No account is needed to log injections, set daily or weekly reminders, and view your history and Insights. Create a free account with Apple or Google to sync across your devices and to unlock advanced scheduling — cycles, titration (warm-up), and custom interval reminders.

Whether you're managing peptides, prescriptions, or personal health therapies, Injectly helps you log every injection, stay on schedule, and understand exactly what's happening between each dose. Enjoy! For supported medications, the Insights tab turns your logbook into a live serum concentration dashboard. Injectly automatically pulls in the applicable medication you've been using, calculates current and projected levels based on your logged dose history and weight, and shows how close you are to peak along with how much of the dose remains active. Features: • Log each injection with dose, medication, date, time, route (SubQ/IM/IV), and injection site so you always have a searchable history — and can rotate sites. • Save and reuse custom protocols for peptides, prescriptions, or personal therapies in a couple of taps. • Reminders that match your cadence — daily, weekly, or specific weekdays — with multiple reminders per protocol and the dose amount shown right in the notification. • Cycles: run on/off schedules (weeks on, weeks off) with reminders that follow the cycle automatically. (free account) • Titration / warm-up: ramp a dose up or down over time, with a reminder for each step.

Your testosterone protocol doesn't run itself. Himcules does. TRT works when you're consistent. Himcules is the testosterone injection tracker built for men who treat their TRT protocol the way serious people treat anything that matters — precisely, without gaps. Whether you're working with a longevity clinic, a urologist, or running your own protocol — this TRT tracker adapts to how you train, not the other way around. — THE WORK — • Never miss a TRT dose. Three injection reminders per shot — day-before, hour-before, on-day — each one a nudge before missing becomes an option. • Never run dry. Vial supply tracked automatically. You're warned before you run short, not after you've already missed an injection. • Rotate correctly. 14 injection sites — 6 IM, 8 SubQ. Himcules sequences your rotation, prevents hot spots, and marks every site you've hit. • Any testosterone protocol. IM, SubQ, mixed. Weekly, MWF, twice-weekly, or custom. Enter your split once. We handle every schedule from there. — THE PICTURE — • Know your testosterone levels — without a lab. Cypionate, enanthate, propionate: pharmacokinetic curves modelled per ester, visualized over time. The most granular T-level prediction in any iOS TRT tracker. • Track the full wellness picture. Energy. Mood. Libido. Sleep. Check in after each injection. Watch the correlation between consistency and how you feel emerge over weeks. • See your adherence. 95%+ means your protocol is running clean. Below 90% and you'll see that too. No flattering dashboards. — THE PROOF — • Log in one tap from your home screen. Native iOS widget — lock screen and home screen. Glance, tap, logged. No unlocking required. • Bring it to your provider. Doctor-ready PDF export in one tap. Show your injections, your sites, your TRT adherence — in a format your clinic recognises. • Your data is yours. Stored on-device, backed up to iCloud. We never see it. We never sell it. That's the entire policy. — BUILT DIFFERENT — Most TRT trackers are web forms wrapped in a mobile shell. Himcules is built native iOS — widgets, iCloud sync, pharmacokinetic modelling, full wellness logging — and lives in the Medical category for a reason. Free to download. Core injection tracking has no paywall. Premium tier coming: advanced PK analytics, deeper wellness trends, cross-platform cloud backup. — QUESTIONS — Running your own testosterone protocol without a doctor? Set your dose, frequency, and schedule manually. Himcules doesn't require a prescription. On compounded T? Cypionate, enanthate, propionate, sustanon — all supported by name. SubQ or IM? Both. Mixed TRT protocols too. Subscription required? Not for core tracking. Bro Mode? Optional. Off by default. Download. Set your protocol. Log tonight.
