Peptide Reconstitution Chart

You can skip the scrap paper by the cupboard door. This peptide reconstitution chart turns vial mg and liquid mL into mg per mL and, on a U-100 scale, mcg per unit. For example, a 10 mg vial mixed with 2 mL gives 5 mg per mL and 50 mcg per unit.

Chart: mg per mL

Use this chart as a lookup table. Find your vial mg on one side, find your liquid mL across the top, and read the mg per mL where they meet.

If your numbers aren't in the grid, you can enter your own numbers. Write the result beside your label if that helps.

Chart: mcg per unit on a U-100 syringe

This chart shows the same vial and liquid combinations as mcg per unit on a U-100 scale. MedlinePlus: Giving an insulin injection (opens in a new tab) says standard insulin contains 100 units in 1 mL. ADA: Overview of Insulin Concentration for School Nurses (opens in a new tab) says the syringe must match the vial concentration.

Check the label words carefully. mg, mL, and units are different things. To read the barrel itself, see how to read your syringe, and if your combination is missing, enter your own numbers.

How to use the chart

The chart does one piece of arithmetic. It turns vial strength and liquid volume into a concentration you can read back later on your plan or your notes.

  1. Read the mg printed on your vial.
  2. Read the mL on your label or plan.
  3. Find that row and column in the chart.
  4. Note the mg per mL result.
  5. Read the matching mcg per unit result if you use a U-100 scale.
  6. Write the result down with the date.

That is the math behind how to reconstitute peptides: the math. For preparation, storage, or technique, follow the label and ask your pharmacist or prescriber.

Example reading: 10 mg in 2 mL = 5 mg per mL. Example reading: 10 mg in 2 mL = 50 mcg per unit on a U-100 syringe. Example reading: 30 mg in 3 mL = 10 mg per mL. Example reading: 30 mg in 5 mL = 6 mg per mL.

These are examples of reading the marks, not an amount to take.

If you want to check the syringe scale by eye, count the lines between two printed numbers on your own barrel and divide. Then line up the tip of the plunger with the line, and follow your own syringe's instructions.

Why this chart has no amounts

This page converts what is already printed on your vial and label. It does not tell you what amount to use.

That's why the chart starts with mg and mL, not a schedule. It helps you translate packaging into concentration and into a U-100 unit reading when that matches your syringe. ADA: Overview of Insulin Concentration for School Nurses (opens in a new tab) notes that U-100 means 100 units in 1 mL and that the syringe and vial concentration need to match.

Questions

How to figure out reconstitution?

Use 3 steps, and this peptide reconstitution chart covers the first one for common vial and liquid sizes. Divide mg in the vial by mL of liquid to get mg per mL. MedlinePlus: Giving an insulin injection (opens in a new tab) says standard insulin contains 100 units in 1 mL, so you can convert your mL amount to U-100 units.

How to reconstitute 30 mg of peptides?

For the arithmetic, 30 mg in 3 mL is 10 mg per mL, and 30 mg in 5 mL is 6 mg per mL. Find the 30 mg row in the chart. For preparation steps, follow your label and ask your pharmacist or prescriber.

Read this first. Math based on your entries. This page does arithmetic on the numbers you type. It does not recommend an amount, a schedule or a product. Check every result against your label and talk to your prescriber or pharmacist. 18+.
