Tirzepatide is a dual GIP and GLP-1 receptor agonist. In the research supply chain it is the most heavily stocked incretin after semaglutide, and because more labs synthesize it, the per-milligram spread between vendors is narrower than on retatrutide.

ZestyRat Research, at $4.67 per milligram. That is 7% below the next-cheapest vendor on the board. The vendor our readers order from most, and every reader order has shipped. Ships the same day on orders placed before 3pm ET, USPS Priority. A free researcher account (21+) is set up once at checkout.
Across the vendors we index: 10mg, 20mg, 30mg. Larger vials are almost always cheaper per milligram, which is why the table above is sorted on that column rather than on sticker price.
This is the compound where vial size does the most work. Stepping from a 10mg vial to a 30mg vial cuts the per-milligram cost by roughly a third at the same vendor. Compare the 30mg rows before you conclude one vendor is cheaper than another.
