Peptide Plug vs Regimen
Regimen is one of the closest feature competitors to Peptide Plug. Both track protocols, injections, side effects, labs and estimated levels, but they take different approaches to platforms, analytics and cost management.
Short version
Regimen is the stronger fit if you want native iOS and Android apps, Apple Health or Health Connect data, a 200+ item catalog and its Signals pattern engine. Peptide Plug is the stronger fit if you want an installable browser app with live cost-per-dose and run-out forecasting, inventory economics, CSV history import, progress photos, completion summaries and a larger set of free public calculators. Monthly pricing is the same; Regimen's annual plan is currently lower.
