What are peptides?
A peptide is a short chain of amino acids — typically 2 to 50 — linked by peptide bonds. They sit between individual amino acids and full proteins in size, and many function as signalling molecules in the body. Research peptides are synthetic versions of these chains, studied in vitro for effects on healing, growth hormone release, metabolism, and cognition.
How many peptides are on this list?
This database indexes 72 research compounds across 10 categories: recovery & healing, muscle & growth, fat loss & metabolic, cognition & mood, sleep, longevity, skin & hair, immune & gut, libido & hormones, and Khavinson bioregulators. It includes true peptides plus clearly-labelled peptide-adjacent compounds (like 5-Amino-1MQ and NAD+) that are commonly grouped with them.
What are the most popular research peptides?
The most-studied and most-searched are BPC-157 (tissue and gut repair), TB-500 (systemic recovery), GHK-Cu (skin and collagen), semaglutide and tirzepatide (GLP-1 metabolic), and CJC-1295 + ipamorelin (growth hormone axis). Each is indexed above with its mechanism and research context.
What are the best-studied peptides for healing and recovery?
BPC-157 and TB-500 are the most referenced healing peptides in the literature — BPC-157 for gut lining, tendon, and ligament repair; TB-500 for cell migration and wound healing. They’re frequently studied together as the “Wolverine Stack.” GHK-Cu, KPV, and ARA-290 also appear frequently in recovery research.
What peptides are studied for muscle growth?
The main categories are growth hormone secretagogues (ipamorelin, CJC-1295, tesamorelin, hexarelin, GHRP-2/6), growth factors (IGF-1 LR3, IGF-1 DES, MGF, PEG-MGF), and myostatin-pathway compounds (follistatin-344, myostatin inhibitor). All are indexed under Muscle & Growth above.
What peptides are studied for fat loss?
The biggest group is the GLP-1 family (semaglutide, tirzepatide, retatrutide, orforglipron), plus tesamorelin (visceral fat), AOD-9604 and HGH Fragment 176-191 (lipolysis), MOTS-c, and metabolic compounds like 5-Amino-1MQ, SLU-PP-332, tesofensine, and BAM-15.
What are anti-aging or longevity peptides?
The core longevity compounds are epithalon (telomerase), FOXO4-DRI (senolytic), SS-31 (mitochondrial), NAD+, glutathione, thymosin alpha-1, and the Khavinson bioregulator family. Most longevity peptide evidence is preclinical or from Russian-language research.
