Research Peptide Profiles
VIP (Vasoactive Intestinal Peptide)
Immune & Inflammation
VIP (Vasoactive Intestinal Peptide) is a neuropeptide that may help regulate inflammation, improve gut function, and support immune balance. It's being studied for chronic inflammatory conditions and mold illness.
Thymosin Alpha-1
Immune & Inflammation
Thymosin Alpha-1 is an immune-boosting peptide that may strengthen your body's defense against infections and support overall immune function. It's approved in several countries for hepatitis treatment.
LL-37 (Cathelicidin)
Immune & Inflammation
LL-37 is a natural immune defense peptide that may help fight infections and support the body's ability to ward off bacteria, viruses, and fungi.
ARA-290 (Cibinetide)
Immune & Inflammation
ARA-290 is an anti-inflammatory peptide that may help relieve nerve pain and promote tissue repair without suppressing the immune system. It's being studied for diabetic neuropathy and sarcoidosis.
KPV
Immune & Inflammation
KPV is an anti-inflammatory peptide that may help calm gut inflammation and support digestive health. It's a small fragment of a larger hormone involved in immune regulation.
Thymalin
Immune & Inflammation
Thymalin is an immune peptide derived from the thymus gland that may help restore immune function, especially in older adults. It's been studied for longevity and immune system rejuvenation.
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.
