Medlly

Lab & transparency

Tested by lot, documented for the record.

Every Medlly research material ships with analytical documentation. Each production lot is sampled and tested by an independent third-party laboratory, and the matching Certificate of Analysis is published on its product page.

Verified, lot by lot

From synthesis to seal, follow the chain of custody.

Drag the playhead through every checkpoint a lot passes before it ships. The readouts are illustrative of the analytical record, not a specific lot.

Step 1 / Synthesis

The sequence is assembled one amino acid at a time, then cleaved and lyophilized into raw material.

SynthesisPurificationPurityIdentityCertificate

Testing is performed by independent third-party laboratories. Purity is reported as net peptide content, distinct from associated salts and water. For Research Use Only.

How it's tested

From production lot to published certificate

  1. 01

    Sampled

    A representative sample is drawn from every production lot before it's listed.

  2. 02

    Analyzed

    An independent third-party lab runs the full panel by HPLC and mass spectrometry.

  3. 03

    Documented

    Results are written into a Certificate of Analysis keyed to that lot number.

  4. 04

    Published

    The COA is posted on the product page and travels with the order, no email gate.

What we test

The standard analytical panel

Each lot is evaluated across five measures. The method for each is recorded on the Certificate of Analysis for that lot.

  • MS

    Identity

    Confirms the material matches the named compound.

  • HPLC

    Purity

    Reports the assayed fraction of the target compound.

  • MS

    Mass

    Verifies the measured molecular mass against the expected value.

  • LAL

    Endotoxin

    Screens each lot for bacterial endotoxin presence.

  • Visual

    Appearance

    Records the physical form and color of the lyophilized material.

Example Medlly Certificate of Analysis

The document

A signed certificate for every lot

The COA reports the analytical results for the exact lot you receive (identity, purity, mass, water content, and endotoxin) with the testing lab, dates, and lot number on the page. The document you read is the document for the lot in stock.

  • No email gate, viewable inline and downloadable
  • Lot number on the vial matches the certificate
  • Travels with the order for your records

Independent testing

Third-party laboratories

Testing is performed by accredited third-party laboratories that are independent of fulfillment. We do not self-certify results. A representative sample is drawn from each production lot and run through the analytical panel above.

Results are keyed to the lot number printed on the Certificate of Analysis. Because COAs are issued per lot, the document on a product page corresponds to the lot currently in stock. If you need the COA for a specific lot you already received, contact support with the lot number.
