MGF Dosing Protocol: 5 mg Vial — Post-Workout Dosing Schedule & Supplies
给药方案详解
以下方案内容整理自公开资料与临床文献，仅供研究参考，不构成医疗建议。
Quickstart highlights
Mechano Growth Factor (MGF) is an alternatively spliced isoform of the IGF-1 gene, expressed locally in mechanically stressed muscle tissue.
- Concentration: 1 mg/mL (5 mg vial + 5 mL bacteriostatic water).
- At 1 mg/mL: 100 µg = 10 units, 200 µg = 20 units per injection.
- Inject intramuscularly into target muscle within 30 minutes post-workout for satellite cell activation.
- One 5 mg vial provides 25 doses at 200 µg — approximately 8 weeks at 3x weekly dosing.
- Local injection only — MGF is not a systemic peptide; inject directly into the trained muscle.

| Week | Dose (µg) | Units | Frequency | Notes |
|---|---|---|---|---|
| 1-2 | 100 | 10 | 3x weekly post-workout | 100 µg — 10 units; inject into target muscle within 30 minutes post-exercise; one 5 mg vial provides 50 doses |
| 3-8 | 200 | 20 | 3x weekly post-workout | 200 µg — 20 units; standard maintenance dose; 25 doses per vial |

Reconstitution steps
- Draw 5 mL bacteriostatic water; inject slowly down the vial wall.
- Swirl gently until powder dissolves; do not shake.
- Final concentration: 1 mg/mL (1,000 µg/mL). At 1 mg/mL: 100 µg = 10 units, 200 µg = 20 units.
- Label with date; refrigerate at 2–8 °C. Use within 28 days.
Supplies needed
8-week plan
- 1 vial
- 24 syringes
- 5 mL bac water
- 24 alcohol swabs
Protocol overview & cycle notes
Activate satellite cells and accelerate post-exercise muscle repair through local intramuscular MGF injections timed to the post-workout repair window, using the 8-week MGF E-peptide protocol.
Cycle length: 8 weeks on.
Off-cycle: 4 weeks off after each 8-week cycle.
Storage & handling
Injection & tracking tips
- MGF is most effective when injected intramuscularly into the target muscle immediately post-workout (within 30 minutes); local injection concentrates the peptide at the site of mechanical stress-induced muscle damage.
- Rotate injection sites within the target muscle group; for bilateral muscles, inject both sides with half the dose each.
- MGF's primary biological effect is local (satellite cell activation) rather than systemic — unlike IGF-1 LR3 which has systemic metabolic effects.
Tracking
Logging helps you and your provider spot patterns and adjust dose or timing.
- Track delayed onset muscle soreness (DOMS) resolution speed weekly; MGF typically accelerates DOMS resolution.
- Measure target muscle circumference every 4 weeks.
- Log subjective training recovery score (0–10) after each workout.
