FGL 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.
FGL
FGL (FG Loop) is a synthetic peptide that mimics the neural cell adhesion molecule (NCAM) FG loop region. It promotes neuroplasticity and has shown cognitive-enhancing effects in research.

| Aspect | FGL | BPC-157 & TB-500 (Wolverine Stack) |
|---|---|---|
| Mechanism | Binds to FGFR1 (fibroblast growth factor receptor 1) to activate downstream signaling cascades that promote neurite outgrowth, synaptic plasticity, and neuronal survival. | 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 have used subcutaneous doses ranging from 1-10mg. Intranasal administration also studied. Optimal 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 | Subcutaneous injection or intranasal administration. Research compound with limited human dosing 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 | Limited human data available. Animal studies show good tolerability. | Generally well-tolerated. May include mild nausea, temporary fatigue, headache, or localized irritation at injection sites. |
