Blends & stacks dosage calculator
Blends & stacks vials are commonly labelled 5 mg, 10 mg. This calculator divides the vial mass by the diluent volume you enter to show concentration, then converts your own target amount into millilitres and syringe units. It states no dose, chooses no amount and stores nothing.
This page is a calculation tool. The amounts you enter are values you decided; this page states no dose and gives no medical advice.
Blends & stacks vial concentration grid
This table answers one arithmetic question: what concentration results when a labelled vial mass is divided by a measured diluent volume? It does not select either value.
| Vial mass | Diluent | Concentration | Same concentration |
|---|---|---|---|
| 5 mg | 0.5 mL | 10,000 mcg/mL | 10 mg/mL |
| 5 mg | 1 mL | 5,000 mcg/mL | 5 mg/mL |
| 5 mg | 1.5 mL | 3,333.33 mcg/mL | 3.333 mg/mL |
| 5 mg | 2 mL | 2,500 mcg/mL | 2.5 mg/mL |
| 5 mg | 2.5 mL | 2,000 mcg/mL | 2 mg/mL |
| 5 mg | 3 mL | 1,666.67 mcg/mL | 1.667 mg/mL |
| 5 mg | 5 mL | 1,000 mcg/mL | 1 mg/mL |
| 10 mg | 0.5 mL | 20,000 mcg/mL | 20 mg/mL |
| 10 mg | 1 mL | 10,000 mcg/mL | 10 mg/mL |
| 10 mg | 1.5 mL | 6,666.67 mcg/mL | 6.667 mg/mL |
| 10 mg | 2 mL | 5,000 mcg/mL | 5 mg/mL |
| 10 mg | 2.5 mL | 4,000 mcg/mL | 4 mg/mL |
| 10 mg | 3 mL | 3,333.33 mcg/mL | 3.333 mg/mL |
| 10 mg | 5 mL | 2,000 mcg/mL | 2 mg/mL |
How to use the calculator
- Read the total mass from your own vial label and enter it in milligrams.
- Enter the diluent volume you actually measured, not an intended or remembered value.
- Enter your own target amount and select the calibration printed on your syringe barrel.
- Record the concentration with the result so the syringe-unit figure remains interpretable later.
Source and identity record
Use the compound reference page and these external database searches when checking identity: PubMed literature search for Blends & stacks. A database record does not authenticate a vial.
Frequently asked questions
How much bacteriostatic water for a 5 mg Blends & stacks vial?
This calculator does not choose a diluent volume. Enter the volume you decided to add to the 5 mg vial and it will show the resulting concentration. The page supplies arithmetic, not an instruction.
How much bacteriostatic water for a 10 mg Blends & stacks vial?
There is no universal volume selected by this page. Use the value you measured or were instructed to use; the calculator then divides the 10 mg label mass by that volume.
Does the Blends & stacks calculator recommend a dose?
No. The target amount is always entered by the user. The tool provides no starting amount, maximum amount, progression, frequency or schedule.
Why does the syringe calibration matter?
A syringe unit is a volume marking. U-100, U-50 and U-40 barrels use different numbers of units per millilitre, so the same solution volume produces different markings.

PepCycle stores each vial once — mass, diluent volume, concentration — and converts automatically for every entry after that, in both directions, including entries you backdate.
