NextDose models your levels in real time, reads your bloodwork with AI, and tracks every dose — and gets more accurate the longer you use it.
No data-entry marathon. Add your compounds, set your protocol, log your first dose — and watch your levels come alive.
Pick from 100+ peer-reviewed profiles — Test C, BPC-157, Tirzepatide, Tadalafil — or scan a vial with your camera.
Frequency, dose, route — pre-loaded with the published range. Tune it to your goals or accept the standard.
Voice, tap, or scan. Your blood level updates on the live PK curve the second you log a dose.
Real-time PK modeling, AI bloodwork analysis, vial scanning, and a Mia that learns your body.
A real half-life engine. Bateman pharmacokinetics, calibrated by your bloodwork. Every dose redraws the curve.
AI extracts every marker — TT, FT, E2, hematocrit — plots the trend, predicts your next.
Camera reads the compound, concentration, brand & lot in seconds.
Long-press to preview your syringe fill — the answer appears before the sheet opens.
Tiered warnings on every log. Published-range checks. Interaction flags.
Real screens from the app — blood-level modeling, compound research, bloodwork, dosing, and Mia.
It starts with published pharmacology — then quietly re-anchors to you: calibrated to your panels, adjusted for your body composition, refined by your wearable. It gets sharper the longer you use it.
Published half-life and dosing for every compound.
Re-anchored to your own bloodwork panels.
Adjusted for your weight and composition.
Refined by Apple Health signals over time.

Every protocol that runs through NextDose makes the intelligence behind it a little sharper — for everyone.
No copy-paste from forums. Every profile — peptides, TRT, GLP-1s, SARMs, prescriptions, vitamins — is built from published peer-reviewed literature, with half-life, dosing range, side effects, and citations.
TRT patients, peptide researchers, GLP-1 users, coaches — one place for the whole protocol instead of three apps and a notes file.
Early-tester feedback, shown for illustration. Individual experiences vary. Real App Store reviews replace these at launch.
No locked screens, no add-ons. PK modeling, bloodwork AI, Mia, and the full library — all included.
Subscriptions are billed through your Apple ID and renew automatically. Cancel anytime in your Apple ID settings.
No. NextDose is a personal tracking and organization tool — a journal for protocols you've decided on with your healthcare provider. It does not prescribe, recommend, or calculate medical dosages. Every AI answer is observational, cites published research, and points you back to your provider.
100+ across 6 categories — peptides, TRT and anabolics, GLP-1s, SARMs, growth hormone, and support/ancillaries. Every profile is built from published, peer-reviewed literature, with half-life, dosing range, side effects, regulatory status, and citations.
Yes. A real pharmacokinetic engine draws a live blood-level curve for each compound, then re-anchors it to your own bloodwork and body composition. When there isn't enough data yet, it's clearly labeled ESTIMATED and tightens as you log more.
Yes. Log a dose anywhere, even with no signal — it saves instantly and syncs the moment you reconnect. A logged dose is never lost.
Your data is encrypted and never sold. Your name, photos, and identity are never sent to the AI. You can export or delete everything at any time. NextDose is not a HIPAA-covered entity — your inputs are not protected health information — and we say so plainly.
One plan, every feature: $16.99/month, or $119.99/year with a 7-day free trial. Billed through your Apple ID; cancel anytime in your Apple ID settings.
