How to reconstitute KLOW
KLOW is a four-peptide blend sold as one 80 mg vial: 50 mg GHK-Cu plus 10 mg each of BPC-157, TB-500 and KPV. Every amount you draw holds them in the same 5 : 1 : 1 : 1 ratio, so the chart gives the total and each peptide's share. The mixed liquid turns blue from the copper in GHK-Cu. Labels differ between makers; this chart is for the 50/10/10/10 split, and the calculator takes any other.
- 80 mg (50/10/10/10) vial: add 3 mL of bacteriostatic water. That makes 26.67 mg/mL, so each unit on a U-100 insulin syringe holds 266.7 mcg, and 3.2 mg is 12 units.

Step by step
The same steps as the video, in writing.
- Check the label.
The vial says how much powder is in it: 80 mg (50/10/10/10). For a blend, the label gives the total and the split: GHK-Cu + BPC-157 + TB-500 + KPV.
- Draw the water.
Use bacteriostatic water: 3 mL for the 80 mg (50/10/10/10) vial. If it's more than 1 mL, a 3 mL syringe does it in one draw.
- Add it slowly.
Let the water run down the inside wall of the vial, then swirl gently until the powder has dissolved. Don't shake it.
- Write the strength on the vial.
For the 80 mg (50/10/10/10) vial that's 26.67 mg/mL, or 266.7 mcg per unit, plus the date you mixed it.
- Find your amount.
Read the units from the chart, or put your own numbers in the calculator. Then check it backwards: units × mcg per unit should give the amount you wanted.

Questions
How much bacteriostatic water do you add to an 80 mg (50/10/10/10) KLOW vial?
In the Reconstitution Insights video, Matthew adds 3 mL. That makes 26.67 mg/mL, so each unit on a U-100 insulin syringe holds 266.7 mcg. You can use more or less water: the amount of peptide in the vial stays the same, only what each unit holds changes. The calculator works it out for any amount.
How many units do I draw for an amount of KLOW?
Divide the amount you want (in mcg) by what one unit holds. For example, 3.2 mg from the 80 mg (50/10/10/10) vial mixed with 3 mL is 12 units (0.12 mL). The chart above lists the other amounts.
What is a unit on an insulin syringe?
U-100 insulin syringes are marked in units: 100 units is 1 mL, so 1 unit is 0.01 mL whatever the size of the syringe. A 0.3 mL syringe holds 30 units and a 0.5 mL syringe holds 50.
Is this dosing advice?
No. The amounts are examples for the arithmetic, not recommendations. This page is for research and education only and isn't medical advice.
