Bacteriostatic water, 10ml →Understanding units
The calculator tells you how many units to draw. Here is exactly what a unit is, and why it means the same thing on every insulin syringe.
On a U-100 insulin syringe one unit is a hundredth of a millilitre. So 10 units is 0.1 mL, and 100 units is 1 mL. Units simply make very small volumes easier to read off the barrel.
It does not matter which insulin syringe you pick up. Drawing to 20 units pulls the same 0.2 mL on a 0.3 mL, a 0.5 mL or a 1 mL syringe. The tick marks never change size.
What changes between syringes is how many of those marks fit on the barrel. A bigger syringe is not a bigger unit, it is just more room.
Example: a 20-unit draw is 0.2 mL on all three syringes above. The only difference is how much empty barrel is left behind it.

How the BPC-157 calculator works
BPC-157 is a synthetic peptide of fifteen amino acids, supplied as a lyophilized powder that has to be mixed with bacteriostatic water before use. This BPC-157 calculator opens on a 10mg vial with 2mL of water loaded and converts the result into a concentration and a syringe reading. Change the vial, the water or the syringe size and every figure updates. The amount field starts empty because the amount belongs to the protocol a researcher is working to.
BPC-157 reconstitution and the mcg per unit shortcut
A 10mg vial holds 10,000mcg, and amounts of BPC-157 are usually written in micrograms, so the useful number is micrograms per syringe unit. Multiply the concentration in mg/mL by 10 to get it:
- 10mg vial in 1mL gives 10mg/mL, which is 100mcg per unit
- 10mg vial in 2mL gives 5mg/mL, which is 50mcg per unit
- 10mg vial in 4mL gives 2.5mg/mL, which is 25mcg per unit
- 10mg vial in 5mL gives 2mg/mL, which is 20mcg per unit
Switch the calculator to mcg and type the amount directly. The result is the number of units to draw, with no mental conversion between milligrams and micrograms in the middle.
BPC-157 dosage calculator: from micrograms to units
The method is the same two divisions as every other peptide. Divide the amount by the concentration to get the volume in mL, then multiply by 100 for units. At 5mg/mL, 1,000mcg is 1mg, which is 0.2mL and 20 units. The doses-in-vial figure divides 10,000mcg by the amount, so the same vial holds ten of those draws. If a reading falls under 2 units, add water and the calculator will confirm the new figure.
Check what is actually in the vial
Every figure starts from the strength printed on the vial, so confirm it against the certificate of analysis for your batch. Healio publishes each one on the research page, and how to read a certificate of analysis explains which figures actually prove something. Repackaged product is a real problem with this compound, and how to tell real BPC-157 peptides from repackaged covers what to look for. Once the vial is mixed, write the water volume, the concentration and the date on the label. Our guide to reconstituting peptides covers the handling, and how long bacteriostatic water lasts covers the in-use window.
BPC-157 for sale from Healio is stocked as a 10mg vial. It is often discussed alongside another compound, so see the TB-500 calculator and BPC-157 and TB-500. The all-peptide calculator handles any other vial strength.
BPC-157 calculator FAQ
How much bacteriostatic water goes in a 10mg BPC-157 vial?
It is a choice, not a fixed answer. 1mL gives 10mg/mL, 2mL gives 5mg/mL and 4mL gives 2.5mg/mL. The volume sets the concentration, which sets where an amount sits on the syringe scale.
How many mcg are in a 10mg BPC-157 vial?
There are 10,000mcg in 10mg. Divide that by the amount you are working to and you get the number of draws the vial holds on paper. The calculator shows it as doses in vial.
How many units is 1,000mcg of BPC-157?
It depends on the concentration. At 5mg/mL, 1,000mcg is 1mg, which is 0.2mL and 20 units on a U-100 syringe. At 10mg/mL the same amount is 10 units.
What is the quickest way to check the calculator result?
Multiply the concentration in mg/mL by 10 to get micrograms per unit. At 5mg/mL that is 50mcg per unit, so 1,000mcg is 20 units. If your result matches, the arithmetic is right.
Does the calculator recommend an amount of BPC-157?
No. It converts the figures you enter and makes no recommendation. Healio supplies research compounds for laboratory use, so quantities belong to the protocol a researcher is working to.
Can I calculate BPC-157 and TB-500 together?
Treat each vial separately. Each has its own strength and its own water volume, so run them one after the other, or open the TB-500 calculator in a second tab.
