How much bacteriostatic water for a 2 mg PEG-MGF vial?

The amount of water does not change how much PEG-MGF is in the vial; it sets the concentration. With 1 mL a 2 mg vial is 2 mg/mL, with 2 mL it is 1 mg/mL and with 3 mL it is 0.667 mg/mL. More water makes each unit weaker, so a given amount takes more units to draw.

How many mcg are in one unit of a 2 mg PEG-MGF vial?

With 2 mL of water, one unit on a U-100 syringe holds 10 mcg (1,000 mcg per mL divided by 100). The table above gives the figure for other vial sizes and volumes.

Is this a PEG-MGF dosage calculator?

It converts between amounts, volumes and syringe units for PEG-MGF; it does not suggest how much to use. The PEG-MGF guide lists the doses used in published studies, with their sources.

What size are PEG-MGF vials?

Across 117 listings in our directory, the most common sizes are 2 mg, 5 mg, 20 mg, 10 mg. Sizes and prices by store are on the PEG-MGF price page.

How many units are in 1 mL on an insulin syringe?

A U-100 insulin syringe holds 100 units per mL, so 1 unit is 0.01 mL.

PEG-MGF dosage calculator

Pick a PEG-MGF vial size, enter the bacteriostatic water added and, if you want, an amount per draw. The calculator gives the concentration and how many units that is on a U-100 insulin syringe. It does arithmetic only and does not suggest an amount.

U-100 syringes · 100 units = 1 mL · 1 mg = 1,000 mcg

Concentration

10 mcg per unit on a U-100 syringe · 100 mcg per 0.1 mL

Enter an amount per draw to see how many units it is and how many draws the vial holds.

Worked example

A 2 mg PEG-MGF vial with 2 mL of bacteriostatic water is 1 mg/mL (1,000 mcg/mL). One unit on a U-100 syringe is 0.01 mL, so each unit holds 10 mcg. To find how many units an amount is, divide the amount in mcg by 10.
