Injury, healing and recovery
Will this help me heal faster?
Where the peptide world is loudest and the studies in people are fewest. That gap is the reason this section exists. Every page says which side of it a compound sits on.
72 compounds studied for this · 24 with a completed trial of a hundred people or more · 15 with no study in people at all
What has actually been measured here
This page lists the compounds studied for injury, healing and recovery. These pages work the other way round. They take one goal at a time and list every compound by how many people it was measured in, most first. Each shows what the study found, and the trials that found nothing are counted.
Tendon, ligament and injury healing
Does it heal a tendon faster?
Joint and knee pain
Will it help my knees?
Pain
Does it reduce pain?
Wound and skin healing
Does it close a wound faster?
Inflammation
Does it bring inflammation down?

PeptideAnti-agingReading on this goal
Peptides for Longevity: What the Evidence Actually Shows in 2026
A full review of every peptide and related compound sold for aging: GLP-1 drugs, rapamycin, the growth hormone peptides, epitalon, thymalin, klotho, humanin, senolytics, SS-31, GHK-Cu, MOTS-c and FOXO4-DRI. What happened in people, what happened in animals and the legal status of each, in one table. Plain English.
Peptides for Joint Pain: BPC-157, TB-500, Lorecivivint, Pentosan and Collagen Peptides, Evidence Tiered
What studies in people say about joint pain treatments: hyaluronic acid shots (89 studies, tiny effect), lorecivivint (waiting on the FDA since January 2026 after two big studies failed on pain), collagen peptides (three small studies), pentosan polysulfate (a 538-person study reporting in 2027), and BPC-157 and TB-500, whose human records sit outside the joint entirely. Plain English.
Peptides for Gut Health: BPC-157, KPV and Larazotide Ranked by Human Evidence
Five peptides sold or studied for the gut, sorted by what has actually been tested in people: larazotide (a good mid-sized study, then a big study stopped in 2022 because it wasn't working), teduglutide (approved), BPC-157 (three small reports in people, none about the gut), KPV (never tested in people) and pentadeca arginate (no studies at all), plus what the July 2026 FDA panel votes did and did not decide. Plain English.

What happened when people used peptides for hair loss: copper peptide scalp injections in thousands of clinic patients, a GHK hair study in 45 men, what users report, and how that compares with minoxidil and finasteride. Plain English, every study linked.
What the number counts, exactly
The number on each card is how many sources on that compound’s page are studies in people. It is counted the same simple way for all 453 compounds. You can check any of it by opening the profile and reading the list of sources. That is the whole point of showing a number at all.
It counts what we cite. It does not claim how much research exists. A compound with three studies in people here may have thirty in print, and the honest thing to say is that we have read and listed three. It is also not a quality score. Three small, loose studies count the same as three careful ones. So the groups tell you how much was measured in people, and the profile page tells you how well.
