GLP-2 TZ

Tirzepatide is the dual GIP/GLP-1 receptor agonist that reshaped incretin research before triple agonists arrived, and it remains the reference molecule in dual-incretin literature: glucose regulation, appetite signalling and metabolic pathway models. Supplied lyophilized in a 20 mg vial, each lot tested by HPLC and mass spectrometry, certificate on the thread before you pay.

Sold strictly as a reference material for laboratory research. We do not provide dosing information or administration instructions.

Every lot is tested by an independent laboratory using HPLC and mass spectrometry. The lot in stock right now is BV-2409-TZ20.

The certificate reports four things: identity, purity, water content and the absence of residual solvents. If any of the four is missing, the document is incomplete.

We send it in the WhatsApp thread before you pay, and it is worth knowing how to read it: how to read a COA.

The vial arrives sealed and lyophilized. Refrigerate it on arrival; for long holds, keep it frozen and away from light.

Handle it under laboratory conditions only. We do not supply reconstitution instructions, dosing information or injection supplies of any kind.

Confirmed before 2pm ET on a business day, it leaves the same day. Two to four business days across the continental US, with tracking. Flat $12, free over $200, in a plain box with nothing printed about the contents.

Unopened vials can be returned within 14 days of delivery. The full terms are here: shipping policy.
