Live PK modeling
Watch a compound rise, peak, and clear in your blood — a real half-life engine, personalized to you.
NextDose models your live blood levels from real pharmacology, reads your labs from a photo, and answers with Mia — an AI grounded in your data and peer-reviewed research. Built for the compounds you actually run.
modeling live A real half-life engine draws your level between doses — rising, peaking, clearing. No other tracker can.
Take it 30–60 min before training. Pre-workout dosing supports tissue-repair signaling during mechanical load, and your SubQ dose peaks in ~45 min.
An AI grounded in your data and peer-reviewed research — with real citations, or an honest “not sure.”
18 markers extracted. LDL above range — recheck in 8 weeks. Hormones optimal for your protocol.
Snap a panel. Mia reads every marker, tracks the trend, and estimates your next draw.
Tap, speak, or scan a vial. The AI structures the log in seconds — no forms, no friction.
Your stack is checked for interactions, timing, and dosing — and your blood level is modeled live.
Grounded, cited answers about your compounds, your labs, and what to watch next.
Mia is grounded in your own data and peer-reviewed research — never forums, never guesses. It scores your protocol, flags what looks off, and shows the science behind every answer.

TRT, peptides, GLP-1 titration, a full competitive stack — if you run a protocol, it was built for you.
Watch a compound rise, peak, and clear in your blood — a real half-life engine, personalized to you.
Snap a lab panel. Mia reads every marker, tracks the trend, and estimates your next draw.
Point your camera at a vial. Concentration, volume, and expiry filled in — no typing.
Calibrate once, remembered forever. Change the dose, the draw line moves in real time.
A body map that remembers every site, so you rotate without thinking about it.
A clearance-aware taper built from your real cycle and ester half-lives — not a forum post.
Enter the vial, get exact concentrations and mixing steps. Never do the math at 5am again.
Resting HR, HRV, and sleep — correlated against your protocol, automatically.
No copy-paste from wikis. Every profile is built from peer-reviewed literature — mechanisms, dosing ranges, half-lives, PK parameters, regulatory status, and citations.

BPC-157, GHK-Cu, semaglutide — with AI that understands reconstitution, timing, and stacking.
Follow your titration, log the week, and watch the trend line build against your dosing.
Model complex stacks. The protocol audit catches interactions a spreadsheet never will.
NAD+, GH peptides, and supplements — every profile built from published science, not bro-science.
Safety briefings, visual guides, and an AI that walks your first protocol step by step.
No tiers, no upsells, no locked screens.

No. NextDose is an informational and educational tool that helps you organize and understand your protocol. It is not a medical device and does not replace your provider. Every AI answer carries a disclaimer and cites its basis.
100+ compounds across peptides, hormones, GLP-1s, SARMs, and supplements — each with half-life, dosing ranges, side effects, regulatory status, and published research. Plus bloodwork, weight, injection sites, and Apple Health.
Mia is grounded in your own data and peer-reviewed research. It gives you context, flags concerns, cites sources, and tells you honestly when it is not sure — instead of guessing.
No. NextDose does not sell, prescribe, or help you obtain anything. It is a tracking and journaling tool for whatever protocol you already run.
They use established pharmacology models with peer-reviewed parameters for each compound, personalized to your profile. It is an estimation tool, not a lab test — but a far better picture than guessing between doses.
Your data is encrypted in transit and at rest. Apple Health data is handled under Apple’s strict privacy requirements and is never used for advertising.
