Quick answer · Community-reported standard
A 10 mg vial of PEG-MGF reconstituted with 2 mL of bacteriostatic water yields a concentration of 5.00 mg/mL. At that concentration, a 200 mcg dose of PEG-MGF equals 4 units on a U-100 insulin syringe (0.040 mL). PEG-MGF is typically administered every other day via subcutaneous.
PEG-MGF 10 mg reconstitution and dosage: 1 mL vs 2 mL bac water
For a 10 mg vial of PEG-MGF, bacteriostatic water volume is flexible. Less water means higher concentration and smaller injection volumes; more water means lower concentration and easier dose precision. Both options below are valid for a 10 mg vial.
| BAC water added | Concentration | Volume per 200 mcg dose | Draw on U-100 syringe (units) |
|---|---|---|---|
| 1 mL | 10.00 mg/mL | 0.020 mL | 2 units |
| 2 mL | 5.00 mg/mL | 0.040 mL | 4 units |
PEG-MGF dosage chart: per-injection to weekly total
Common PEG-MGF protocol doses centered on the 200 mcg baseline (research range 200 mcg–300 mcg), with weekly totals at every other day frequency.
| Dose level | Per injection | Frequency | Weekly total |
|---|---|---|---|
| Lower | 0.1 mg | Every other day | 0.35 mg |
| Baseline | 0.2 mg | Every other day | 0.7 mg |
| Higher | 0.3 mg | Every other day | 1.05 mg |
| Upper range | 0.4 mg | Every other day | 1.4 mg |
Weekly totals assume consistent every other day dosing. Adjust the calculator below for your specific vial size and dose.

Alternative PEG-MGF protocols
Beyond the default above, PEG-MGF is also reported in the following protocols. Use these as starting points and recalculate with the tool above.
Post-Workout IM Protocol
Community- Dose
- 200-400 mcg
- Frequency
- Post-workout, 2-3 times per week
- Duration
- 6-8 weeks
- Route
- Intramuscular
Injected into trained muscle groups 4-8 hours post-workout; some users split dose across multiple muscles
Beginner Protocol
Community- Dose
- 100-200 mcg
- Frequency
- 2-3 times per week
- Duration
- 6-8 weeks
- Route
- Subcutaneous
Conservative starting dose; allows assessment of tolerance before increasing
Recovery/Injury Protocol
Community- Dose
- 200-300 mcg
- Frequency
- Daily for 5-7 days, then 2-3 times weekly
- Duration
- 4-6 weeks
- Route
- Subcutaneous
Higher initial frequency for acute injury support, tapering to maintenance; combined with BPC-157 or TB-500
Muscle recovery research
Clinical- Dose
- 200 mcg
- Frequency
- 2-3 times per week
- Duration
- 4-6 weeks
Subcutaneous injection. Extended half-life allows less frequent dosing than native MGF. No human clinical validation exists for any protocol.
Post-exercise recovery research
Clinical- Dose
- 200-500 mcg
- Frequency
- 2-3 times per week (on non-training days)
- Duration
- 4-8 weeks
Some protocols suggest administration on non-training days to separate the PEG-MGF signal from the natural post-exercise MGF pulse. This timing rationale has not been validated.
PEG-MGF reconstitution & storage
Reconstitute lyophilized PEG-MGF powder with bacteriostatic water. For a typical 2 mg vial, add 1-2 mL of diluent. Gently swirl (do not shake) until dissolved. Solution should be clear and colorless. PEG-MGF is more stable than native MGF in reconstituted form. Use within 2-3 weeks when refrigerated.
Store lyophilized powder at -20C for long-term storage or 2-8C short-term. Reconstituted solution should be stored at 2-8C and used within 2-3 weeks. Do not freeze reconstituted solution. Protect from light. PEG-MGF is significantly more stable than native MGF due to PEG protection.
PEG-MGF dosing FAQ
How much bacteriostatic water should I add to a 10 mg vial of PEG-MGF?
The community standard is 2 mL of bacteriostatic water for a 10 mg PEG-MGF vial. That gives a concentration of 5.00 mg/mL, so a 200 mcg dose is 4 units on a U-100 insulin syringe. Adding 1 mL instead doubles the concentration to 10.00 mg/mL and halves the draw to 2 units. Less water = smaller injection volume but harder to measure precisely.
How many syringe units is a 200 mcg dose of PEG-MGF?
On a standard U-100 insulin syringe, a 200 mcg dose of PEG-MGF is 4 units when the 10 mg vial is reconstituted with 2 mL of bacteriostatic water (5.00 mg/mL). If you use 1 mL of bac water instead, draw 2 units (10.00 mg/mL).
What is the standard PEG-MGF dose?
Community-reported protocols for PEG-MGF typically use 200 mcg–300 mcg every other day via Subcutaneous. 200 mcg is a common starting dose. Injected within 30 minutes post-workout for systemic satellite cell activation; SubQ in abdominal area
How long does a vial of PEG-MGF last at 200 mcg every other day?
A 10 mg vial of PEG-MGF contains roughly 50 doses at 200 mcg per injection. At every other day dosing, that is approximately 100 days (about 14 weeks) of supply per vial. Reconstituted PEG-MGF should generally be used within 28 days when refrigerated.
Where do you inject PEG-MGF?
PEG-MGF is typically injected subcutaneous. Common sites reported in the literature and by users include: Subcutaneous (abdomen), Subcutaneous (thigh), Subcutaneous (upper arm), Subcutaneous (near target area, for localized protocols). Rotate sites with each injection to reduce localized irritation.
Can I use sterile water instead of bacteriostatic water for PEG-MGF?
Bacteriostatic water (containing 0.9% benzyl alcohol as a preservative) is strongly preferred for multi-dose vials like PEG-MGF because it inhibits microbial growth and lets a single vial be used over multiple weeks. Sterile water has no preservative and should generally be reserved for single-use preparations only.
