See how it compares with Peptide Library for multi-peptide research, tracking, inventory and pricing." updated: 2026-10-25 publisher: Peptide Library notice: "Research and educational use only. Not medical advice." --- # Peptide Library vs Shotsy: GLP-1 Medication Tracker or Peptide Research Platform? Two apps with different jobs. This comparison shows where each one fits, and when Shotsy is the better pick. ## Quick verdict Shotsy isn't a peptide research app and doesn't try to be. It's a GLP-1 medication tracker for weekly injections and daily pills, with estimated medication levels, side effects, nutrition and PDF reports for care-team visits, and most of it is free. If you take a GLP-1 medication and want to stay on schedule, Shotsy is built for exactly that. Peptide Library is for people researching and organising several peptides: cited profiles, vendor price comparison, inventory and tracking. ### Choose Peptide Library if - You research or track peptides beyond GLP-1 medications. - You manage vials, capsules or sprays and want stock levels, run-out and reorder dates. - You compare vendors for research compounds by listing and price per mg. - You want cited research profiles and a web app. ### Choose Shotsy if - You take a prescribed GLP-1 medication, as an injection or a pill, and want a dedicated tracker. - You want estimated medication-level charts for the GLP-1 medicines it supports. - You want PDF reports to bring to appointments. - You want free nutrition and side-effect tracking alongside your doses. ## Key differences ### One drug class, or many peptides Shotsy supports GLP-1 receptor agonists for weight management and type 2 diabetes. Peptide Library covers 200+ peptide profiles and lets you track any compound, including GLP-1s. ### Inventory Shotsy's listing and site don't mention vials or stock. Peptide Library tracks vials, capsules, nasal sprays and ready-to-use containers, deducts stock as you log and forecasts when to reorder. ### Clinical charts or research references Shotsy's medication-level charts draw on published clinical data for four GLP-1 medicines. Peptide Library cites studies on each profile and publishes research statistics, but doesn't chart levels. ### Care team or research workflow Shotsy produces PDF reports for appointments. Peptide Library is organised around research: profiles, comparisons, trends and vendor information next to your log. ## Research Shotsy focuses on the medicines it supports: its estimated medication-level charts are based on peer-reviewed clinical data for semaglutide, tirzepatide, liraglutide and dulaglutide. It does not advertise a compound library or research references. Peptide Library's 200+ profiles cover a much wider range of peptides, each with cited sources and evidence labels. The Research Intelligence Center publishes publication and clinical-trial statistics, and Peptide Trends shows what the community researches. ## Tracking Shotsy logs an injection or a pill with a single tap, supports several medications with separate schedules, counts down to the next dose and plans titration. Its rotation map suggests the next injection site, and side effects can be linked to doses, sites, nutrition or hydration. Peptide Library logs any compound, with schedules for every day, chosen weekdays, every N days, on/off cycles, several times a day and titration. The apps rotate injection sites on a body map, and each dose can draw stock from inventory. ## Vendors Shotsy is a medication tracker and doesn't advertise vendor features, which suits prescribed medicines filled by a pharmacy. Peptide Library's vendor tools serve people comparing research-compound listings: offers by compound and form, price per mg and vendor reviews. ## Pricing Shotsy's website says its core features are free, including dose and side-effect tracking, weight charts and nutrition logging; the App Store lists premium plans from $9.99 to $14.99 a month and $39.99 to $59.99 a year. Peptide Library's free plan includes tracking, and Pro is $4.99 a month, $39.99 a year or $89.99 once. ## Where Shotsy is stronger ### Purpose-built for GLP-1 medications Injections and daily pills, with pill tracking on iPhone, and schedules built around weekly doses. ### Medication-level estimates Charts based on published clinical data for the GLP-1 medicines it supports. ### Reports for your care team PDF reports designed for appointments. ### A generous free tier Dose and side-effect tracking, weight charts and nutrition logging are free. ## Features | Feature | Peptide Library | Shotsy | |---|---|---| | iPhone app | Yes | Yes | | Android app | Yes | Yes | | Web app | Yes, installable | Not advertised | | Free plan | Yes (inventory: 1 peptide) | Core features free | | Dose logging | Yes | Yes | | History and calendar | Yes | Yes | | Recurring schedules | Yes | Yes | | Reminders | Yes | Yes | | Cycles and titration | Yes | Titration schedules | | Vial inventory | Yes (free: 1 peptide) | Not advertised | | Low-stock or run-out alerts | Yes | Not advertised | | Expiry dates | Yes | Not advertised | | Stock deducted on logging | Yes | Not advertised | | Compound library | 200+ profiles | Not advertised | | Cited research references | Yes | Not advertised | | Publication and trial data | Yes | Not advertised | | Community research trends | Yes (full view with Pro) | Not advertised | | Vendor directory | Yes | Not advertised | | Vendor price comparison | Yes | Not advertised | | Price per mg | Yes | Not advertised | | Vendor reviews | Yes | Not advertised | | Reconstitution calculator | Android and web | Not advertised | | Estimated level charts | No | For GLP-1 medications | | Weight and body metrics | Yes | Yes | | Progress photos | Yes (free: up to 2) | Not advertised | | Journal or symptom check-ins | Yes | Side-effect tracking | | Injection-site rotation | In the apps, not on the web | Yes | | Nutrition tracking | No | Yes | | Community | Discussions free; Q&A with Pro | Not advertised | | Apple Health | Yes | Yes | | Health Connect (Android) | Yes | Not advertised | | Wearables | No | Not advertised | | Home Screen widgets | iPhone only | Yes | | AI assistant | No | Not advertised | | Multi-device sync | Pro (free Android accounts sync most data) | Yes | | On-device storage | Yes | On iPhone, with iCloud sync | | Data export | Pro | PDF reports for care teams | ## Final verdict If your focus is a prescribed GLP-1, Shotsy is the more specialised tool and most of it is free. Peptide Library doesn't try to replace that; it's for people who research and organise several peptides and want inventory and vendor information in the same place. Many readers will only need one of the two. If you need both, they cover different ground. ## Frequently asked questions ### Is Shotsy a peptide tracker? Shotsy is a GLP-1 medication tracker. It covers semaglutide, tirzepatide, liraglutide and dulaglutide as injections and pills, rather than research peptides in general. ### Is Shotsy free? Its website says the core features are free. The App Store also lists premium plans from $9.99 to $14.99 a month and $39.99 to $59.99 a year (US, checked October 2026). ### Does Shotsy track vials or inventory? Its listing and website don't mention inventory. Peptide Library tracks vials, capsules, nasal sprays and ready-to-use containers and deducts stock as you log. ### Is Shotsy on Android? Yes, Shotsy is on Google Play; its website says pill tracking is iPhone-only. Neither app store listing mentions a web app, while Peptide Library also runs in a browser. ### Where does Shotsy store my data? On iPhone, on the device with private iCloud sync. Its website says Android data is stored in Google Firebase. Peptide Library's apps keep data on the device with optional account sync. ### Can Peptide Library track a GLP-1? Yes. You can log any compound with schedules, reminders and inventory. It does not chart estimated medication levels the way Shotsy does. Comparisons use public listings and websites. "Not advertised" means no source we checked mentions the feature, not that it is missing.
