample, as exported by the instruments: the main analysis and any add-on tests on the same sample. Sent as a PDF annex (usually 6 to 12 pages) together with your certificate. Exporting everything takes the lab extra time: delivery takes 7 working days longer. Separate from the chromatogram on the certificate. Per sample.

What the price means

  1. 01

    One price per sample

    Every sample is priced on its own. Add-ons apply to the sample you add them to.

  2. 02

    No rush fees, no priority lane

    All samples follow the same queue and the same protocol.

  3. 03

    Bitcoin first, apps too

    Bitcoin through our own payment server, or other cryptocurrencies and Revolut, Wise and PayPal (subject to availability) through our partner Peer. Same price either way.

  4. 04

    Refund before check-in

    Before the sample reaches the lab you can ask for a refund of the analysis fee (network fees are not recoverable).

  5. 05

    Prices can change, your order doesn't

    Prices updated on 30 October 2026: peptide and steroid certificates now include the chromatogram, and peptide testing is €145. Orders and quotes placed before keep their price. Please check the current price before you order.
