Tools index
Every research peptide calculator, in one place
Eight interactive tools for laboratory peptide investigators. Inputs and assumptions are documented on each tool page so any researcher can audit the formula.
Advanced Dosage Calculator
Bodyweight-scaled or absolute dosing with concentration and syringe-unit output.
Pen & Cartridge Calculator
Dial-click counts for pre-mixed Retatrutide, Tirzepatide, NAD+, GHK-Cu and combo pens.
Reconstitution Calculator
mg vial + mL BAC water → mcg/mL + U-100 / U-50 ticks.
Peptide Stack Builder
Multi-select peptides, see pairwise interactions and a weekly schedule.
Interaction Checker
Pairwise compatibility matrix across 15+ research peptides with severity tags.
Protocol Simulator
Generate a 4 / 8 / 12-week timeline with taper phases and review checkpoints.
Metabolic Estimator
Mifflin-St Jeor BMR + TDEE + projected fat-loss curves for GLP-1 class peptides.
Half-Life & Interval Calculator
Steady-state concentration curve and recommended dosing interval per peptide.
Peptide Chemistry Calculator
Sequence → MW, pI, net charge vs pH, Hopp & Woods hydrophilicity profile.
Titration Schedule Builder
Stepwise dose escalation with STEP / SURMOUNT / TRIUMPH presets and bloodwork checkpoints.
Cost & Supply Planner
Total spend, vials needed, cost per dose and bulk-vs-single-vial comparison.
