LillyDirect (Zepbound) vs Oak Longevity
LillyDirect (Zepbound): The manufacturer's own cash channel for FDA-approved Zepbound single-dose vials: $299/month at 2.5 mg, $399 at 5 mg, and $449 for every dose from 7.5 to 15 mg through the Self Pay Journey Program — provided each refill lands within 45 days of the last, otherwise that refill reverts to $599–$1,049 by dose. This is the cheapest FDA-approved tirzepatide in the country and the benchmark every compounded price should be judged against. Oak Longevity: A small cash-pay telehealth program whose $133/month flat semaglutide price is currently the lowest month-to-month figure in our semaglutide index.

Questions people ask
Is LillyDirect (Zepbound) or Oak Longevity cheaper in 2026?
The tirzepatide and semaglutide verdict blocks above give the computed answer at the maintenance basis, with the verification status of each figure; the short version is that whichever program's all-in monthly number is lower on this page is cheaper on the evidence we hold today, and both rows carry capture dates so you can judge freshness.
What does LillyDirect (Zepbound) vs Oak Longevity miss that checkout will show?
Taxes, state availability, current promotions, and any dose surcharge introduced after our capture date. Screenshot the order summary before paying — that capture, not any comparison page, is your contract.
Why do you compare at the maintenance dose instead of the starting dose?
Because starter pricing lasts one or two months and maintenance pricing lasts the rest of the year; comparing starts against maintenances is the single most common way GLP-1 comparisons mislead.
