BPC-157 dose to units reference (5 mg vial in 2 mL BAC water, U-100)
Common amounts people discuss, shown for reference. This is not a dosing recommendation. Use the amount your provider or protocol specifies. Concentration: 2,500 mcg/mL on a U-100 syringe.
| Dose | Volume (mL) | Units (U-100) |
|---|---|---|
| 250 mcg | 0.100 | 10 |
| 500 mcg | 0.200 | 20 |
| 750 mcg | 0.300 | 30 |
| 1000 mcg | 0.400 | 40 |
How to work out your BPC-157 units
The number of units you draw isn't about the dose alone, it's about how you mixed the vial. Reconstitute a 5 mg vial with 2 mL of bacteriostatic water and you've got 2,500 mcg per mL. A 250 mcg dose is 0.1 mL, which is 10 units on a U-100 syringe. Mix the same vial with 1 mL instead and every number on the syringe changes. So the rule is: set your mix first, then read the units off it. The calculator handles both steps once you enter your vial and water.
Common ways people reconstitute BPC-157
Most people use a 5 mg or 10 mg vial and somewhere between 1 and 3 mL of bacteriostatic water, picking the amount of water that makes their dose land on an easy number of units. There's no single "right" mix, it's about what's convenient to draw and store. A 5 mg vial in 2 mL is a common starting point because round doses come out to clean unit numbers. Whatever you choose, keep it consistent so your units mean the same thing every time.
Why units, not just mcg
Units are marks on the syringe that measure volume, how far up the barrel the liquid sits, not the amount of peptide. That's why "how many units is 250 mcg of BPC-157" has no fixed answer until you say how concentrated your solution is. Once you've entered your mix above, the units fall straight out of it.
Keep your vial size, water, and dose saved so you're not re-deriving units every time. Log your BPC-157 protocol in Regimen and your draw amount rides along with every shot.
Frequently Asked Questions
How many units of BPC-157 is 250 mcg?
It depends on your concentration. A 5 mg vial in 2 mL of bacteriostatic water is 2,500 mcg/mL, so 250 mcg is 0.1 mL, which is 10 units on a U-100 syringe. Enter your own mix above for your exact number.
How do you calculate a BPC-157 dose in units?
Work out your concentration (vial mcg divided by mL of water), divide your dose by that to get the volume in mL, then multiply by your syringe factor (100 for U-100). The calculator does all three steps.
How much bacteriostatic water do you add to a 5mg BPC-157 vial?
Commonly 1 to 3 mL. More water means a more dilute solution and more units per dose (easier to measure small amounts); less water means fewer units. Pick what makes your dose a clean number and stay consistent.
How many units is 500 mcg of BPC-157?
At 2,500 mcg/mL on a U-100 syringe, 500 mcg is 0.2 mL, or 20 units. Change your vial and water above for your exact figure.
How is BPC-157 dosed by body weight?
Some protocols discuss BPC-157 in mcg per kilogram of body weight, but the right number for you isn't something a calculator should hand you. Decide your dose with your provider or the protocol you're following, then enter it above to convert it into the exact units to draw. This tool organizes the dose you choose; it doesn't recommend one.
Does this tell me my BPC-157 dose?
No. It converts a dose you've already decided on into syringe units and shows commonly-discussed amounts for reference only. It doesn't recommend a dose, and BPC-157 isn't FDA-approved, so follow your provider or protocol.
