Research Peptide Profiles
Selank
Cognition, Mood & Neuroprotection
Selank is a calming peptide that may help reduce anxiety and improve mood without causing drowsiness. It's available as a nasal spray and has anti-anxiety effects similar to benzodiazepines, but without the sedation.
Epitalon (Epithalon)
Longevity & Cellular Health
Epitalon is an anti-aging peptide that may help slow cellular aging by activating telomerase, the enzyme that protects your DNA. It's one of the most studied longevity peptides.
Ipamorelin
Growth Hormone / IGF-1 Axis
Ipamorelin is a gentle growth hormone-releasing peptide that may improve sleep, recovery, and body composition with fewer side effects than stronger alternatives. It's considered one of the safest GH peptides.
Dihexa
Cognition, Mood & Neuroprotection
Dihexa is a potent nootropic peptide that may dramatically enhance memory and cognitive function. It's one of the most powerful brain-boosting compounds studied, but long-term safety data is limited.
Liraglutide
Metabolic & Weight Loss
Liraglutide is an FDA-approved GLP-1 weight loss and diabetes drug (brand names Saxenda and Victoza) that helps reduce appetite and control blood sugar with a daily injection.
MOTS-c
Longevity & Cellular Health
MOTS-c is a mitochondrial peptide that may boost metabolism and mimic some of the benefits of exercise. It's being studied for its potential to improve energy, blood sugar control, and fat burning.
Cerebrolysin
Cognition, Mood & Neuroprotection
Cerebrolysin is a brain peptide mixture that may support brain recovery after stroke, traumatic brain injury, or dementia. It contains natural nerve growth factors that help repair brain cells.
DSIP (Delta Sleep Inducing Peptide)
Cognition, Mood & Neuroprotection
DSIP (Delta Sleep-Inducing Peptide) is a sleep peptide that may help improve sleep quality and regulate sleep-wake cycles. It's being studied for insomnia and stress-related sleep issues.
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.
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.
GHRP-6
Growth Hormone / IGF-1 Axis
GHRP-6 is a growth hormone-releasing peptide that boosts your body's natural GH production and stimulates appetite. It's commonly used for muscle growth, recovery, and by those looking to increase calorie intake.
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.
SS-31 (Elamipretide)
Longevity & Cellular Health
SS-31 (Elamipretide) is a mitochondrial peptide that may protect and restore cellular energy production. It's being studied for age-related diseases, heart failure, and conditions caused by mitochondrial dysfunction.
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.
Melanotan 1 (Afamelanotide)
Skin, Hair & Aesthetics
Melanotan 1 (Afamelanotide) is a tanning peptide that may darken skin by stimulating melanin production. Unlike Melanotan II, it's FDA-approved under the brand Scenesse for a rare sun sensitivity disorder.
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.
