Nicknamed the nerve repair peptide. If you found it by searching for nerve pain, here is what the studies actually did and did not show.
The evidence rail
How to read this- Mechanistic: reached
- Cell research: reached
- Animal research: reached
- Human observational: reached
- Human clinical trial: reached, limited data
- Established clinical use: not reached
- Evidence
- Small controlled trialsRung 5 of 6, limited data. A designed trial in people with a comparison group. The bar for a real claim.
- Status
- Not FDA-approvedNot approved for use as a drug. Often sold as a research chemical.
- Topics
- Nerve + painInflammation
What has it been studied for?
- Neuropathic pain and inflammation in early human work
- Innate repair receptor signaling in preclinical models
What we know
- Small randomized, placebo-controlled trials exist, mostly in small fiber neuropathy. The nickname is more famous than the sample sizes
What we don’t
- Whether those small trials become a durable, replicated clinical story in larger ones
Bottom line
A nickname is not a proof.
Education only. Not medical advice. Not a protocol.
New sheets, the day they publish.
One email a week. The study type named, every time.
