MGF Dosage Calculator & Research Doses

1Set Up Your Mix

1.667 mg/mL · 1667 mcg/mL

1. Pick your peptide

2. How much peptide is in the vial? It's printed on the label — usually something like 5 mg

3. How much water are you adding? More water makes each dose easier to measure

4. How much do you want per dose?

Your Answer — MGF

5 mg in 3 mL

25Doses In The Vial

5 mg ÷ 3 mL = 1.667 mg/mL → 200 mcg ÷ 1.667 mg/mL = 0.12 mL → × 100 = 12 units

Looks good. Draw to 12 units on a 1 mL syringe. That is an easy amount to measure, and this vial gives you 25 doses.

When to dose

Time of dayNo particular time of day has been established.

FoodNo fasting requirement has been established.

The studies behind this compound did not test timing or food state as variables, so we are not going to invent a rule. Pick a time you can keep to consistently.

Where this plan came from

Built from this peptide's dose range

Where this came from: Built from the doses listed for this peptide below — start at the lowest and step up, using the studies cited on this page. Nobody publishes a week-by-week plan for this peptide, so we built one: the doses are the researched ones shown below, and we simply put them in order from lowest to highest. Treat it as a starting point, not an official schedule.

Common Questions — MGF

How much bacteriostatic water do I add to a 5 mg vial of MGF?

Adding 3 mL of bacteriostatic water to a 5 mg vial gives 1.67 mg/mL. That is the mix every number on this page is worked out from — change the water figure in the calculator and all the draw amounts update.

What dose of MGF is used in research?

Published and reported figures for MGF run from 200 mcg to 400 mcg, typically post-training. This site lists each figure with the source it came from rather than giving a single recommended number.

How many units on the syringe is a 200 mcg dose of MGF?

At 1.67 mg/mL, a 200 mcg dose is 12 units on a 1 mL U-100 insulin syringe. One vial at that mix gives about 25 doses.

How strong is the evidence behind these MGF doses?

MGF is graded preclinical. Laboratory and animal data only. No human dosing trials have been published. We grade every compound on this site so you can weigh the numbers accordingly — the full method is on our editorial policy page.
