Reminders are timed to each compound's half-life — not arbitrary schedules. Your Test E reminder is set for every 3.5 days based on its 4.5-day half-life to maintain stable serum levels. BPC-157 reminders are split AM/PM because its SubQ half-life is ~4 hours. Semaglutide is weekly because its t½ is 7 days. All timing is adjustable.

First-Timers

Intelligence Layer

An AI that knows your compounds.

NextDose.AI is your research companion — grounded in published research, aware of your stack, and always honest about what it doesn't know.

Real-time safety checks
Every dose you log is automatically checked against published research. If something looks off, the app lets you know — so you can double-check before logging. It's an extra layer of awareness built into your workflow, not a replacement for professional guidance.
Protocol scoring
Your entire stack is scored 0-100 across four dimensions: safety (interactions, contraindications), dosing (within published ranges), timing (half-life optimized scheduling), and support (ancillaries, liver protection, PCT readiness). The score updates live as you modify your protocol.
Source-cited intelligence
The AI is grounded in published, peer-reviewed research — not internet forums or unverified claims. When it gives you information, it's backed by real science. When it doesn't have a confident answer, it tells you honestly instead of guessing.
Community-informed insights
The AI learns from anonymized, de-identified patterns across the NextDose.AI community — helping it understand real-world usage trends over time. No personal data is ever exposed. Your individual protocol data stays private and is never shared with other users.
Built-in safety layer
Every AI output passes through a proprietary safety enforcement layer before reaching you. The system is designed to reference published research ranges, flag potential concerns, and always include appropriate disclaimers. It supplements — never replaces — guidance from your healthcare provider.
Predictive bloodwork modeling
After two or more blood panels, the AI begins predicting where your markers are heading based on your protocol, dose history, and historical trends. Predicted values are shown with confidence ranges so you know what to expect before your next draw.
Pharmacokinetic engine
Real-time blood level estimation using established pharmacology models with peer-reviewed data for every compound in the library. The engine personalizes curves based on your profile to give you the most accurate picture of what's happening between doses.
MiaOnline
Your protocol AI · grounded in your data
Should I take my BPC-157 before or after my workout?
MIA · GROUNDED ANSWER
Based on your protocol, take BPC-157 30–60 min before training. Pre-workout dosing enhances tissue repair signaling during mechanical stress. Your SubQ injection reaches peak bioavailability in ~45 min.
📚 3 citations👥 1,247 users with this stack
Can I stack it with my Test C injection?
Yes — no known interactions between BPC-157 and Test C. Different routes (SubQ vs IM), different mechanisms. Same-day administration is fine.

FAQ

Questions? We got you.

Is this medical advice?

No. NextDose.AI is a personal health journaling and informational tool. It helps you organize and understand your protocol, but it's not a medical device and doesn't replace your doctor. The AI includes safety disclaimers and is designed to inform, not prescribe. Always consult your healthcare provider before making health decisions.

What can I track?

77+ compounds across peptides, hormones, GLP-1s, supplements, and more. Each compound has a detailed profile — half-life, dosing info, side effects, regulatory status, and published research. You can also track bloodwork, weight, injection sites, and sync with Apple Health.

Is my data private?

Your data is encrypted and protected by industry-standard security. Apple Health data is handled per Apple's strict privacy requirements and is not used for advertising. For full details on how we handle your information, read our Privacy Policy.

How much does it cost?

$16.99/month or $119.99/year. One plan — every feature included, no locked screens. The annual plan includes a 7-day free trial. Cancel anytime through your Apple ID settings.

How smart is the AI?

The AI is grounded in published, peer-reviewed research. It gives you context about your compounds, flags potential concerns, and helps you understand your protocol better. It includes safety guardrails and always tells you when it's not sure about something instead of guessing.

Do I need a prescription?

No. NextDose.AI doesn't sell, prescribe, or help you buy anything. It's a tracking and journaling tool for whatever protocol you're already on — TRT, peptides, GLP-1s, supplements, or anything else. Think of it as a smart notebook, not a pharmacy.

How does bloodwork tracking work?

Snap a photo of your lab results and the app reads the values automatically. You can also enter them manually. It tracks your markers over time so you can see how things are trending. After a couple panels, the AI can even give you a heads up on where your markers might be heading.

Is there a free trial?

Yes — the annual plan includes a 7-day free trial with full access to every feature. After the trial, your subscription begins automatically unless you cancel through your Apple ID settings. The monthly plan starts billing immediately (no trial).

What about Android?

iOS only right now. We built it natively to get the most out of Apple's platform. Android is something we're thinking about but nothing to announce yet.

How accurate are the PK curves?

They're based on established pharmacology models using peer-reviewed data for each compound. The app also personalizes the curves based on your profile. It's an estimation tool — not a lab test — but it gives you a much better picture of what's happening between doses than guessing.
