MGF reconstitution calculator

How much bacteriostatic water to add to a MGF vial, what concentration that gives, and how many units to draw on a U-100 insulin syringe for your dose.

Vial mass

The total mg of compound in the vial as labelled by the supplier.

Bacteriostatic water

How much sterile bac water you'll add to reconstitute the vial.

Desired single dose

How much of the compound you want to take per injection.

Syringe size

U-100 syringes use the standard 100 units = 1 ml gradation.

Draw on syringe

2 units

Volume to draw

0.020 ml

Concentration

5.00 mg/ml

Doses per vial

100 doses

Draw to the 2-unit mark on a 100-unit insulin syringe.

A worked example

Take a 10 mg vial of MGF and the catalogue's typical dose of 100 mcg. Add 3 ml of bacteriostatic water and the vial holds 3.33 mg/ml, so one dose is 3 units on a U-100 insulin syringe.

3 units = 100 mcg

At once daily over 12 weeks that is 84 doses and 8.4 mg in total — 1 vial of 10 mg. One vial covers about 100 days at that rate, which is longer than the ~28 days a reconstituted peptide keeps in a fridge — a smaller vial wastes less. Storage on record — Refrigerate at 2-8°C; use within 30 days

What the catalogue records

Typical dose: 100-300mcg per injection
Frequency: Daily, immediately post-workout
Cycle duration: 8-12 weeks
Half-life: ~5-7 minutes
Storage: Refrigerate at 2-8°C; use within 30 days

Mixing a MGF vial

What you need

MGF lyophilized powder (typically 5mg vial)
Bacteriostatic water (3.0mL recommended)
Insulin syringes (29-31 gauge)
Alcohol swabs

Steps

Allow vial to reach room temperature
Clean rubber stopper with alcohol swab
Add 3.0mL bacteriostatic water for ~1.67mg/mL concentration
Inject slowly along vial wall, not directly onto powder
Gently swirl to dissolve; never shake
Store refrigerated at 2-8°C
Use within 30 days of reconstitution

Where this goes next

MGF — mechanism, dosing and safety — what it is, what the evidence says, and what it interacts with.
Build a cycle around it — the cycle builder runs this same arithmetic across every compound you add and totals the vials.
The general reconstitution calculator — the same tool with nothing prefilled.
