Research Peptide Profiles
BPC-157
Injury, Repair & Recovery
BPC-157 is a healing peptide originally derived from a protein found in the human stomach lining. It's best known for potentially speeding up recovery from injuries to muscles, tendons, ligaments, and the gut. It may work by calming inflammation at injury sites, boosting blood flow to damaged tissue, and helping new blood vessels form — all of which support faster healing. It's especially popular for gut health, where it may help repair the stomach lining and protect against ulcers and irritation. BPC-157 may also support wound healing by improving collagen production, and some research suggests it could help with nerve-related pain by reducing inflammation. It's one of the most widely studied and commonly used peptides in the research community.
TB-500 (Thymosin Beta-4 Fragment)
Injury, Repair & Recovery
TB-500 is a recovery peptide that may help heal wounds, reduce inflammation, and repair damaged tissue. It's commonly paired with BPC-157 for injury recovery protocols.
GHK (Tripeptide)
Injury, Repair & Recovery
GHK is a naturally occurring copper-binding peptide that may support skin repair, wound healing, and collagen production. It's the base peptide that GHK-Cu is derived from.
About the Directory
How the Research Peptides Directory Works
The PeptideWiki directory organizes research peptides into clear, evidence-based profiles covering mechanisms, dosing, safety, and research status. Browse by category, development stage, or peptide name to compare compounds across weight loss, recovery, growth hormone, cognition, longevity, and more.
Categories
Peptides are grouped by their primary research focus and biological activity, including metabolism, growth hormone signaling, tissue repair, cognition, inflammation, aesthetics, cellular health, sexual health, and endocrine function.
Development Stage
Shows how far a peptide has progressed in the research pipeline. Preclinical compounds are still in laboratory or animal models. Phase 2, 3, and 4 compounds have moved further through human research. Discontinued compounds are no longer being actively developed.
Regulatory Approval
Shows whether a peptide has been cleared by a health authority or is still limited to research. "Not Approved" means no clinical clearance. "Investigational" means still under study. "FDA Approved" means cleared in the United States for specific indications.
Compounding Status
Shows where a peptide sits in the FDA 503A and 503B compounding pathways. Cat 1 compounds are under enforcement discretion and are compoundable today. Cat 2 compounds have safety concerns flagged. Withdrawn, Not Compoundable, and Component of FDA-Approved Drug categories each reflect different regulatory histories.
