This calculator performs arithmetic on the numbers you enter. It is not medical advice, does not tell you what dose to take, and is not a substitute for guidance from a qualified clinician.
KLOW ships as a single lyophilized vial holding four peptides — GHK-Cu, KPV, BPC-157, and TB-500 — at a fixed ratio, so the vial's total mg is what sets the concentration, not any one component alone. This chart lays out that math at a standard vial size and water volume. It is a reference for research and educational purposes only and is not medical advice.
The reference vial
A KLOW vial is commonly supplied at an 80 mg total, split 50/10/10/10 across the four peptides — a 5:1:1:1 ratio:
| Component | Amount |
|---|---|
| GHK-Cu | 50 mg |
| KPV | 10 mg |
| BPC-157 | 10 mg |
| TB-500 | 10 mg |
| Total | 80 mg |
Reconstitution dissolves all four into one solution, so every draw pulls the blend at that same 5:1:1:1 ratio. For the component-level breakdown of a given draw, see the KLOW peptide blend dosage guide.
Vial-to-concentration chart
A common research setup adds 3 mL of bacteriostatic water to the 80 mg vial:
| Vial total | Water added | Concentration |
|---|---|---|
| 80 mg (50/10/10/10 KLOW) | 3 mL | ≈26.7 mg/mL |
More water lowers the concentration and produces a larger, easier-to-read draw. Less water raises the concentration and shrinks the draw. The 5:1:1:1 ratio between components stays fixed regardless of water volume — water changes concentration, not composition.
Dosage chart by target dose
Each row assumes the 26.7 mg/mL reference concentration above and shows the resulting draw on a U-100 insulin syringe (100 units per mL).
| Target dose | Volume | Units |
|---|---|---|
| 0.5 mg | 0.0188 mL | 1.9 units |
| 1 mg | 0.0375 mL | 3.75 units |
| 2 mg | 0.075 mL | 7.5 units |
| 2.5 mg | 0.094 mL | 9.4 units |
| 4 mg | 0.15 mL | 15 units |
These figures hold only for the 80 mg / 3 mL reference setup. A different vial total or water volume shifts every number in the chart.
Reading the chart against your vial
Worked example. An 80 mg KLOW vial mixed with 3 mL of water sits at about 26.7 mg/mL. A 2 mg total dose from that vial is 2 ÷ 26.7 ≈ 0.075 mL, or 7.5 units. That same 2 mg draw splits across components at the vial's 5:1:1:1 ratio — 1.25 mg GHK-Cu, 0.25 mg KPV, 0.25 mg BPC-157, and 0.25 mg TB-500 — covered in full in the KLOW peptide blend dosage guide.
If your vial's total mg or water volume differs from the reference, this chart's unit counts don't apply directly. Enter your own vial total, water volume, and target dose into the peptide reconstitution calculator for an exact reading, or use its reverse mode to solve for the water volume that lands a dose on a round unit mark.
Common mistakes
- Treating the chart's dose as a single peptide's amount. A "2 mg KLOW dose" is 2 mg of combined blend split 5:1:1:1, not 2 mg of any one component.
- Applying this chart to a differently-sized KLOW vial. The unit counts here are only valid at the 80 mg / 3 mL reference point.
- Confusing KLOW's concentration with GLOW's. GLOW is a 70 mg vial (no KPV), so the same 3 mL water volume produces a different mg/mL in each blend.
- Shaking instead of swirling during reconstitution. See how to reconstitute peptides for the mixing steps.
Use the calculator
Enter your KLOW vial's total mg, bacteriostatic water volume, and target dose into the peptide calculator for an exact unit count at any concentration, not just the reference numbers in this chart. For the general vial-size math across other peptides, see peptide dosage chart by vial size; for the component-level KLOW breakdown, see the KLOW peptide blend dosage guide.
Frequently Asked Questions
- What does a KLOW peptide dosage chart assume for water volume?
- A common reference setup uses 3 mL of bacteriostatic water for the standard 80 mg KLOW vial (50 mg GHK-Cu, 10 mg KPV, 10 mg BPC-157, 10 mg TB-500), which works out to about 26.7 mg/mL. A different water volume changes the concentration and every unit reading in the chart.
- How many units is a 2 mg KLOW dose on the chart?
- At the 26.7 mg/mL reference concentration (80 mg vial, 3 mL water), a 2 mg total dose is about 7.5 units on a U-100 insulin syringe. A 1 mg dose is about 3.75 units.
- Does the chart show each peptide in KLOW separately?
- No. The chart tracks the blend's total mg, since that is what a single draw pulls from a premixed vial. The KLOW peptide blend dosage guide breaks a given draw down into its GHK-Cu, KPV, BPC-157, and TB-500 shares.
- What if my KLOW vial isn't 80 mg?
- The chart's numbers only hold at the 80 mg / 3 mL reference point. For any other vial total or water volume, enter your own numbers into the peptide calculator rather than reusing this chart's unit counts.
