Peptide Dosage Chart

If you would rather look a number up than calculate it, this is your page. Find your vial, find your mix, read off the draw. Rows that will not fit in a syringe, or are too small to read properly, are flagged in the table instead of being quietly left there.

How to read it

Each small table is one mix: a vial size and the water added to it. The heading gives you the concentration that mix produces, because the concentration is what connects the dose column to the units column. Doses are listed in mcg and mg side by side. They are the same amounts in two units, and having both there stops the thousand-times mix-up between them.

About the flags. "Over one full syringe" means exactly that: correct number, impractical draw. "Hard to read" means the draw is real but tiny. Both problems are solved the same way, by picking a different amount of water before you mix. The reconstitution calculator picks it for you.

Per-compound charts

These tables are organised by mix, so they work for any compound that comes in a 5 or 10 mg vial. If you want a specific compound with its own vial sizes loaded and ready, open its preset in the calculator instead:

Retatrutide Vials 5 to 60 mg, dose to units preset Tirzepatide Vials 5 to 60 mg, dose to units preset Semaglutide Vials 5 to 30 mg, dose to units preset BPC-157 Vials 5 to 10 mg, dose to units preset

Common questions

How do I read this chart?

Find your vial size first, then the table for the amount of water you added. Your dose is in the left column. Read across and the units column tells you what to draw on a U-100 syringe. The mL column is the same draw written as a volume, useful if your syringe is marked in mL instead.

My vial size or mix is not on the chart. What now?

The chart sticks to the mixes people ask about most: 5 and 10 mg vials with 1, 2 or 3 mL of water. Anything else is the same maths with different inputs, and the peptide calculator handles any vial, any amount of water and any dose.

Why do some rows say the draw is over 100 units?

Because it is. At that mix, that dose is more than 1 mL of liquid, and 1 mL is all a standard U-100 syringe holds. The number is not wrong, the mix is just weak for a dose that size. If you have not mixed yet, less water makes the same dose a smaller draw.

Why are some draws flagged as hard to read?

A small dose in a strong mix comes out as 2 or 3 units, and at that size the barrel markings are too close together to measure accurately. Mixing with more water stretches the same dose over more units. The flag is there so you can spot the problem before mixing, not after.

Is the PDF the same as this page?

Yes. The PDF is generated from the same engine as the tables on this page, so the numbers match exactly. It is free, and it carries the same reminder the page does: units measure volume, not dose.

Arithmetic only

This calculator does maths on the numbers you enter. It works out concentration, draw volume and syringe units from the vial amount and water volume you give it. Nothing more.

It does not recommend amounts, schedules or products, and it does not know what is in your vial. It uses the amount printed on the label. If the label and the actual contents differ, the result differs too. For medical questions, talk to a clinician.
