GLP-2 TZ is this catalog's house designation, not a reference to glucagon-like peptide-2. The number is the GLP series and the letters are the compound: GLP-1 S is semaglutide, GLP-2 TZ is tirzepatide, GLP-3 RT is retatrutide. The certificate for each lot names it both ways — product "Tirzepatide", identity "GLP TZ".

Authenticity
Every vial carries a code
Scan the code on the label to pull up every published certificate for that compound — the same reports the third-party laboratory issued, batch by batch. Traceable from the laboratory that tested it to your bench.
Verify a batch →Verified, lot by lot
Per lot- ✓
Independently tested
Purity is quantified by reverse-phase HPLC and identity confirmed by mass spectrometry, by an outside laboratory rather than in-house.
- ✓
A certificate for your lot
The report that ships with your order describes the batch you received — not the product line, and not a representative sample.
- ✓
COA-backed replacement
If material does not match the certificate issued for its lot, we replace it or refund it. Send us the lot number and we will trace it.
- ✓
Tracked dispatch
Tracking is issued when the label is created, so the shipment is traceable from the moment it leaves us.
About this compound
What GLP-2 TZ is
GLP-2 TZ is tirzepatide — a 39-residue dual agonist of the GIP and GLP-1 receptors. Its backbone is derived from GIP rather than GLP-1, with aminoisobutyric acid at positions 2 and 13 blocking DPP-4 cleavage and a C20 fatty diacid enabling albumin binding. The reported half-life is roughly five days. Research endpoints center on metabolic and glycemic regulation through the two receptors together.

This compound is a long, flexible chain. Any single three-dimensional arrangement would be one of an enormous number it can adopt, so we do not show one. The sequence and the reference values beside this are the reliable description.

FAQ
Common questions about GLP-2 TZ
What is GLP-2 TZ?
+
GLP-2 TZ is tirzepatide — a 39-residue dual agonist of the GIP and GLP-1 receptors. Its backbone is derived from GIP rather than GLP-1, with aminoisobutyric acid at positions 2 and 13 blocking DPP-4 cleavage and a C20 fatty diacid enabling albumin binding. The reported half-life is roughly five days. Research endpoints center on metabolic and glycemic regulation through the two receptors together.
How should GLP-2 TZ be stored and reconstituted?
+
Store the sealed vial at -20°C, protected from light and moisture, and let it reach room temperature before opening so condensation does not form on cold powder. Keep reconstituted solution refrigerated and avoid repeated freeze-thaw cycles — solutions are far less stable than lyophilized powder.
Is GLP-2 TZ approved for human use?
+
No. GLP-2 TZ is supplied strictly for in-vitro laboratory research and development. It is not a drug, food, supplement or cosmetic, it has not been evaluated by the FDA, and it is not intended for human or animal consumption, ingestion, injection or any in-vivo use. Ordering confirms you are a qualified researcher or institution purchasing on that basis.
For research use only
Not for human or veterinary use. For in-vitro laboratory research only. These statements have not been evaluated by the FDA; this product is not intended to diagnose, treat, cure, or prevent any disease. Sold exclusively to qualified researchers and institutions.
