Blend vials in the calculator
Updated Oct 16, 2026 · Applies to Web · All plans
On the web, the calculator can handle a vial that holds more than one compound. It shows each compound's share of the vial, how much of each is in one unit, and how much of each any draw contains. The Dose calculator in the message box, and the iPhone and Android apps, work with one compound at a time.
Open the blend calculator
- Calculator in the sidebar: above the calculator, choose a blend by name instead of Single peptide. Its components are filled in, with amounts where ChatPEP has them.
- On the ChatPEP website: each blend's page, under Blends in the top menu, has the same calculator.
- In an answer: when ChatPEP works out the math for a blend, the answer includes this calculator, and you can change its numbers there.
On iPhone and on Android, an answer about a blend shows a summary card with the components listed instead. For the full breakdown, open the chat on the web.
Fill it in
- For each row, check the Component name and enter the amount from the vial label under In vial (mg). On a narrow screen, these read Component and mg.
- Optionally, enter an amount of that component under Target (mcg) to see how many units contain it.
- Select Add component for another row. Select the X at the end of a row to remove it. A blend keeps at least two rows.
- Enter the water under BAC water, in ml.
- Enter the units under Draw. Until you change it, Draw follows the first component that has a target.
Some blends list their components without amounts, and those rows start at zero. Blends sold under the same name can differ, so match every amount to the label.
Read the result
The first line gives the total mg in the vial, the water, and the total units of liquid. The table then shows, for each component:
- Share: its part of the vial's total mg.
- mcg / unit: how much of it is in each unit.
- The column named for the draw, such as At 30 units: how much of it that draw contains.
- Units for target: how many units contain the target you entered, if you entered one.
Why one draw carries every component
Every component is dissolved in the same liquid, so any draw contains all of them at the vial's ratio. You cannot change one component without changing the others.
The numbers below only show the arithmetic. A vial holds 10 mg of Compound 1 and 5 mg of Compound 2, with 3 ml of water, which makes 300 units:
- Compound 1 is 10,000 mcg divided by 300 units, or 33.33 mcg per unit. Its share is 67%.
- Compound 2 is 5,000 mcg divided by 300 units, or 16.67 mcg per unit. Its share is 33%.
- A draw of 30 units contains 1,000 mcg of Compound 1 and 500 mcg of Compound 2.
If you enter targets for two components that need different numbers of units, the calculator says so under the table, since a single draw cannot match both.
Note: The calculator only does arithmetic on what you enter. It never tells anyone what to take. ChatPEP is for research only.
