Dose calculator
Standard research pen format: 3 mL total volume, 300 clicks per pen. That’s fixed — so the only thing that changes is how many mg are in your specific pen. mg per click = your pen’s mg ÷ 300.
Vial mode: most research peptide vials are 3 mL borosilicate glass (industry standard — about 99% of compounds ship in this size). Larger compounds like NAD+ or high-mg GHK-Cu sometimes come in 5–10 mL vials. The bacteriostatic water you add must fit inside your physical vial — for a standard 3 mL vial, that’s usually 1–3 mL of BAC water. Tell us the vial’s peptide content (in mg), the BAC water you added, and your target dose — we work out the concentration, the volume to draw, and the syringe units on a U-100 insulin syringe.

How nootropic dosing differs from peptide dosing
Most nootropics are oral (capsule or powder) rather than injected, so the calculator handles them differently from peptides. For Adrafinil, you’re working in milligrams of capsule contents per dose, not click counts on a pen. The calculator above adapts automatically based on which compound you select.
For nasal peptide nootropics like Selank and Semax, the calculator works in microlitres of nasal spray with a concentration set by the reconstitution step — same maths as injectable peptides, delivered through the nose instead of a syringe.
