Semaglutide

Metabolic & Weight Loss

Semaglutide is a GLP-1 weight loss drug (brand names Wegovy and Ozempic) that helps reduce appetite and control blood sugar. It's FDA-approved and is one of the most prescribed obesity medications worldwide.

Retatrutide

Metabolic & Weight Loss

Retatrutide is an investigational triple-action weight loss peptide that targets three metabolic pathways at once. In clinical trials, it's produced the strongest weight loss results ever seen from a drug — nearly 29% body weight reduction.

Tirzepatide

Metabolic & Weight Loss

Tirzepatide is a dual-action weight loss drug (brand names Zepbound and Mounjaro) that targets two hormone receptors to reduce appetite and improve blood sugar. It's FDA-approved and delivers stronger weight loss than semaglutide.

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.

5-Amino-1MQ

Metabolic & Weight Loss

5-Amino-1MQ is a small molecule that may boost metabolism and promote fat burning by blocking an enzyme called NNMT. It's being studied as a potential treatment for obesity and metabolic disorders.

HGH Fragment 176-191

Metabolic & Weight Loss

HGH Fragment 176-191 is a fat-burning peptide derived from human growth hormone that targets body fat without the other effects of full HGH. It's essentially the fat-loss portion of growth hormone isolated on its own.

AOD-9604

Metabolic & Weight Loss

AOD-9604 is a fat-burning peptide derived from human growth hormone that may help reduce body fat without affecting blood sugar or muscle mass. It targets fat cells specifically.

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.
