Your goal
Healing injuries
Here's the honest truth: no peptide is a proven cure for healing injuries. A couple of real, approved medicines genuinely help specific damage — rebuilding broken bone, or aiding recovery after a stroke or head injury. But the peptides most people hear about for healing tendons and muscles are backed almost entirely by animal studies, not proof in people.
What actually works
2The strongest real evidence for this goal.
Teriparatide
ModerateA real, approved bone-building drug that doctors also use to help stubborn broken bones knit back together — the proof for fractures is thinner than for osteoporosis, but it's genuine medicine.
Cerebrolysin
ModerateHas the most real human trial evidence here for healing brain injury, helping some people recover after a stroke or serious head injury — though results are mixed and it's given by IV under a doctor.
Promising, still unproven
4Interesting early signals — not proven yet.
ARA-290
EmergingSmall but repeated human trials show it calms inflammation and helps damaged nerves regrow — promising for nerve injury, but still early.
BPC-157
EmergingThe famous "injury healing" peptide for tendons, muscles and joints — the animal data is strong and consistent, but human proof is just a few tiny studies.
TB-500
EmergingThe natural protein it copies healed wounds in real human trials, but the version sold online has never been properly tested and often isn't even what the label says.
Semax
EmergingUsed in Russia for decades to help people recover after a stroke, with real but small human evidence behind it.
Mostly hype — be skeptical
6Lots of buzz, little human proof. Tread carefully.
EPO
EarlyA proven medicine for anemia — but its use for healing brain injury failed its biggest trial, so it's not a healing drug despite the reputation.
MGF
EarlyInjected to speed muscle and injury recovery, but it has never been tested in a single human trial.
IGF-1 LR3
EarlyA lab-made growth hormone used as an animal research tool, with no proven human healing use.
Follistatin
EarlyA muscle-building protein studied only in animals — never tested as a treatment in people.
Dihexa
EarlyA brain-repair peptide that has only ever been tested in mice and rats.
AICAR
EarlyStudied mainly as a heart-protecting surgical drug and a metabolism research tool, not as a healing aid.
The honest bottom line
No peptide is a proven fix for injuries. The only real medicine here is for specific cases — bone with teriparatide, brain injury with cerebrolysin — while the popular tendon-and-muscle "healing" peptides like BPC-157 and TB-500 are promising but still unproven in people. A long tail of injectable "repair" peptides sold online (MGF, the IGF variants, follistatin and more) share the same story: good animal data, no human proof.
