How much bac water for 80 mg Klow Blend?
Concentration and U-100 syringe unit chart for an 80 mg vial. Measurement arithmetic for preparing research solutions. For laboratory research use only.
Most labs add 3 mL of bacteriostatic water to an 80 mg Klow Blend vial, giving 26.67 mg/mL, so 10 units on a U-100 insulin syringe (0.1 mL) holds 2.67 mg. Alternatives: 1 mL gives 80 mg/mL; 1.5 mL gives 53.33 mg/mL; 2 mL gives 40 mg/mL. Less water gives a stronger solution and fewer units per draw; more water gives finer resolution per unit.
Most research vials are 3 mL serum vials, so about 3 mL is the practical maximum fill (leave a little headspace). If a lower concentration is needed, reconstitute in the vial and transfer to a larger sterile vial for further dilution.
80 mg Klow Blend reconstitution chart
Concentration = 80 mg divided by the mL of water added. On a U-100 insulin syringe, 100 units = 1 mL, so 10 units = 0.1 mL. Units for a given amount = amount / concentration x 100.
| Bac water added | Concentration | In 10 units (0.1 mL) | Units for 1 mg | Units for 2.5 mg | Units for 5 mg | Units for 10 mg |
|---|---|---|---|---|---|---|
| 1 mL | 80 mg/mL | 8 mg | 1.3 | 3.1 | 6.3 | 12.5 |
| 1.5 mL | 53.33 mg/mL | 5.33 mg | 1.9 | 4.7 | 9.4 | 18.8 |
| 2 mL | 40 mg/mL | 4 mg | 2.5 | 6.3 | 12.5 | 25 |
| 2.5 mL | 32 mg/mL | 3.2 mg | 3.1 | 7.8 | 15.6 | 31.3 |
| 3 mL | 26.67 mg/mL | 2.67 mg | 3.8 | 9.4 | 18.8 | 37.5 |
Highlighted row = the common default for this vial. Unit values are on a U-100 insulin syringe (100 units = 1 mL), rounded to 0.1 unit; read to the nearest graduation your syringe has.
Per-component concentration
Each 80 mg vial of Klow Quad Stack contains GHK-Cu 50 mg, BPC-157 10 mg, TB-500 10 mg, KPV 10 mg (the standard formulation for this blend; confirm against the label on your lot). Every component is diluted by the same volume, so each one's concentration is its own mass divided by the water added.
| Bac water added | Total blend | GHK-Cu (50 mg) | BPC-157 (10 mg) | TB-500 (10 mg) | KPV (10 mg) |
|---|---|---|---|---|---|
| 1 mL | 80 mg/mL | 50 mg/mL | 10 mg/mL | 10 mg/mL | 10 mg/mL |
| 1.5 mL | 53.33 mg/mL | 33.33 mg/mL | 6.67 mg/mL | 6.67 mg/mL | 6.67 mg/mL |
| 2 mL | 40 mg/mL | 25 mg/mL | 5 mg/mL | 5 mg/mL | 5 mg/mL |
| 2.5 mL | 32 mg/mL | 20 mg/mL | 4 mg/mL | 4 mg/mL | 4 mg/mL |
| 3 mL | 26.67 mg/mL | 16.67 mg/mL | 3.33 mg/mL | 3.33 mg/mL | 3.33 mg/mL |
At the default 3 mL, 10 units (0.1 mL) contains: GHK-Cu 1.67 mg, BPC-157 333.3 mcg, TB-500 333.3 mcg, KPV 333.3 mcg.
How to reconstitute 80 mg Klow Blend
- Equilibrate. Let the sealed vial and the bacteriostatic water reach room temperature (about 15 to 20 minutes) to limit condensation and help the powder dissolve.
- Swab both stoppers. Wipe the rubber stopper of the peptide vial and of the water vial with a fresh alcohol swab and let them air-dry.
- Measure the water. Draw 3 mL of bacteriostatic water (or your chosen volume from the chart) with a sterile syringe.
- Add it down the vial wall. Insert the needle through the stopper at an angle and release the water slowly down the inside wall of the vial, not directly onto the powder.
- Swirl, do not shake. Gently swirl or roll the vial until the powder is fully dissolved and the solution is clear. Allow a few minutes; some peptides dissolve slowly.
- Label it. Write the date and the concentration (26.67 mg/mL at the default volume) on the vial.
- Refrigerate. Store the reconstituted vial at 2 to 8 °C, protected from light.

Storage after reconstitution
- Keep the reconstituted vial at 2 to 8 °C (refrigerator, not the door), protected from light.
- Lumera's product pages list 28 days at 2 to 8 °C in the original vial; follow the window on the lot's COA. Bacteriostatic water's benzyl alcohol limits microbial growth across repeated stopper punctures; sterile water does not.
- Do not refreeze the working vial. For longer holding, divide into aliquots once and freeze, avoiding repeated freeze-thaw cycles.
- Unopened lyophilized vials keep best frozen (-20 °C). See the peptide storage temperature guide.
Troubleshooting
The solution is cloudy
Give it time: let the vial stand in the fridge for 15 to 30 minutes and swirl gently again. If cloudiness, particles or a colour change persist after the powder has dissolved, do not use the solution for quantitative work; discard it.
Foam or bubbles
Usually caused by shaking or by streaming water onto the powder. Let the vial rest upright in the fridge until the foam settles, and next time add the water slowly down the vial wall and swirl instead of shaking.
Left out at room temperature overnight
Degradation speeds up at room temperature, and how much is lost varies by peptide. Return the vial to 2 to 8 °C, note the excursion on the label, and for work where exact concentration matters, prepare a fresh vial.

How much bacteriostatic water do I add to 80 mg Klow Blend?
Most labs add 3 mL, which gives 26.67 mg/mL. Alternatives: 1 mL gives 80 mg/mL; 1.5 mL gives 53.33 mg/mL; 2 mL gives 40 mg/mL. The volume is a choice; what matters is recording the resulting concentration on the vial label.
How many units is 5 mg of Klow Blend in a 3 mL mix?
At 26.67 mg/mL, 5 mg is in 18.8 units on a U-100 insulin syringe (0.188 mL). Units = amount / concentration x 100.
What concentration does 80 mg Klow Blend make with 2 mL of water?
80 mg divided by 2 mL is 40 mg/mL, so each 10 units (0.1 mL) holds 4 mg.
How long does reconstituted Klow Blend last in the fridge?
Lumera's product pages list reconstituted solutions as stable for 28 days at 2 to 8 °C in the original vial, protected from light. Use within the window noted on the lot's COA and discard if the solution turns cloudy, changes colour or shows particles.
Should I shake the Klow Blend vial to dissolve it?
No. Swirl or roll the vial gently and let it stand a few minutes. Shaking creates foam and can degrade peptides.
