Laboratory planning tools

Reta research tools

Three free, no-signup tools for laboratory planning: a vial reconstitution calculator, plus a pen planner and a clicks-to-mg converter for the 10mg, 20mg, 30mg and 40mg reta pen formats. Inputs are processed in the browser and outputs are immediate. If you need mechanism context before the math, start with the reta peptide guide.

Tools are for in-vitro laboratory research planning. Not medical advice.

Available tools

Vials Vial Calculator Peptide vial reconstitution: enter the vial strength (mg) and the bacteriostatic water added (mL), then a target amount in mg or units on a U-100 syringe. Pens Pen Planner Retatrutide pen planning for 10mg, 20mg, 30mg and 40mg pens: enter an amount in mg, how often and for how many weeks to see the clicks per amount and the number of pens needed. Pens Pen Clicks to mg Converts pen-click count into mg for the 10mg, 20mg, 30mg and 40mg pen formats. Shows remaining clicks and mg in the cartridge.

Working out the math on a specific pen?

The pen tools cover the 10mg, 20mg, 30mg and 40mg Reta pen formats. The published batch records behind those formats — Janoshik task IDs, HPLC purity and verification keys — sit in the COA library on this domain.
