Live interactive calculators — not static charts. Reconstitution, dose planning, TDEE, lab range interpretation, half-life, protein target. Free to use, no email gate, no login. The math is the math.
How much protein you actually need each day.
Daily protein in grams with per-meal split and leucine-threshold math. Built for GLP-1 cuts, recomp, hypertrophy, and age-related anabolic resistance.
Exactly how much creatine to take — and for how long.
Loading and maintenance grams by bodyweight, teaspoon equivalents, and the days to fully saturate your muscle stores. Monohydrate, dosed by the actual research.
mg, mcg, IU, kg, °C — the dose units that trip people up.
mg ↔ mcg ↔ g, kg ↔ lb, mL ↔ tsp, °C ↔ °F — plus a substance-correct IU ↔ mcg converter for vitamin D, A, and E. No fake universal "IU to mg."
Calories into protein, carbs, and fat — done right.
Protein anchored to bodyweight, fat set for hormones, carbs filling the rest. By goal and diet style (balanced, low-carb, keto), with a per-meal split. The companion to TDEE.
Your real daily calorie burn — and how to split it.
Honest energy math (Mifflin-St Jeor + activity), protein floor for lean-mass preservation, deficit guidance for GLP-1 cycles.
What your bloodwork numbers actually mean.
Paste a lab panel; get plain-English range interpretation, cross-references to the relevant drug or topic page, and flags worth asking your clinician about.
Your last coffee that won't wreck sleep.
Half-life math by CYP1A2 metabolizer phenotype. Work backwards from your bedtime to the latest dose that won't measurably touch your sleep architecture.
Two peptides, one vial, one clean injection.
Mix two or more peptides in one vial — CJC + Ipamorelin, BPC-157 + TB-500, GHK-Cu stacks. Per-compound dose-per-tick math on a U-100 insulin syringe. One vial, one injection, one calculation.
Exactly how many units to draw.
Vial mg + bacteriostatic water → the exact unit mark to draw on a U-100 syringe, shown on an animated syringe. Presets for semaglutide, tirzepatide, BPC-157, CJC.
Turn your A1C into an everyday glucose number.
Convert A1C to estimated average glucose (eAG) in mg/dL and mmol/L — and back. Plain-English normal / prediabetes / diabetes context for the metabolic crowd.
Map your full dosing schedule and cost.
Build a full titration + maintenance schedule — weekly doses, cumulative mg, vials needed, and projected cost — for GLP-1s and peptides.
How long a compound stays in your system.
Steady-state and washout time from a compound's half-life — see accumulation and how long it takes to clear after you stop.
