Tools for optimization
Science is useful.
Data is powerful.
A focused set of calculators that turn research into action. Every tool runs entirely in your browser — no sign-up, nothing stored, nothing sent anywhere.
Peptides
Peptide Reconstitution Calculator
Turn vial strength, bacteriostatic water, and target dose into exact insulin-syringe units — with concentration and doses per vial.
Open tool →Peptide Blend / Stack Calculator
Reconstitution math for multi-peptide blends — BPC+TB-500, CJC+Ipamorelin, GLOW — with the exact micrograms of every component per draw.
Open tool →Peptide Dose & Unit Converter
Convert mcg ↔ mg, mL ↔ insulin units, and IU ↔ mg in one place — with a concentration-aware mcg-per-unit readout.
Open tool →Vial Duration Estimator
See how many doses a vial holds and how long it lasts from strength, dose, and frequency — plus a run-out date so you reorder in time.
Open tool →Peptide Half-Life Visualizer
Watch a single dose clear over time from its half-life, with the point it reaches half, a quarter, and a trace — and approximate presets.
Open tool →Dose Interval Visualizer
See whether repeated doses build up to a plateau from a half-life and interval — the accumulation ratio and how long steady state takes.
Open tool →Peptide Research Glossary
Plain-language definitions for the peptides, mechanisms, and acronyms you keep running into — with honest evidence labels.
Open tool →GLP-1 & metabolic
GLP-1 Weight-Loss Projector
See the average weight-loss trajectory from the pivotal trials for your starting weight and medication — the trend, not a promise.
Open tool →GLP-1 Titration Schedule
See the label step-up schedule for Wegovy, Ozempic, Zepbound, or Mounjaro mapped to your own calendar — your current step, and when the next one lands.
Open tool →Electrolyte & Hydration Calculator
Daily fluid, sodium, potassium, and magnesium targets tuned for GLP-1 use, extended fasting, or keto — the losses those states actually cause.
Open tool →Protein Intake Calculator
Find a daily protein target that protects muscle while you lose fat — with a per-meal split you can actually hit.
Open tool →Lean-Mass Preservation Planner
Estimate how much of your weight loss is coming from muscle — and how a slower pace, more protein, and lifting change the split.
Open tool →TDEE & Macro Calculator
Estimate maintenance calories with Mifflin-St Jeor, then get protein, fat, and carb targets tuned to your goal.
Open tool →HOMA-IR Calculator
Estimate insulin resistance and beta-cell output from fasting glucose and insulin — two numbers your basic panel already holds.
Open tool →A1c ↔ Glucose Converter
Turn an HbA1c into an estimated average glucose and back, in mg/dL and mmol/L, with the ADA category context.
Open tool →Waist-to-Height Ratio
One of the simplest useful metabolic-risk screens — often better than BMI. Keep your waist under half your height.
Open tool →Fiber Intake Calculator
A daily fiber target from your calories and age — and the gap to what you eat now. The highest-leverage neglected lever on a GLP-1.
Open tool →Weight-Loss Rate Calculator
Project how long your goal takes at a chosen weekly rate — and whether that pace protects lean mass or burns it.
Open tool →GLP-1 Progress Tracker
Track weight, metabolic markers, and treatment response over time — and see the trends that matter, not the daily noise.
Join the waitlist →Longevity & performance
Biological Age Calculator
Estimate your phenotypic age from nine standard blood markers using the peer-reviewed Levine PhenoAge algorithm.
Open tool →VO2 Max Calculator
Estimate one of the strongest predictors of longevity from a resting heart rate or a 12-minute run — with a fitness rating.
Open tool →One-Rep Max Calculator
Estimate your 1RM from any set and get a full training-load table from 50% to 95% to program every session.
Open tool →Training Volume Calculator
Check your weekly sets per muscle against evidence-based landmarks — what is below the growth minimum, productive, or past your recoverable ceiling.
Open tool →Body-Fat % Calculator
Estimate body-fat percentage with the U.S. Navy tape method, plus a lean-vs-fat mass breakdown and a category rating.
Open tool →FFMI & Lean Body Mass
Gauge how much muscle you carry for your height — the number that tells you whether you are preserving lean mass, not just losing weight.
Open tool →Creatine Dosing Calculator
Weight-based loading and maintenance doses for creatine monohydrate — with the saturation-timeline tradeoff of skipping the load.
Open tool →ASCVD 10-Year Risk
Estimate your 10-year cardiovascular risk with the ACC/AHA Pooled Cohort Equations — the number that anchors a statin conversation.
Open tool →Blood Pressure Category
Map a reading to the ACC/AHA 2017 categories — normal through crisis — and see which number is driving it.
Open tool →ApoB Context Tool
Interpret an ApoB result against commonly-cited thresholds — the atherogenic particle count that can diverge from your LDL-C.
Open tool →Recovery & sleep
Caffeine & Sleep Cutoff
See how much caffeine is still circulating at bedtime — and the latest your last cup should be for undisturbed sleep.
Open tool →Sleep Cycle Calculator
Find a bedtime or wake time aligned to 90-minute cycles, so you wake between cycles instead of mid-cycle.
Open tool →Alcohol Metabolism / Sober-By
Estimate peak blood-alcohol and when it clears using the Widmark method — an educational timeline, never a fitness-to-drive test.
Open tool →Intermittent Fasting Timer
Track your fasting window with a live timer and honest metabolic milestones — 16:8 through 36-hour fasts.
Open tool →Recovery Readiness Questionnaire
Rate sleep, soreness, energy, mood, and stress for a daily readiness score — and a clear call to push, train, scale back, or rest.
