Evolve Peptides tirzepatide (GLP-2 TZ): what to know before you order
Evolve Peptides tirzepatide is sold as GLP-2 TZ in six sizes, from 5mg to 60mg. Here is how tirzepatide works, what the big trials found, which lab reports are in the photos and how to pick a size.
What is Evolve Peptides tirzepatide?
GLP-2 TZ is lyophilized tirzepatide in a sealed glass vial. Tirzepatide is a 39-amino-acid peptide developed by Eli Lilly that activates two gut hormone receptors, GIP and GLP-1. A fatty acid side chain lets it bind albumin in the blood, which stretches its half-life to about five days.
Lilly sells it as Mounjaro for type 2 diabetes and as Zepbound for weight management. GLP-2 TZ isn’t either of those medicines. It’s research material.
Evolve Peptides tirzepatide sizes and prices
- GLP-2 TZ 5mg: $74.90, about $14.98 per mg
- GLP-2 TZ 10mg: $119.90, about $11.99 per mg
- GLP-2 TZ 15mg: $149.90, about $9.99 per mg
- GLP-2 TZ 20mg: $179.90, about $9.00 per mg
- GLP-2 TZ 30mg: $229.90, about $7.66 per mg
- GLP-2 TZ 60mg: $389.90, about $6.50 per mg
The 60mg vial costs less than half as much per milligram as the 5mg. For a short study or a first look at the compound, start small. For longer work, the 30mg or 60mg vial saves money, as long as the mixed solution gets used within about four weeks.
Lab reports for GLP-2 TZ tirzepatide
GLP-2 TZ listings carry a Chromate certificate of analysis in the photos, with identity, HPLC purity and endotoxin results, and several sizes add a separate endotoxin report from a kinetic LAL assay. Click any image on the product page to zoom in on the numbers.
How tirzepatide works
GIP and GLP-1 are incretins, hormones the gut releases after a meal. Both push the pancreas to release insulin when blood sugar is high. GLP-1 also slows stomach emptying and acts on appetite centers in the brain. Tirzepatide is built on the GIP sequence and tuned to hit the GLP-1 receptor as well, so one molecule covers both pathways.
Tirzepatide research: what the trials found
The SURMOUNT-1 trial, published in the New England Journal of Medicine in 2022, followed adults with obesity for 72 weeks. Average weight loss at the highest dose was about 21%. The SURPASS trials looked at blood sugar control in type 2 diabetes. For the papers, start with this PubMed search for tirzepatide.
Tirzepatide sits between semaglutide (GLP-1 S), which targets GLP-1 alone, and retatrutide (GLP-3 RT), which adds the glucagon receptor. Our Evolve Peptides retatrutide guide covers the triple agonist.
Choosing an Evolve Peptides tirzepatide size
Work out how much your study will use over four weeks, since that’s how long a mixed vial lasts in the fridge. If that’s under 10mg, the 5mg or 10mg vial avoids waste. If it’s more, the 20mg, 30mg or 60mg vials cost less per milligram and mean fewer reconstitutions.
Reconstituting and storing tirzepatide
Add bacteriostatic water slowly down the inside of the vial and swirl until it’s clear. A 10mg vial with 2ml gives 5mg/ml. Every product page has the full table, and our reconstitution guide explains the math. Keep sealed vials cold and mixed vials in the fridge for up to 28 days.
