02Verify your vial

Three steps from label to lab.

  1. 01Scan the label

    Every vial label carries a QR code. Point your phone camera at it.

  2. 02Land on its record

    The code opens that lot's certificate with every assay value. No phone? Type the lot from your packing slip on Verify a lot.

  3. 03Check it with the lab

    Each signed certificate links to the lab's own verification page, so the report can be confirmed independently of us.

04In the lab

How GLP-1 S is studied to work.

GLP-1 S is a GLP-1 receptor agonist whose fatty acid chain binds albumin, giving a long half-life with nanomolar GLP-1R affinity in lab studies. Cryo-EM shows it contacts the receptor like native GLP-1, and it reaches brain GLP-1R sites near the ventricles.

Compound

GLP-1 SC-18 diacid-acylated Aib8 GLP-1 analog

  1. Albumin binding

    Receptor and albumin assays

    • Fatty acid
    • Albumin
    • GLP-1R

    Endpoint studied

    Long plasma half-life

    GLP-1R affinity of 0.38 nM, higher albumin affinity, and a 46-hour plasma half-life in a laboratory model.

    Lau 2015 · PMID 26308095

  2. Receptor structure

    GLP-1R-Gs complexes

    • GLP-1R
    • Gs protein

    Endpoint studied

    Active receptor complex

    Cryo-EM structures: peptide contacts like native GLP-1, with different receptor and peptide motions.

    Zhang 2021 · PMID 34260945

  3. Brain access

    Brainstem and hypothalamus

    • GLP-1R
    • c-Fos

    Endpoint studied

    Brain area activation

    Entered via circumventricular organs, not across the blood-brain barrier; c-Fos rose in 10 brain areas.

Email supportContact page
01Which lot will I receive?

The current released lot, SA-G1S-2610. Scan the QR code on the vial label to open its certificate. The lot number is also on your packing slip, and the full certificate is here.

02Is the certificate real, and can I check it?

Every certificate is issued by an independent laboratory. Each lot has its own public record page with every assay value, and a link to verify the report on the lab's own site once the signed PDF is posted.

03Why does net content show more than 20 mg?

Vials are filled slightly over the labelled mass so that every vial meets it. Net content is measured on each lot and published as a number, not a pass.

04What if the vial arrives without vacuum or damaged?

Email [email protected] within 7 days with your order number and a photo and we will replace it.

05When will it ship?

Orders by 2 PM ET on a weekday ship the same day, with tracking emailed when the label prints.

06Is GLP-1 S for human use?

No. It is sold strictly for in-vitro laboratory research and is not for human or animal use of any kind.
