For the KLOW blend 80 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. Measure by the whole blend or by one ingredient.
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.
KLOW is an 80 mg research blend in a single vial: 50 mg GHK-Cu, 10 mg BPC-157, 10 mg TB-500 and 10 mg KPV. Blends are where most reconstitution mistakes happen, because the amount on a protocol usually refers to one ingredient, not the whole vial.
This calculator opens set to measure by BPC-157, the way KLOW amounts are most often written. Switch to "Whole blend" or another ingredient at any time; the table under the results shows exactly how much of each ingredient is in every draw. 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/mLBPC-157 is 10 mg of the 80 mg blend. With 3 mL of water: 10 ÷ 3 = 3.33 mg/mL of BPC-157.
amount you want ÷ strength = mLFor 250 mcg (0.25 mg): 0.25 ÷ 3.33 = 0.075 mL.
mL × 100 = units (U-100)0.075 mL × 100 = 7.5 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 BPC-157 = |
|---|---|---|---|
| 1 mL | 80 mg/mL | 8 mg | 2.5 units |
| 2 mL | 40 mg/mL | 4 mg | 5 units |
| 3 mL | 26.67 mg/mL | 2.67 mg | 7.5 units |
| 5 mL | 16 mg/mL | 1.6 mg | 12.5 units |
| Ingredient | Per vial | Share | Per 10 units (3 mL water) |
|---|---|---|---|
| GHK-Cu | 50 mg | 62.5% | 1.67 mg |
| BPC-157 | 10 mg | 12.5% | 333 mcg |
| TB-500 | 10 mg | 12.5% | 333 mcg |
| KPV | 10 mg | 12.5% | 333 mcg |
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 40 mg/mL and every 10 units holds 4 mg; with 3 mL the vial is 26.67 mg/mL and every 10 units holds 2.67 mg. More water makes each draw larger and easier to measure. A common choice for this vial is 3 mL.
With 3 mL of water in the 80 mg vial, 250 mcg is 7.5 units (0.075 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.
KLOW contains 50 mg GHK-Cu, 10 mg BPC-157, 10 mg TB-500, 10 mg KPV (80 mg total) in one vial. The ingredients dissolve together, so every draw carries all of them in the same ratio. With 3 mL of water, a 7.5-unit draw holds 1.25 mg GHK-Cu, 250 mcg BPC-157, 250 mcg TB-500, 250 mcg KPV.
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.
