Methodology and sources.

Every statistic we publish on this site is defined here: what it measures, the time window it covers, and where the data comes from. External figures cite named sources. Vendor claims are labeled as vendor claims. If a number cannot be verified with a named source, we do not publish it.

A note on industry benchmarks

Some directional figures on this site, such as med spa GLP-1 patient lifetime values, membership price ranges, and per-unit injectable pricing, are industry and individual-practice benchmarks from marketing and consulting sources rather than peer-reviewed data. We present them only as industry benchmarks, never as Profit Zombies results. Self-reported agency performance claims found in third-party marketing are not reproduced on this site as fact.
