Calculators & references
Peptide tools
Accurate, free, and sells-nothing. Built to be the clearest tools of their kind — no signup, no upsell, no fabricated reviews.
- Reconstitution & dosing calculator
Enter vial mg, BAC water, and your target dose — get the concentration, the exact mL to draw, and the insulin-syringe units, with a live syringe diagram.
- Mixing / co-administration compatibility
Can two peptides go in the same syringe? An honest compatibility matrix and a "pick two" checker — with sterility notes and a first-class "insufficient data" answer.
- Cost-per-dose calculator
Enter vial price, vial mg, dose, and how often you dose — get cost per shot, per week, per month, per cycle, and the vendor-neutral cost per mg. Sells nothing.
- Half-life & re-dose visualizer
Enter a half-life, dosing interval, and dose count — see the plasma curve build to a plateau, where peaks and troughs land, and why long-acting means smoother dosing.
