Description
GLP-2 TZ 15mg from Evolve Peptides is 15mg of GLP-2 TZ (tirzepatide) in a sealed glass vial. GLP-2 TZ is a dual GIP and GLP-1 receptor agonist. It’s for in-vitro and lab research only.
GLP-2 TZ (tirzepatide) at a glance
Tirzepatide is a 39-amino-acid peptide from Eli Lilly that activates two receptors, GIP and GLP-1. A fatty acid side chain lets it bind albumin, so its half-life is about five days. It’s approved as Mounjaro for type 2 diabetes and as Zepbound for weight management.
How GLP-2 TZ works
Tirzepatide activates two incretin receptors. GIP and GLP-1 are both released by the gut after eating, and both push the pancreas to release insulin when glucose is high. GLP-1 also slows stomach emptying and acts on appetite centers in the brain.
The molecule is built on the GIP sequence and tuned to hit the GLP-1 receptor as well. It leans toward GIP in binding strength. A C20 fatty diacid lets it ride on albumin, so it lasts days instead of minutes.

What the research says about GLP-2 TZ
The SURMOUNT-1 trial (New England Journal of Medicine, 2022) reported average weight loss of up to about 21% over 72 weeks at the highest dose. The SURPASS trials covered blood sugar control in type 2 diabetes.

How to reconstitute GLP-2 TZ 15mg
Concentration is just the amount in the vial divided by the water you add. With 15mg in this vial:
- 1ml of bacteriostatic water gives 15mg/ml
- 2ml of bacteriostatic water gives 7.5mg/ml
- 3ml of bacteriostatic water gives 5mg/ml
Pick the volume that keeps your own calculations simple, then write the concentration and the mixing date on the label.
Use sterile bacteriostatic water. Warm the sealed vial to room temperature first so no condensation gets in, add the water slowly along the glass wall, and swirl gently until it’s clear. Never shake.
Storing GLP-2 TZ 15mg
The dry powder keeps best cold: 2 to 8°C in the fridge, or -20°C for long-term storage. After reconstitution, store it in the fridge and finish it within roughly four weeks.
GLP-2 TZ 15mg lab reports and purity
We’ve put the lab paperwork for GLP-2 TZ 15mg in the image gallery:
- A certificate of analysis with identity, measured quantity and HPLC purity. The Chromate reports also cover sterility and heavy metals.
- An endotoxin report from a kinetic LAL assay.

Common questions about GLP-2 TZ 15mg
How much is in the GLP-2 TZ 15mg vial?
15mg of lyophilized powder. The amount is printed on the label.
Is GLP-2 TZ the same as tirzepatide?
Yes. GLP-2 TZ is our product name for tirzepatide research material, and the lab reports in the photos identify it as tirzepatide.
Which size should I buy?
Pick by how much you’ll use. Bigger vials cost less per milligram, smaller ones mean less sits open in the fridge. The size comparison above lists every GLP-2 TZ option.
Is GLP-2 TZ 15mg lab tested?
Yes. The lab reports are in the product photos, so you can check purity before you order.
What do I mix GLP-2 TZ 15mg with?
Sterile bacteriostatic water. The reconstitution section above shows the concentration for each volume.
