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.
03Analytical identity
Studied in combined incretin receptor models in vitro.

04In the lab
GLP-2 TZ and GLP-3 RT are each studied on their own pathways in laboratory research. This blend combines them in one vial; the map shows the best-characterized pathway reported for each.
Blend
GLP-2 / GLP-3Blend of GLP-2 TZ and GLP-3 RTBiased GLP-1R signal
Endpoint studied
Favored cAMP over beta-arrestin at GLP-1R; beta-arrestin1 did not limit its insulin response in islets.
Willard 2020 · PMID 32730231Fat tissue remodeling
Endpoint studied
Lower lipogenesis, more fatty acid oxidation and mitochondrial function, less inflammatory and fibrotic signaling.
Li 2026 · PMID 41964043Pathways as reported in the cited laboratory studies, for each compound in the blend. For in-vitro research use only.
05Research history
5 milestones, each linked to its PubMed record
GLP-2 TZ · JCI Insight
Engages the GIP receptor more than the GLP-1 receptor; at GLP-1R it favors cAMP over beta-arrestin recruitment.
PubMed · PMID 32730231GLP-2 TZ · The 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 34003802GLP-2 TZ · Proceedings 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 35333651GLP-3 RT · STAR Protocols
A protocol to grow human fat cells from preadipocytes and measure lipolysis induced by GLP-3 RT or GIP.
PubMed · PMID 37178114GLP-3 RT · Endocrine
In a diabetic kidney disease model it lowered NLRP3, caspase-1 and TNF-alpha, plus fibronectin, alpha-SMA and collagen I.

About GLP-2 / GLP-3, its certificate and your order.
Email [email protected], Monday to Friday. A person replies within one business day.
The current released lot, SA-G23-2610. 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.
