An assistant that knows your protocol
Grounded in the library and your own logs, and honest when it doesn't know.
AI assistant that knows your protocol
Ask about mechanisms, side effects, storage, or how two peptides stack. Peppy reads your regimen, logs, and the library, then answers in plain English — and cites the source. Hit a symptom and it points you toward urgent care.
- "Should I take BPC-157 with food?"
- "How much BAC water for 5 mg?"
- "What if I missed yesterday's dose?"
- "Is this stack safe with my logs?"
Bloodwork analysis, not just numbers
Upload your latest panel and Peptide Streak compares each marker to your previous results, explains what the trends mean, and gives you the right questions to ask your clinician before your next visit.
- Side-by-side panel comparisons
