Research Peptide Profiles
Oxytocin
Hormones & Endocrine (Non-GH)
Oxytocin is the 'bonding hormone' peptide that plays a role in social connection, trust, and emotional well-being. It's naturally released during hugging, childbirth, and breastfeeding.
Kisspeptin-10
Hormones & Endocrine (Non-GH)
Kisspeptin is a hormone-signaling peptide that plays a key role in fertility and reproductive health. It triggers the release of hormones needed for ovulation and testosterone production.
Gonadorelin (GnRH)
Hormones & Endocrine (Non-GH)
Gonadorelin is a fertility and hormone peptide that triggers the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). It's used clinically to test pituitary function and support fertility treatments.
ACTH (Cosyntropin)
Hormones & Endocrine (Non-GH)
ACTH (Cosyntropin) is a diagnostic peptide used in medical settings to test whether your adrenal glands are working properly. It stimulates cortisol production and is primarily a clinical tool, not a performance peptide.
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 Withdrawn, Not Compoundable, and Component of FDA-Approved Drug categories each reflect different regulatory histories.
