A modified 29-residue peptide without the drug affinity complex. The No DAC qualifier distinguishes this reference from DAC-conjugated material.
Read the research guideIGF-1 LR3
An engineered IGF-I analog whose modifications change more than its name. Long Arg3 IGF-I is commonly abbreviated IGF-1 LR3.
Read the research guideIpamorelin
Five residues, including several deliberately unusual building blocks. Ipamorelin was developed as a peptide growth-hormone secretagogue.
Read the research guideMelanotan-1
A modified alpha-MSH analog with a linear reference chain. Melanotan-1 is also called afamelanotide or NDP-alpha-MSH in scientific records.
Read the research guideMelanotan-2
A cyclic member of the melanocortin-peptide family. Melanotan-2 combines a short chain with a side-chain connection that closes part of it into a ring.
Read the research guidePT-141
A cyclic melanocortin analog also known as bremelanotide. Its relationship to Melanotan-2 makes terminal chemistry especially important when identifying the molecule.
Read the research guideRT
A closer look at the 39-residue reference chain and three receptor targets.

The first 29 residues of a growth-hormone-releasing hormone reference, with an amidated ending. Sermorelin is commonly identified as GHRH(1–29)-NH₂.
Read the research guideSMA
One modified peptide with one receptor target. SMA, originally NN9535, was designed through targeted peptide modifications intended to alter enzymatic stability and albumin association.
Read the research guideTesamorelin
A modified 44-residue GHRH-family peptide. Tesamorelin, also called TH9507, was designed with a modified N-terminus to change susceptibility to enzymatic degradation.
Read the research guideTRZ
One modified peptide with two receptor targets. TRZ, originally LY3298176, was developed as a dual agonist: two receptor activities combined in one molecule.

AOD-9604
A fragment-based design with a compact disulfide loop. AOD-9604 is a synthetic peptide related to the C-terminal region of growth hormone, rather than the complete hormone.
Read the research guideARA-290
A short peptide inspired by a surface of a much larger protein. ARA-290, also called cibinetide, was developed from structural features of erythropoietin (EPO).
Read the research guideBPC-157
Fifteen amino acids in a distinct synthetic sequence. BPC-157 is a single peptide, separate from the mixtures in which it may also appear.
Read the research guideKisspeptin-10
A short active region from the kisspeptin family. Kisspeptin-10 is studied as a ligand for the KISS1 receptor, also called GPR54.
Read the research guideKPV
Three letters that directly name three amino acids. KPV stands for lysine, proline and valine, a short sequence associated with the C-terminal region of alpha-MSH.
Read the research guidePE-22-28
A seven-residue fragment investigated in ion-channel research. PE-22-28 is related to spadin and studied in the context of TREK-1, a two-pore-domain potassium channel.
Read the research guideSelank
A tuftsin-derived sequence with a three-residue extension. Selank is a synthetic heptapeptide with the reference sequence Thr–Lys–Pro–Arg–Pro–Gly–Pro.
Read the research guideSemax
An ACTH-fragment-inspired peptide with a Pro–Gly–Pro extension. Semax combines two short sequence regions into a single seven-residue chain.
Read the research guideSNAP-8
A peptide name associated with acetyl octapeptide-3 in cosmetic-ingredient records. The name of a cosmetic ingredient and the specification of a research powder answer different questions.

DSIP
Nine residues in a peptide also known as emideltide. DSIP abbreviates the historical name delta sleep-inducing peptide.
Read the research guideEpithalon
Four amino acids in the sequence Ala–Glu–Asp–Gly. Epithalon is also spelled Epitalon in reference records.
Read the research guideGlutathione
A small peptide with an unusual linkage and a central role in redox chemistry. Reduced glutathione is commonly abbreviated GSH.
Read the research guideLL-37
A 37-residue chain from the cathelicidin precursor. LL identifies the two leucines at the beginning of the reference sequence.
Read the research guideMOTS-C
A 16-residue peptide that connects mitochondrial genetics with cellular signaling. MOTS-C was reported from a short open reading frame within mitochondrial 12S rRNA.
Read the research guidePinealon
A three-residue peptide explored in cellular stress models. Pinealon is the Glu–Asp–Arg sequence, often abbreviated EDR.
Read the research guideSS-31
A four-residue peptide studied at the mitochondrial membrane. SS-31 research focuses on interactions with cardiolipin and the behavior of cytochrome c.
Read the research guideTB-500
A thymosin-related research material, supplied here in its 43-amino-acid form. The TB-500 name also appears in analytical literature on much shorter fragments, so chain length is worth checking in every record.
Read the research guideThymosin Alpha-1
A 28-residue peptide identified through thymic-polypeptide research. Thymosin alpha-1 has its own sequence and research history, separate from beta thymosins.
Read the research guideVIP
