How Much BAC Water for MGF?

Quick answer: Add 2 mL of bacteriostatic water to a 2 mg MGF vial. This yields a concentration of 1000 µg/mL. A standard 200 µg research dose then requires 0.2 mL (20 IU on a 100-unit insulin syringe).

Concentration by BAC water volume

Concentration and 200 µg draw volume at common BAC water volumes for a 2 mg vial.

BAC water	Concentration	Dose volume	Draw
1 mL	2000 µg/mL	0.1 mL	10 IU
2 mL Standard	1000 µg/mL	0.2 mL	20 IU
3 mL	666.67 µg/mL	0.3 mL	30 IU
5 mL	400 µg/mL	0.5 mL	50 IU

Dose volume at the standard 1000 µg/mL concentration

How draw volume changes if you vary the dose at the standard 2 mg + 2 mL reconstitution.

Dose	Volume	IU draw (100u)
100 µg	0.1 mL	10 IU
200 µg Std	0.2 mL	20 IU
300 µg	0.3 mL	30 IU
400 µg	0.4 mL	40 IU
600 µg	0.6 mL	60 IU

Reconstitution steps

Wipe the top of both the MGF vial and the bacteriostatic water vial with alcohol swabs.
Draw 2 mL of bacteriostatic water into a sterile syringe.
Inject the water slowly down the inside glass wall of the MGF vial. Do not aim directly at the powder.
Swirl gently until fully dissolved. Never shake.
Refrigerate at 2-8°C protected from light. Allow to reach room temperature before each draw.

Supplies needed

Frequently asked

How much BAC water do I add to a 2 mg MGF vial?

For the standard ASCEND research protocol, add 2 mL of bacteriostatic water to a 2 mg MGF vial. This yields 1000 µg/mL.

What concentration does 2 mL BAC water give for 2 mg MGF?

A 2 mg MGF vial reconstituted with 2 mL of bacteriostatic water yields 1000 µg/mL. A 200 µg dose then requires 0.2 mL (20 IU on a 100-unit insulin syringe).

Can I use sterile water instead of bacteriostatic water for MGF?

Bacteriostatic water (0.9% benzyl alcohol) is preferred because it inhibits bacterial growth and allows multi-dose use of the reconstituted vial. Sterile water lacks preservative properties and accelerates peptide degradation once the vial is opened.

How long is MGF stable once reconstituted with BAC water?

Most research peptides remain stable for approximately 28 days when reconstituted with bacteriostatic water and stored at 2-8°C protected from light. Refer to peptide-specific stability data for any deviation from this baseline.

What size insulin syringe should I use for MGF?

For a 200 µg dose (20 IU draw), a 30-unit (0.3 mL) U-100 insulin syringe gives the finest resolution. A 100-unit syringe also works.

Can I transport reconstituted MGF?

Keep it cold in transit. An insulated bag or small cooler with an ice pack holds the 2-8°C range for several hours, which covers most day trips or drives. For longer travel, pack it the same way you would any refrigerated medication, and get it back into a fridge as soon as you arrive. Extended time at room temperature shortens the ~28-day stability window.
