NextDose models your levels in real time, reads your bloodwork with AI, and tracks every dose — a personal protocol journal built for how people actually run compounds.
01 — The intelligence
It starts with published pharmacology, then quietly re-anchors to you — calibrated to your panels, adjusted for your composition, refined by your wearable. It gets sharper the longer you use it.
01 · Modeled
Published half-life and dosing for every compound.
02 · Calibrated
Re-anchored to your own bloodwork panels.
03 · Biometric
Adjusted for your weight and composition.
04 · Learned
Refined by Apple Health signals over time.

02 — Research-grade library
No copy-paste from forums. Every profile is built from published, peer-reviewed literature — with half-life, dosing range, side effects, regulatory status, and citations.
03 — Questions
No. NextDose is a personal tracking and organization journal — for protocols you’ve decided on with your healthcare provider. It doesn’t 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.
