PEG-MGF Dosage Chart & Schedule
A pegylated form of Mechano Growth Factor, a splice variant of IGF-1 linked to muscle repair. Human data are limited and its use is investigational.
PEG-MGF has no established human dosing and is investigational. Research-community references use roughly 200-400 mcg subcutaneously, often 1-3 times weekly, with the PEG chain intended to stretch the minutes-long native MGF window into hours.
Figures describe how PEG-MGF is reported in the research literature and research-community references — not a recommendation for human use. For laboratory research only.
Dosage protocols
Commonly referenced research tiers. Start conservative; every compound and study context differs.
- Frequency
- 1-2x/week
- Weekly total
- ~200-600 mcg/week
- Cycle
- Several-week blocks
Mid-range of the referenced 200-400 mcg per-dose figures.
- Frequency
- up to 3x/week
- Weekly total
- up to ~1200 mcg/week
- Cycle
- Several-week blocks
Upper community reference; not clinically validated.
PEGylation is the whole point
- Native MGF is cleared within minutes.
- The attached PEG chain is intended to extend exposure to hours or longer.
- Human pharmacokinetic data confirming this are lacking.
Investigational only
- There is no established human dose.
- The 200-400 mcg figures come from research-community sources, not clinical trials.
Ready to run this protocol?
Dosing is only as good as the vial. Research-grade peptides are third-party tested with published COAs from our top-rated source — reconstitute with confidence and skip the guesswork on identity and purity.
Weekly schedule
A typical week on the standard (community) protocol (1-2x/week).
Dosing day Off
PEG-MGF reconstitution
5 mg vial + 2 mL bacteriostatic water = 2500 mcg/mL.
From vial to injection in 6 steps
Wipe both vial tops
Swab the peptide vial and the bacteriostatic-water vial with fresh alcohol and let them dry.
Draw the water
Pull the planned amount of bacteriostatic water (2 mL) into the syringe.
Add it slowly
Run the water down the inside wall of the vial — don't blast the powder. Swirl gently; never shake.
Let it dissolve
Wait until the solution is fully clear, then refrigerate the vial.
Draw your dose
Pull the calculated units on a U-100 insulin syringe (~12 units for 300 mcg).
Store between uses
Keep the reconstituted vial refrigerated and use within its stable window.
Handling & storage
- A 5 mg vial with 2 mL bacteriostatic water gives 2500 mcg/mL, so 250 mcg is about 0.1 mL (10 units).
- Reconstitute gently; store the solution refrigerated and protect from light.
- Community protocols often time a dose around training, though this is not validated.
- Investigational/preclinical - human dosing is not established.
PEG-MGF dosing FAQ
Is there an established PEG-MGF dose?
No. It is investigational, and the commonly cited ~200-400 mcg per dose comes from research-community references rather than human trials.
How is PEG-MGF different from regular MGF for dosing?
The PEG chain is meant to slow clearance so it can be dosed far less often - community references use 1-3 times weekly, versus native MGF being cleared within minutes.
How do I measure ~250 mcg?
From a 5 mg vial in 2 mL water (2500 mcg/mL), 250 mcg is 0.1 mL - about 10 units on a U-100 syringe.
How often is it dosed?
Community references cite 1-3 times weekly, sometimes timed around training. This frequency is not clinically established.
