Feels like recovery faster but wanna confirm it’s not just placebo.
PEG-MGF Post-Leg Day
-
I’ve been pinning PEG-MGF post-leg day for a few months solid localized fullness and recovery boost. Way better when combined with IGF-1 LR3 the next morning though.
-
Tried it for 4 weeks. Honestly, I didn’t notice much. Maybe minor pump retention, but nothing dramatic unless diet and sleep were perfect.
-
If you’re doing it post-leg day, make sure to rotate injection sites. PEG-MGF can cause weird lumps if you hit the same quad repeatedly.
-
The PEG version has longer activity, so pinning post-workout makes sense. You don’t need to do it daily 2 3x per week after big sessions is plenty.
-
I like PEG-MGF right after heavy squats or deads. Feels like it keeps soreness down, but I stack it with BPC-157 so it’s hard to tell what’s doing what.
-
Good move post-leg day that’s when muscle damage is highest. I’d go 200–400mcg subq near the quads, then follow up with protein + carbs right after.
-
It shines when recovery is lagging. Not a miracle peptide, but it does help with muscle repair. Don’t expect visible hypertrophy unless everything else is dialed in.
-
I used PEG-MGF for a bulk and noticed better leg fullness, especially when alternating quads/glutes. Felt like recovery time dropped by a day or so.
