Overview
Tirzepatide is a synthetic peptide that functions as a dual pathway agonist, designed as a once-weekly investigational compound studied in preclinical laboratory models for receptor-mediated signaling and modulation of downstream cascades.
History
Tirzepatide was synthesized as a novel investigational dual agonist with balanced activity at two pathway targets, expanding earlier work on single agonists.
Structure and mechanism
Tirzepatide is a 39-amino-acid synthetic peptide engineered as a dual agonist with balanced activity at two distinct receptor targets. Like semaglutide, it carries a C20 fatty diacid moiety that supports albumin binding and a once-weekly profile, but its sequence is built around simultaneous engagement of both receptor pathways rather than one.
In laboratory models the compound is studied for the synergistic signaling that emerges from co-activating two pathways at once — receptor binding balance, biased agonism, and downstream cascade dynamics that single-pathway agonists don't reproduce. That dual-pathway behavior is why tirzepatide is frequently used as a reference compound in comparative research.
Reconstitution and handling (research use)
Wholesale tirzepatide ships as a lyophilized powder. For in-vitro work it is reconstituted with bacteriostatic or sterile water, with diluent volume selected to reach the concentration a given assay requires. Lyophilized material is generally held at -20°C and protected from light; reconstituted solution is refrigerated at 2–8°C and used within the study's working window.
These are general laboratory handling notes for a chemical reagent — not directions for human or veterinary use.
Wholesale sourcing notes
Tirzepatide is stocked in 10 mg, 20 mg, 30 mg, and 60 mg presentations. Every lot is US-sourced and independently verified by a third-party lab for identity, purity, and quantitation, with a per-lot COA included in every order.
Every dose carries three published prices, set by the order's total kits (mix and match): one for 1–9 kits (the minimum is 3 kits per order, mix and match across doses and compounds), a lower one at 10–99 kits, and the volume price at 100 kits (1,000 vials) or more. All three are listed in the price table on this page.
Buying Tirzepatide in Bulk
Tirzepatide is for sale here to qualified wholesale buyers as a lyophilized research peptide, in 10mg, 20mg, 30mg and 60mg vials packed ten to a kit. Pricing for every dose is published below, a per-lot certificate of analysis is included with every order, and in-stock orders ship from the US the same business day when paid before the daily cutoff.

Tirzepatide for sale by dose: 10mg, 20mg, 30mg and 60mg
All four doses are sold in kits of 10 vials. The table above shows the price of each kit, what that works out to per vial and per milligram, and the lower price that applies at volume, so the doses can be compared directly before you order.
Most buyers carry more than one dose. The minimum is 3 kits per order, mix and match, so a first order can be 3 kits of a single dose, or combine 10mg, 20mg, 30mg and 60mg kits with semaglutide, retatrutide and other compounds.
How to buy tirzepatide in bulk
Bulk tirzepatide is ordered online, right on this page. Choose the doses and number of kits you need and add them to your order. At checkout you enter your business details and shipping address and choose how you would like to pay: wire, ACH, Zelle or card.
