02Verify your vial
Every vial label carries a QR code. Point your phone camera at it.
The code opens that lot's certificate with every assay value. No phone? Type the lot from your packing slip on Verify a lot.
Each signed certificate links to the lab's own verification page, so the report can be confirmed independently of us.

04In the lab
GLP-2 TZ is one acylated peptide that activates both the GIP and GLP-1 receptors. In cell studies it acts like native GIP at the GIP receptor, but at the GLP-1 receptor it favors cAMP over beta-arrestin, with less receptor internalization.
Compound
GLP-2 TZAcylated dual GIP and GLP-1 receptor agonist peptideReceptor cells and islets
Endpoint studied
Favored cAMP over beta-arrestin at GLP-1R; beta-arrestin1 did not limit its insulin response in islets.
Willard 2020 · PMID 32730231White adipose tissue
Endpoint studied
Raised insulin sensitivity via glucose disposal in white fat, even without GLP-1R; circulating BCAAs fell.
Samms 2021 · PMID 34003802Brown adipose tissue
Endpoint studied
Tracer studies: more BCAA and BCKA breakdown in brown fat, with higher alpha-ketoglutarate and malate.
Samms 2022 · PMID 35921984Pathways as reported in the cited laboratory studies. For in-vitro research use only.
05Research history
4 milestones, each linked to its PubMed record
JCI Insight
Engages the GIP receptor more than the GLP-1 receptor; at GLP-1R it favors cAMP over beta-arrestin recruitment.
PubMed · PMID 32730231The Journal of Clinical Investigation
In an obesity model lacking GLP-1R, it still raised insulin sensitivity through glucose disposal in white adipose tissue.
PubMed · PMID 34003802Proceedings of the National Academy of Sciences of the United States of America
Cryo-EM and simulations show how its fatty acid and sequence set its action: GIP-like at GIPR, distinct at GLP-1R.
PubMed · PMID 35333651Molecular Metabolism
It stimulated BCAA and BCKA catabolism in brown adipose tissue and raised several TCA cycle intermediates.

Email [email protected], Monday to Friday. A person replies within one business day.
The current released lot, SA-G2T-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.
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.
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.
Email [email protected] within 7 days with your order number and a photo and we will replace it.
Orders by 2 PM ET on a weekday ship the same day, with tracking emailed when the label prints.
