Tirzepatide

GLP-1 / GIP dual agonist Strong evidence 3 cited studies 34 live vendors

Tirzepatide is a synthetic dual agonist of the GLP-1 and GIP receptors under investigation for metabolic and endocrine research. Laboratories study its effects on glucose regulation and energy balance in preclinical models.

Evidence brief

Tirzepatide is a dual GIP and GLP-1 receptor agonist that has been studied in several phase 3 randomized controlled trials for type 2 diabetes and for weight management.

These figures are what pepmg still publishes about price: the floor, the middle, the spread and how many sources we track, computed from listings we captured first-party and refreshed on the same schedule as always. We no longer publish the individual listings or the sellers behind them.

Computed from 105 in-stock listings across 34 sources we captured first-party, with bulk vials, blends and statistical outliers excluded so the figures compare like with like. The spread is the highest tracked price divided by the lowest — how much the same milligram varies depending on where you look. The chart is the daily minimum; days we did not capture are left out rather than filled in.

Why compare $/mg for Tirzepatide?

Per-mg prices for tirzepatide vary due to differences in synthesis scale, purity levels, and vendor sourcing. Comparing prices helps researchers identify cost-effective options without assuming equivalence in quality.

Reading the COA

A third-party COA should confirm peptide identity via mass spectrometry and purity ≥98% by HPLC. Check for common adulterants like truncated sequences or residual solvents, and verify that the reported mg/vial matches the fill weight.

FAQ

What is the recommended storage condition for tirzepatide?
Store lyophilized tirzepatide at -20°C or below, protected from light and moisture. Reconstituted solutions should be refrigerated at 2-8°C and used within a short time frame to maintain stability.
What does a Certificate of Analysis (COA) contain?
A COA provides analytical data from an independent lab, including mass spectrometry for identity, HPLC for purity, and sometimes residual solvent or endotoxin levels. It verifies that the product meets specified quality parameters.
Why do prices for tirzepatide vary so much between suppliers?
Prices vary due to differences in synthesis methods, scale of production, purity grade, and vendor overhead. Lower-priced options may indicate lower purity or less rigorous quality control, so per-mg comparison helps assess value.

All products listed are sold by third-party vendors for laboratory and research use only (RUO). Where an FDA label or a peer-reviewed study has published a dose, pepmg reports it with the source named, because that is safer than guessing. It is a report, not medical advice and not a recommendation to use anything. pepmg sells nothing and ships nothing. Listings are price-tracking data, not endorsements.
