Titer tracks every compound, dose, injection site, and vial across your entire protocol — so you always know exactly what to inject, where, and how much.
Built for people running peptides, TRT, and HCG who are done managing complex stacks from memory.
Free plan available. No credit card required.
"Did I already inject today, or was that yesterday?"
"Which site did I use last? I can't remember."
"I'm running low on BPC but I don't know exactly when I'll run out."
"My spreadsheet broke again and I lost two weeks of data."
"My TRT, HCG, and AI are all on different schedules and I keep losing track."
"How many units is 250mcg at this concentration?"
These aren't just inconveniences — they're risks. Missed doses, repeated injection sites, and surprise stock-outs cost you money and compromise your results.
Three steps. Zero spreadsheets.
Add your compounds, doses, and schedules. Titer handles complex frequencies — EOD, MWF, cycling, titration, multiple daily doses.
Open the app, see today's injections. Compound, dose in exact syringe units, timing, and which body site to use. Check them off as you go.
Monitor inventory levels, log bloodwork, track symptoms. See what's working and adjust with confidence — not guesswork.
Beyond basic calculators. One integrated system for scheduling, rotation, inventory, and data.
Visual syringe with saved recipes. Forward and reverse calculations. Enter vial size and concentration, get exact units.
Daily, EOD, twice weekly, MWF, weekly, custom days, cycling (5/2), titration. Handles overlapping compounds.
12-site body map with usage history. See which sites need rest. Prevents lipohypertrophy from repeated injections.
Track every vial — reconstituted volume, doses remaining, expiration dates. Know your stock-out date in advance.
12 health metrics plus lab panel tracking with trend charts. Upload results via AI or paste from your portal.
Group peptides, TRT, HCG, and ancillaries into unified stacks. Each compound keeps its own schedule, dose, and site.

Protocol management guides from people who actually run complex stacks.
Schedule conflicts, inventory calculations, and success metrics — mapped out before you start.
EOD, 5/2 cycling, MWF, titration phases. Why every generic reminder app breaks at 3+ compounds.
30-50% of frequent injectors develop lipohypertrophy. The 8-site pattern and how to track it.
Titer was born from frustration with managing a 7-compound stack using spreadsheets and memory. We dogfood it daily and ship based on what real users actually need.
