PE-22-28 vs BPC-157 & TB-500 (Wolverine Stack)
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.

| Aspect | PE-22-28 | BPC-157 & TB-500 (Wolverine Stack) |
|---|---|---|
| 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. | BPC-157 upregulates growth factor expression and promotes angiogenesis, while TB-500 promotes cell migration and differentiation through actin regulation. Together, they enhance wound healing, reduce scar tissue formation, and support musculoskeletal recovery through complementary pathways. |
| Typical Dosage | Research protocols vary. Intranasal dosing has been studied at various concentrations. Optimal human dosing not established. | Typical research protocols: BPC-157 at 250-500mcg daily combined with TB-500 at 2-2.5mg twice weekly during loading phase, then 2mg every 2 weeks for maintenance. |
| Administration | Intranasal administration preferred for CNS delivery. Research compound with limited human use data. | Both peptides administered via subcutaneous injection. Some protocols suggest injecting near injury sites for localized effects. Can be injected separately or as a pre-mixed blend. |
| Side Effects | Very limited human data. Primarily studied in animal models for safety and efficacy. | Generally well-tolerated. May include mild nausea, temporary fatigue, headache, or localized irritation at injection sites. |
