Evidence for inflammation

Each row is an outcome related to inflammation from a published study, strongest design first. Animal and cell results are labelled and are not human results. User reports are not counted as evidence here.

How strong is it?

Strongest evidence:Human RCT evidence, 4 of 4Microbial biotechnology 2021, PMID 34318587

A human randomized trial outweighs any number of animal studies. Animal and cell results show a mechanism worth testing, not that it works in people.

What inflammation means here

MedlinePlus defines inflammation as the body's way of protecting tissues and helping them heal from injury, infection or other disease.[3]

Studies closest to inflammation

In an alkali-burn animal model, a hydrogel carrying the TB500 sequence reduced inflammation and sped epithelial regeneration. No person was treated.[2]

In the one human study tied to an inflammatory skin disease, a recombinant full-length thymosin beta-4 gel (not TB-500) did better than ketoconazole lotion in seborrheic dermatitis.[1]

How much literature sits behind the goal

A dated PubMed count (query stored with the goal data, run 2026-10-02) found 78 human-only and 80 animal-only records for thymosin beta-4 or TB-500 terms combined with inflammation terms. Counts are of papers mentioning both, not of trials showing an effect.

Common questions

Does TB-500 help with inflammation?

The strongest study we summarise for inflammation is human rct evidence, across 2 studies with an outcome for inflammation. A trial result is not an approval; see the legal status.

Is TB-500 approved for inflammation?

No. TB-500 is not FDA approved for any use, including inflammation.

What is the best peptide for inflammation?

There is no single answer. Our inflammation overview compares each candidate by evidence grade and legal status rather than by popularity.

Is TB-500 anti-inflammatory?

A horse doping paper repeats the claim that TB-500 decreases inflammation but tested detection, not inflammation.[4]
