Peptide Cycle Calculator

Calculate exactly how much total product you need before starting a research cycle. Enter your dose, frequency, and cycle length — the calculator returns total vials required and total cost across your preferred vendors.

How to use the cycle calculator

Select your compound, enter your dose per injection in mcg, your injection frequency, and your cycle length in weeks. The calculator shows total product needed and helps you compare cost across vendors currently listed on RUO Codes.

Why plan your supply before starting

Running out of a compound mid-cycle is one of the most common and avoidable research mistakes. Calculating total supply needed upfront lets you buy everything at once — often at a lower cost per unit when buying in bulk — and avoids gaps caused by shipping delays or restocks.
