How Syntho builds your protocol
A four-step process that takes your health data and transforms it into an evidence-based, personalized peptide protocol.
The Health Assessment
A 10-minute questionnaire that captures what a specialized longevity specialist would ask in a health assessment. Every question has a specific purpose.
Health conditions
To screen contraindications and ensure no peptide recommendation conflicts with existing diagnoses.
Medications
To run drug interaction checks and adjust recommendations based on concurrent therapies.
Symptoms
To target specific peptides that address your current health complaints and deficiencies.
Lifestyle
To calibrate doses based on activity level, sleep patterns, stress, and daily routine.
Goals
To select the right peptide categories: recovery, cognitive, longevity, body composition, or immune.
Experience level
To set complexity tiers and safety margins appropriate for beginners through advanced users.
The Rules Engine
A deterministic 8-step pipeline that evaluates your health profile with scientific rigor. No randomness, no shortcuts. The same input always produces the same output.
Contraindication screening
Health conditions and medications are cross-referenced against every peptide in the catalog.
Biomarker analysis
Blood test results are parsed and compared to optimal reference ranges.
Peptide selection
Eligible peptides are matched to your goals, symptoms, and health profile.
Dose calculation
Doses are calibrated to your biomarkers, body composition, and experience level.
Stacking evaluation
Peptide combinations are checked for synergies and conflicts.
Cycling schedules
On-cycle duration, off-cycle windows, and micro-cycling patterns are designed.
Monitoring plans
Blood test schedules and subjective tracking checkpoints are generated.
Missing biomarker recommendations
If key labs are missing, you're told exactly which tests to take and why.
The engine makes the protocol decisions. The AI writes the report. Every recommendation is deterministic, grounded in rules, not probabilistic guesses.
The Protocol Report
A comprehensive document that tells you exactly what to take, when to take it, how to prepare it, and what to monitor. Nothing is left to guesswork.
Peptides at a glance
A summary table of every peptide in your protocol with doses, frequency, and category.
Personalized reasoning
Why each peptide was selected for you specifically, linked to your goals and health data.
Daily injection schedule
Exact timing, injection sites, and sequencing for each day of the week.
Titration plan
Ramp-up phase, full-dose phase, and taper, structured to minimize side effects.
Reconstitution guide
Step-by-step mixing instructions, bacteriostatic water volumes, and syringe calculations.
Storage instructions
Temperature requirements, shelf life, and handling best practices for each peptide.
Blood test schedule
When to test, which markers to request, and what to look for in results.
Post-protocol planning
Off-cycle guidance, recommended products, and what your next cycle should look like.
Cycle 2 and beyond
Your protocol gets smarter with every cycle. After each round, a follow-up assessment captures what happened, and the engine adapts.
Follow-up assessment captures
- -Compliance: what you actually took vs. the plan
- -Side effects: severity, duration, and management
- -Subjective improvements: sleep, energy, recovery, cognition
- -Goal evolution: what you want to optimize next
- -Off-cycle experience: how you felt without peptides
The engine adapts
- -Dose escalation for well-tolerated peptides
- -New peptide additions based on evolved goals
- -Removal of peptides that didn't deliver results
- -Refined cycling based on your response patterns
- -Updated monitoring tailored to your trajectory
Your protocol gets smarter with every cycle, because the engine learns from your data, not from generic assumptions.
