PE-22-28 vs PEG-MGF
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
PE-22-28
PE-22-28 is a synthetic peptide fragment derived from research on the SAMP8 mouse model of accelerated aging. It has shown potential for enhancing memory and reducing cognitive decline.
Full details →PEG-MGF
PEG-MGF (PEGylated Mechano Growth Factor) is a variant of IGF-1 that is produced in response to muscle damage. PEGylation extends its half-life from minutes to several hours, making it practical for use.
Full details →Side-by-Side Comparison
| Aspect | PE-22-28 | PEG-MGF |
|---|---|---|
| Mechanism | Derived from the protein that is deficient in SAMP8 mice. May work by inhibiting protein phosphatase 2A methylesterase, thereby affecting memory-related signaling pathways. | Activates muscle satellite cells (stem cells) and promotes their fusion to existing muscle fibers for repair and growth. MGF is produced naturally in response to mechanical stress on muscles. |
| Typical Dosage | Research protocols vary. Intranasal dosing has been studied at various concentrations. Optimal human dosing not established. | Research protocols typically use 200-400mcg injected into targeted muscle groups 2-3 times weekly, usually post-workout. |
| Administration | Intranasal administration preferred for CNS delivery. Research compound with limited human use data. | Intramuscular injection, ideally into muscles trained that day. Best administered post-workout when satellite cell activation is relevant. |
| Side Effects | Very limited human data. Primarily studied in animal models for safety and efficacy. | Injection site soreness, potential hypoglycemia, and localized swelling. Generally well-tolerated. |
