BPC-157 & TB-500 (Wolverine Stack) vs NA-Selank Amidate
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
BPC-157 & TB-500 (Wolverine Stack)
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.
Full details →NA-Selank Amidate
NA-Selank Amidate (N-Acetyl Selank Amidate) is an enhanced version of Selank with improved stability and blood-brain barrier penetration. The modifications increase bioavailability and duration of cognitive and anxiolytic effects.

| Aspect | BPC-157 & TB-500 (Wolverine Stack) | NA-Selank Amidate |
|---|---|---|
| Mechanism | 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. | Same core mechanism as Selank - modulates BDNF, serotonin, and norepinephrine systems. The N-acetyl group improves membrane permeability while the amidate modification increases enzymatic stability. |
| Typical Dosage | 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. | Intranasal: 100-400mcg 1-3 times daily. Lower doses needed compared to standard Selank due to enhanced bioavailability. |
| Administration | 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. | Primarily intranasal administration. Can be used sublingually. More stable in solution than standard Selank. |
| Side Effects | Generally well-tolerated. May include mild nausea, temporary fatigue, headache, or localized irritation at injection sites. | Generally well-tolerated. Possible mild fatigue or nasal irritation. Less frequent dosing needed than standard Selank. |
