Frequently asked questions
Yes - calculator, schedules, and dose log are free with no signup. Charts appear only after you log real doses. Data lives in your browser; sign in to sync across devices and turn on Email / SMS / iCal reminders.
Yes. Built-in ladders: semaglutide 0.25 → 2.4 mg weekly, tirzepatide 2.5 → 15 mg weekly, retatrutide 2 → 12 mg weekly, liraglutide 0.6 → 3.0 mg daily. The ladder advances on the configured step weeks.
Pick any combination of Email, SMS, and iCal per schedule. Email / SMS fire from a cron sweep at your configured offset; the iCal feed plugs into Apple or Google Calendar so your phone's native notifications handle the rest.
Only after you log real doses. It is a single-compartment exponential-decay overlay of modelled amount remaining for compounds you have already logged - never a preloaded demo. Half-lives come from FDA labels and peer-reviewed PK studies. Educational only - not medical advice .
Yes - a 12-zone body map colour-codes sites by recency: red < 7 days, amber < 30 days, green clear. Auto-suggests the next site to avoid repeat injections.
GLP-1s (semaglutide, tirzepatide, retatrutide, liraglutide), healing peptides (BPC-157, TB-500), GH secretagogues (ipamorelin, CJC-1295 ±DAC, sermorelin, tesamorelin), cosmetic (GHK-Cu), metabolic (MOTS-c, AOD-9604), longevity (epitalon). Citations at /api/tracker/catalog .
