Tirzepatide 20 mg Peptide [GLP-1] Lyophilised Powder C₂₂₅H₃₄₈N₄₈O₆₈

Tirzepatide is a synthetic peptide that acts as a dual GIP/GLP‑1 receptor agonist.

Molecular formula:C₂₂₅H₃₄₈N₄₈O₆₈

Molecular weight: ~4813 Da

Amino‑acid length: 39‑residue peptide

CAS number:2023788‑19‑2

Peptide type: Dual GIP/GLP‑1 receptor agonist

It exists in two very different forms: the regulated prescription medicine (Mounjaro/Zepbound) and unregulated “research‑grade peptides.'

What “Tirzepatide Peptide” Can Mean

1) Prescription Tirzepatide 

• dual GIP/GLP‑1 receptor agonist used for diabetes and weight management.

• once‑weekly injection in regulated, pre‑filled pens.

• Prescription‑only in the UK (POM).

• Clinically tested dosing up to 15 mg weekly.

2) Research‑Grade Tirzepatide Peptide (sold online)

• lyophilised powder vials such as 10 mg & 20 mg vials 

• Marketed strictly for “research use only”—not approved for human use.

• Purity claims (≥99%) but not regulated like medicines.

• Requires reconstitution with bacteriostatic water before laboratory use

Reconstitute with BAC's Water Only
When reconstituting peptides, it is crucial to use bacteriostatic water (BAC) to ensure sterility and safety.

BAC water contains 0.9% Benzyl Alcohol and is bacteria-proof, making it the preferred choice for reconstitution.

This method helps preserve the integrity of the peptide and prevents contamination.

To reconstitute a peptide blend, follow these steps:
Disinfect both vials and the stoppers with alcohol wipes.

Measure the required amount of BAC water based on the dosage.
Mix the peptide powder with the measured BAC water in a sterile syringe.

Inject the solution into the vial and refrigerate at 2–8°C, protected from light.

Use the reconstituted solution within 4 weeks for best potency and safety.
