MGF (Mechano Growth Factor) vs Octreotide
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
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.
Full details →Octreotide
Octreotide (Sandostatin) is a synthetic somatostatin analog FDA-approved for acromegaly, carcinoid tumors, and VIPomas. It inhibits growth hormone and various GI hormones.
Full details →Side-by-Side Comparison
| Aspect | MGF (Mechano Growth Factor) | Octreotide |
|---|---|---|
| Mechanism | Activates muscle satellite cells (stem cells) and promotes their proliferation without differentiation, priming them for fusion with existing muscle fibers during repair and growth. | Binds to somatostatin receptors (primarily SSTR2 and SSTR5) to inhibit GH, glucagon, insulin, and gastric secretions. Reduces blood flow to GI tract and inhibits tumor hormone secretion. |
| Typical Dosage | Due to extremely short half-life (minutes), typical protocols use 100-200mcg injected directly into target muscles immediately post-workout. | Varies by indication. Acromegaly: 50-100mcg three times daily initially, up to 500mcg TID. LAR (long-acting): 20-30mg IM every 4 weeks. |
| Administration | Intramuscular injection into trained muscles within minutes of workout completion. Must be used immediately after reconstitution due to instability. | Subcutaneous injection for immediate-release (between meals). Intramuscular for LAR depot form. Requires monitoring of gallbladder, glucose, and thyroid. |
| Side Effects | Injection site soreness, potential hypoglycemia, localized swelling. Short half-life limits systemic effects. | GI effects (diarrhea, nausea, abdominal pain), gallstones (up to 25% of long-term users), injection site reactions, and blood glucose changes. |
