PNC-27Anabolic & IGF
MGF (Mechano Growth Factor)- Summary
- PNC-27 is a synthetic peptide derived from the p53 tumor suppressor protein, containing both an HDM2-binding domain and a transmembrane penetratin sequence. It selectively kills cancer cells by binding MDM2/HDM2 overexpressed on the plasma membrane of malignant cells, inducing membranolysis without harming normal cells.
- MGF (Mechano Growth Factor) is a splice variant of IGF-1 that is locally produced in muscle tissue in response to mechanical damage from exercise. It activates muscle satellite cells (stem cells) to proliferate and repair damaged fibers, making it specifically targeted at exercise-induced hypertrophy.
- Half-Life
- Not well established; estimated minutes to hours
- Native MGF: minutes. PEG-MGF: ~3 days
- Admin Route
- Intravenous (research), Intraperitoneal (research)

- 200–400 mcg
- Frequency
- Not established for human use
- 1–2 times per week
- Key Benefits
- Selective cytotoxicity against cancer cells overexpressing HDM2/MDM2
- Spares normal cells lacking surface HDM2 expression
- Membranolytic mechanism bypasses intracellular resistance pathways
- Demonstrated activity against breast, pancreatic, leukemia, and melanoma cell lines
- Potential for combination with conventional chemotherapy
- Novel non-genotoxic anticancer mechanism
- Activates muscle satellite cells for repair and growth
- Accelerates recovery from muscle damage
- Synergistic with IGF-1 LR3 (different mechanisms)
- Promotes muscle hypertrophy specifically at exercised muscles
- Faster recovery between training sessions
- Potential for injury repair in connective tissue
- Side Effects
- Limited human clinical data; largely in vitro and animal studies
- Potential immunogenic reactions (foreign peptide)
- Systemic toxicity at high doses not well characterized
- Unknown interactions with current chemotherapy agents
- Muscle soreness (satellite cell activation)
- Injection site irritation
- Hypoglycemia risk (modest, less than IGF-1 LR3)
