Zepbound vs Compounded Tirzepatide: $449 or $69 a Month

12 months of Zepbound or compounded tirzepatide

What Zepbound costs without insurance

Lilly sells the Zepbound KwikPen to cash buyers through LillyDirect, priced by dose: $299 a month at 2.5 mg, $399 at 5 mg, and $449 at 7.5 mg and above as long as each refill is bought within 45 days of the last. Miss that window and 7.5 mg costs $499 and the 10 to 15 mg doses $699.

With commercial insurance that covers Zepbound, the savings card can bring a fill down to $25, capped at $100 a month and $1,300 a year, and it expires on December 31, 2026. Lilly Cares, Lilly's free-medicine program, does not include Zepbound. On Medicare Part D, the GLP-1 Bridge puts Zepbound for weight management at no more than $50 a month for people who qualify. The list price tops out at $1,086 a fill.

Zepbound or compounded tirzepatide over 12 months

One month at 2.5 mg ($299), one at 5 mg ($399), then ten at $449 on 7.5 mg or higher, refilled on time. That comes to $5,188 for a year of Zepbound. The same 12 months of compounded tirzepatide costs $828 at the cheapest seller and $2,988 at the middle price, which keeps $4,360 or $2,200 in your pocket.

Zepbound comes from Lilly as an approved KwikPen or vial in six strengths, 2.5 to 15 mg. Compounded tirzepatide is the same molecule prepared by a licensed pharmacy for a named patient, without FDA approval of the finished product, so its strength and sterility rest on that one pharmacy's work.
