What LL-37 is used for

  • Cathelicidin antimicrobial peptide — innate-immune research
  • Studied for infection and chronic inflammation

How it's typically used

Research range: ~0.1 mg subcutaneous daily, short courses.

What to watch for

  • Can be pro-inflammatory at higher doses — biphasic effects
  • Very limited human safety data
  • Not FDA-approved; injection-site reactions reported

About Healing & recovery

What they are
Repair peptides — short amino-acid chains studied for soft-tissue, tendon, and gut-lining healing. Almost all the evidence is animal or preclinical; human trials are scarce.
How they're run
Reconstituted from a lyophilised (freeze-dried) powder and injected subcutaneously, usually daily, in blocks of 4–6 weeks around a specific injury.
What to watch
None are approved drugs, so purity depends entirely on the source. Effects are gradual — judge a block by whether the injury measurably improved, not by how you feel on day 3.

Doses reflect what is commonly reported in research literature; they are not recommendations. Many compounds listed are experimental, not approved for human use, and/or controlled substances that are illegal to possess without a prescription in many countries.
