The Journal
Ten data-led investigations into what tirzepatide costs, what it does, and how to check who is selling it to you. Every table and chart is computed from our published dataset.
The journal is where we do arithmetic the market would rather nobody did: cost per milligram, cost per percentage point of body weight lost, the three-year cost of FDA approval status, and what a prepaid discount is really worth against the sum it puts at risk.
Every figure regenerates from the same dataset that drives our price tables, so these posts do not go stale in the way a hand-written article does. Each carries a verification date and links to the primary sources.
