For the BPC-157 10 mg vial. Enter the bacteriostatic water you add and the amount you want, and see exactly where to draw on the syringe, in units and mL.
1 mg = 1,000 mcg. Type any amount, or tap a common one.
Almost all insulin-style syringes are U-100. Check the packaging if you're not sure.

What each mark on the syringe holds with this mix.
BPC-157 (Body Protection Compound) is a 15-amino-acid synthetic peptide and one of the most widely studied compounds in preclinical tissue-repair research. CoreVionRX supplies it as a 10 mg lyophilized vial, so every calculation on this page starts from 10 mg.
Because research amounts are usually written in micrograms, the most common mix-up is mcg versus mg: 250 mcg is 0.25 mg. With 2 mL of bacteriostatic water, a 10 mg vial is 5 mg/mL and every unit on a U-100 syringe holds 50 mcg, which keeps the numbers easy to read. For laboratory research use only.

Every reconstitution calculator uses the same three steps. Here they are in plain numbers, so you can check any result by hand.
mg in vial ÷ mL of water = mg/mL10 mg + 2 mL of bacteriostatic water = 5 mg/mL. The water changes the strength, not the amount of peptide.
amount you want ÷ strength = mLFor 250 mcg (0.25 mg): 0.25 ÷ 5 = 0.05 mL.
mL × 100 = units (U-100)0.05 mL × 100 = 5 units. On a U-100 syringe, 1 unit is always 0.01 mL, whatever the barrel size.
Same vial, different amounts of water. More water spreads the same peptide across more liquid, so each mark holds less and draws get bigger.
| Water added | Strength | 10 units holds | 250 mcg = |
|---|---|---|---|
| 1 mL | 10 mg/mL | 1 mg | 2.5 units |
| 2 mL | 5 mg/mL | 500 mcg | 5 units |
| 3 mL | 3.33 mg/mL | 333 mcg | 7.5 units |
| 5 mL | 2 mg/mL | 200 mcg | 12.5 units |
Each one opens with the right vial size and shows the numbers for that peptide.
There is no single correct amount: water changes the strength, not how much peptide is in the vial. For example, with 2 mL the vial is 5 mg/mL and every 10 units holds 500 mcg; with 3 mL the vial is 3.33 mg/mL and every 10 units holds 333 mcg. More water makes each draw larger and easier to measure. A common choice for this vial is 2 mL.
With 2 mL of water in the 10 mg vial, 250 mcg is 5 units (0.05 mL) on a U-100 syringe. A different amount of water gives a different answer, so enter your own numbers in the calculator above.
At 250 mcg per draw there are 40 draws (10 mg ÷ 0.25 mg). The water amount does not change this number, only the size of each draw.
Plan on about one week in the fridge (2–8°C) as a conservative standard. For longer, split the solution into single-use portions and freeze them, avoiding repeated freeze-thaw cycles. Keep the unmixed powder cold, dry and dark.
mcg and mg measure how much peptide you have (1 mg = 1,000 mcg). mL measures liquid. Units are just the markings on an insulin-style syringe: on a U-100 syringe, 1 unit = 0.01 mL, so 100 units = 1 mL.
No. 0.3 mL, 0.5 mL and 1 mL insulin syringes are all U-100: 1 unit is always 0.01 mL. Only the barrel size changes. Smaller barrels have finer markings, which makes small draws easier to read.
