Tools
Free UK tools built from the SmPCs and our register data. The maths is shown, the sources are cited, and nothing here recommends a medicine.
Peptide calculator
Four tools in one: the maths for a dose you’ve been prescribed.
Reconstitution calculator
Reconstituting (mixing) a new vial? Enter the powder’s mg, your BAC water, and your dose → the exact units to pull on an insulin syringe, plus doses per vial.
mg ↔ units converter
Already mixed and know the strength? Convert mg to units and units back to mg, and see how far to fill the syringe.
How much BAC water?
How much BAC water (bacteriostatic water) to add so your dose lands at an easy-to-draw number of units.
Blend / stack calculator
A blended or stacked vial with several peptides: set the dose on one and see how much of each of the others is in every draw.
