Recovery & Repair

A natural germ-killing peptide your own body makes to fight infection and help heal skin, tested in real wound-healing trials that have so far been promising but inconclusive.

Grade B · Human trials exist but are incomplete.

An experimental gut-barrier peptide that aimed to be the first drug for coeliac disease, but failed its large Phase 3 trial and is approved nowhere.

Grade B · Human trials exist but are incomplete.

A natural body hormone that relaxes blood vessels and airways and dampens inflammation. Its lab-made version was tested in serious lung disease but failed to prove it works.

Grade B · Human trials exist but are incomplete.

A lab-made 11-amino-acid offcut of the hormone EPO, engineered to keep its tissue-repair and anti-inflammatory effects while losing the red-blood-cell boost — with promising but unfinished human trials in nerve damage.

Grade C · Some human data, far from settled.

The whole natural repair peptide that TB-500 is cut from: it has been through real human trials as eye drops, a wound gel and a heart drug, with good safety but mostly disappointing results, and it has never been tested for the sports-injury use it is sold for.

Grade C · Some human data, far from settled.

A lab-made peptide based on a fragment of a protein found in stomach fluid, widely studied in animals for tissue repair but essentially untested in humans.

Grade D · No meaningful human evidence yet.

A three-amino-acid fragment of alpha-MSH that suppresses inflammation in cell and animal studies but has never been tested in humans.

Grade D · No meaningful human evidence yet.

A lab-made fragment of a natural repair protein, sold as a research chemical for healing and recovery on the strength of animal studies, with no proven human benefit.

Grade D · No meaningful human evidence yet.
