Do peptides help with traumatic brain injury?
3 peptides are graded for traumatic brain injury on this page. The strongest grade is human RCT evidence, for cerebrolysin. Each one is weighed against the standard of care below, and the evidence table gives the grade and a note for every peptide.
What is the standard of care for traumatic brain injury?
Emergency stabilization and CT imaging; intensive care management of intracranial pressure, oxygenation, and blood pressure per Brain Trauma Foundation guidelines; surgery for mass lesions; seizure prophylaxis in the first week after severe TBI; then multidisciplinary rehabilitation. No neuroprotective drug has proven benefit in large trials.
Any peptide below should be judged against this baseline, not against doing nothing. Talk to a licensed provider before replacing or adding to an established treatment.
Which peptides have been studied for traumatic brain injury?
Ordered by strength of evidence for this use. Grades follow the methodology; each peptide page lists the individual studies.
| Peptide | Evidence for this use | Note |
|---|---|---|
| Cerebrolysin | Evidence: Human RCT evidence | A prospective meta-analysis of the two CAPTAIN trials (n = 185) found a small to medium benefit on a combined functional and neuropsychological score at 30 and 90 days; not FDA approved and not part of US TBI guidelines. [6] |
| TB-500 (thymosin beta-4) | Evidence: Animal-only evidence | Thymosin beta-4 improved functional recovery and brain remodeling in rats after TBI; no human TBI study. [7] |
| BPC-157 | Evidence: Animal-only evidence | Reduced injury severity in a mouse head trauma model; no human data. [8] |

Frequently asked questions
Which peptide has the strongest evidence for traumatic brain injury?
Cerebrolysin has the strongest evidence among the peptides graded here, at human RCT evidence. A prospective meta-analysis of the two CAPTAIN trials (n = 185) found a small to medium benefit on a combined functional and neuropsychological score at 30 and 90 days; not FDA approved and not part of US TBI guidelines. [6]
Is any peptide FDA approved for traumatic brain injury?
No. None of the peptides graded for traumatic brain injury is an FDA approved drug, so any use is outside an approved label and depends on the compounding and research status shown on each peptide page. [9]
Has any peptide been tested in a randomized trial for traumatic brain injury?
Yes, for cerebrolysin. Check each note for the population and endpoints: a randomized trial in a related group or on a surrogate marker is weaker than one on the outcome you care about. [6]
