Follistatin 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.
Follistatin
Follistatin is a glycoprotein that inhibits myostatin, the protein responsible for limiting muscle growth. By blocking myostatin, follistatin can theoretically allow for increased muscle development beyond natural limits.

Known as the 'Wolverine Stack,' this popular combination pairs two powerful healing peptides. BPC-157 and TB-500 work synergistically to promote tissue repair, reduce inflammation, and accelerate recovery from injuries.

| Aspect | Follistatin | BPC-157 & TB-500 (Wolverine Stack) |
|---|---|---|
| Mechanism | Binds to and neutralizes myostatin and activin, both of which are negative regulators of muscle mass. This removes the natural brake on muscle growth, allowing for enhanced hypertrophy. | 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 typically use 100-300mcg daily, though optimal dosing is not well established. Gene therapy approaches have also been studied. | 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. Different isoforms exist (FS344, FS315) with varying properties. Requires careful sourcing due to complexity. | 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. Theoretical concerns about effects on other organs where activin signaling is important. | Generally well-tolerated. May include mild nausea, temporary fatigue, headache, or localized irritation at injection sites. |
