Alternatives · 2026
Shotsy is a tidy GLP-1 tracker, but it isn't built for everyone. If you need reconstitution calculators, peptide support, or web access, here are the alternatives worth considering.
Peptidy is the most complete alternative if you want more than GLP-1 weight tracking. It logs injections, tracks adherence and body metrics, and includes free reconstitution calculators for 17 compounds plus an educational library with citations — all on web and iOS. It's the natural step up if you've outgrown a single-purpose GLP-1 app.

Peptidy vs PepCalc →Generic medication-reminder apps can nudge you to take your shot, but they aren't built for injections, reconstitution, or peptide protocols, so they miss most of what a dedicated tracker offers.
Free and fully in your control, but with no reminders, no calculators, and no adherence view — and it gets harder to maintain as your protocol grows.
Peptidy is the most complete alternative for people who want more than GLP-1 weight tracking. It adds reconstitution calculators, research-peptide support, adherence tracking, and web access alongside injection logging — all in one app.
Yes. Peptidy runs as a full web app as well as on iOS, so you can manage your protocol from a browser or your phone, and your data syncs between them.
Peptidy includes free reconstitution calculators for 17 compounds, including semaglutide, tirzepatide, BPC-157, and TB-500 — useful if you reconstitute your own vials rather than using pre-filled pens.
No. Injection trackers, including Peptidy, are record-keeping tools. They don't diagnose or recommend treatment. Always consult a qualified healthcare professional before making any medical decisions.
