The current reality
You've spent hours reading Reddit threads, piecing together contradictory advice from anonymous users who may or may not know what they're doing. You've found a peptide that sounds promising, picked a dose from a forum post, and hoped for the best. No one checked your health history. No one looked at your blood work. No one told you what to monitor or when to stop.
The Syntho approach
Syntho starts with your health data: your conditions, medications, biomarkers, and goals. A deterministic safety engine screens every recommendation before you see it. Doses are calibrated to your body. Cycling schedules are structured. Monitoring checkpoints are built in. This is what protocol design looks like when it's built from evidence-based methodology, not crowdsourced guesswork.
Process
How it works
From health assessment to optimized protocol in four steps.
Health Assessment
A 10-minute questionnaire covering your health history, symptoms, lifestyle, goals, and bloodwork. We ask what a longevity specialist would ask.
Blood Work
Upload blood test results from any lab worldwide. Our system extracts and analyzes your biomarkers automatically.
Protocol Generation
A deterministic rules engine evaluates contraindications, matches peptides to your goals, calibrates doses to your biomarkers, and designs your cycling schedule.
Guided Execution
A complete protocol report: which peptides, at what doses, with what timing, what to track, what blood tests to take, and what your next cycle should look like.
Why Syntho
What makes this different
Rules Engine, Not a Chatbot
Our protocol recommendations come from a deterministic safety rules engine with 56 automated tests covering safety, dosing, stacking, and cycling. The AI writes the report; the engine makes the decisions.
Biomarker-Calibrated Dosing
Upload your bloodwork and your doses are calibrated to your IGF-1 levels, metabolic markers, and hormonal profile. No biomarkers? We tell you exactly which tests to take.
Full-Spectrum Coverage
GH secretagogues, healing peptides, cognitive enhancers, immune modulators, metabolic compounds, longevity peptides, and more, mapped to your specific goals.
Cycle Intelligence
Every protocol includes titration planning, micro-cycling schedules, off-cycle guidance, and next-cycle recommendations. Not just what to take: when to start, when to stop, and what comes next.
