TIRZ-2 30mg from Peptira is 30mg of TIRZ-2 (tirzepatide) in a sealed glass vial. TIRZ-2 is a dual GIP and GLP-1 receptor agonist. It’s sold for laboratory research only.

TIRZ-2 is our code name for tirzepatide. The compound inside the vial is tirzepatide, and everything below describes it.

About TIRZ-2 (tirzepatide)

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.

TIRZ-2 mechanism of action

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.

Published TIRZ-2 studies

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.

The primary literature is on PubMed, run by the US National Library of Medicine. Here’s a search for Tirzepatide studies to start from.

How TIRZ-2 compares

TIRZ-2 30mg is easier to place once you see it next to the compounds it’s usually compared with. TIRZ-2 adds GIP receptor activity to GLP-1, a dual agonist with larger weight effects than semaglutide in trials. The others:

• SEMA-1 acts on the GLP-1 receptor only and lasts about a week, the most studied compound in the group
• RETA-3 hits GLP-1, GIP and glucagon receptors, the triple agonist with the biggest phase 2 numbers so far
• Survodutide is another GLP-1 and glucagon dual agonist, in phase 3 for obesity and the liver disease MASH
• CAG-4 works through amylin receptors instead of incretins, often studied next to or with semaglutide

The main difference between these compounds is which receptors they hit. Pick the one that matches the receptor question in your study, and use the others as comparisons. See them all on our GLP-1 peptides page.

TIRZ-2 30mg quality notes

Every TIRZ-2 30mg vial carries a printed label with the compound name and amount, so you always know what you’re holding. If your lab needs batch paperwork for its records, contact Peptira support before you order and ask what’s available for the current batch.

Many labs run their own identity check when a new batch arrives. For peptides, purity is usually measured by HPLC, which separates a sample into its parts and reports the main compound as a share of the total. Mass spectrometry is often run alongside it to confirm the molecular weight.

Write the order date and the vial details into your lab notes. If a result looks odd later, you can tie it back to the exact material you used.

How to reconstitute TIRZ-2 30mg

Here’s the math for 30mg of powder:

• 2mL of bacteriostatic water gives 15mg/mL
• 3mL of bacteriostatic water gives 10mg/mL
• 5mL of bacteriostatic water gives 6mg/mL

Choose the volume that suits your measurements. Mark the vial with the concentration and date so nobody has to guess later.

Most labs use sterile bacteriostatic water. We stock bacteriostatic water in 3mL, 10mL and 30mL sizes. Warm the sealed vial to room temperature, add the water slowly along the glass wall and swirl gently until it’s clear. Never shake it.

Storing TIRZ-2 30mg

Store sealed vials of TIRZ-2 30mg in the freezer at -20°C, out of direct light. Mixed solution goes in the fridge at 2 to 8°C and should be used within about 28 days.

Let a frozen vial warm up to room temperature before you open it. Cold glass pulls moisture out of the air, and moisture is what degrades dry peptide.

TIRZ-2 sizes compared

• TIRZ-2 10mg: $89.00, about $8.90 per mg
• TIRZ-2 20mg: $129.00, about $6.45 per mg
• TIRZ-2 30mg (this page): $159.00, about $5.30 per mg
• TIRZ-2 60mg: $199.00, about $3.32 per mg

For longer projects a larger vial like TIRZ-2 30mg means fewer vials to mix and fewer reorders.
