MOTS-c vs MGF (Mechano Growth Factor)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
MOTS-c
MOTS-c (Mitochondrial Open Reading Frame of the Twelve S rRNA type-c) is a mitochondrial-derived peptide that plays a key role in metabolic regulation and has emerged as a significant longevity research target.
Full details →MGF (Mechano Growth Factor)
MGF (Mechano Growth Factor) is a splice variant of IGF-1 that is produced locally in muscle tissue in response to mechanical stress. The non-PEGylated form has a very short half-life.

| Aspect | MOTS-c | MGF (Mechano Growth Factor) |
|---|---|---|
| Mechanism | Activates AMPK pathway, enhances glucose uptake in skeletal muscle, improves insulin sensitivity, and regulates mitochondrial function. Acts as a metabolic hormone affecting whole-body energy homeostasis. | Activates muscle satellite cells (stem cells) and promotes their proliferation without differentiation, priming them for fusion with existing muscle fibers during repair and growth. |
| Typical Dosage | Research protocols typically use 5-10mg administered subcutaneously several times per week. Optimal dosing not yet established. | Due to extremely short half-life (minutes), typical protocols use 100-200mcg injected directly into target muscles immediately post-workout. |
| Administration | Subcutaneous injection. Often combined with exercise protocols as it enhances exercise capacity and metabolic adaptation. | Intramuscular injection into trained muscles within minutes of workout completion. Must be used immediately after reconstitution due to instability. |
| Side Effects | Limited human data. Animal studies show good tolerability. May affect energy levels and exercise performance. | Injection site soreness, potential hypoglycemia, localized swelling. Short half-life limits systemic effects. |
