GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, a sequence present in human plasma that binds copper with high affinity. In the PepXtide structural library the copper is
$59.99

KPV is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone, corresponding to residues 11 to 13 of alpha-MSH. At three residues it is small enough that the PepXtide structural library ren
$79.99 - $149.99

MOTS-c is a sixteen-residue peptide encoded in mitochondrial DNA rather than the nuclear genome, which is unusual enough to be the reason it is studied at all. It is modelled as an alpha helix in the

SS-31, also known as elamipretide, is a four-residue peptide with an alternating aromatic-cationic motif that concentrates at the inner mitochondrial membrane. Residue 2 is 2,6-dimethyltyrosine, model
$79.99 - $149.99

Tesamorelin is a stabilised analogue of human growth-hormone-releasing hormone, carrying all 44 residues of GHRH(1-44) with a trans-3-hexenoyl group attached to the N-terminal tyrosine. That acyl grou
$99.00 - $199.99

PepX-3 RT is a 39-residue lipopeptide studied as a triple agonist at the GLP-1, GIP and glucagon receptors. Three positions carry non-standard residues: alpha-aminoisobutyric acid at 2 and 20, and alp
$139.99

KLOW is a blend rather than a single compound: GHK-Cu, BPC-157, TB-500 and KPV supplied together in one vial. Because it is a mixture it has no single CAS number, molecular formula or molecular weight
$69.99 - $189.99

PepX-1 SM is a 31-residue lipopeptide analogue of GLP-1, studied as an agonist at the GLP-1 receptor. Position 2 carries alpha-aminoisobutyric acid in place of alanine, which is the substitution that
$129.99 - $149.99

PepX-2 TRZ is a 39-residue lipopeptide studied as a dual agonist at the GIP and GLP-1 receptors. It carries alpha-aminoisobutyric acid at positions 2 and 13, a C-terminal amide, and a C20 fatty diacid
$129.99

AOD-9604 is a 16-residue fragment corresponding to the C-terminal region of human growth hormone, residues 176 to 191, closed by a disulfide bridge between the two cysteines at positions 7 and 15. The

BPC/TB Stack is a blend rather than a single compound: BPC-157 and TB-500 supplied together in one vial. Because it is a mixture it has no single CAS number, molecular formula or molecular weight, and
$119.99

Glow is a blend rather than a single compound: GHK-Cu, BPC-157 and TB-500 supplied together in one vial. It is the same set as KLOW without the KPV. Because it is a mixture it has no single CAS number
$79.99

Dihexa is a small-molecule derivative of angiotensin IV rather than a peptide in the ordinary sense. Its structure is N-hexanoic-Tyr-Ile-(6) aminohexanoic amide: a Tyr-Ile core with a six-carbon acyl
$79.99

Sermorelin is the first 29 residues of growth hormone releasing hormone, ending in a C-terminal amide. That fragment is the shortest one still recognised at the GHRH receptor, which is why the analogu
$114.99 - $199.99

A long-acting analogue of the pancreatic peptide hormone amylin carrying a fatty diacid lipidation on the chain. Lipidated analogues sit outside the PepXtide structural library, which models plain pep
$139.99

A tetrasubstituted analogue of growth hormone releasing factor GRF(1-29) fitted with the Drug Affinity Complex, a maleimidopropionic acid linker on a C-terminal lysine. The linker chemistry places it
$99.99

Also known as Mod GRF 1-29: the 29-residue fragment of growth hormone releasing factor carrying four substitutions (D-Ala at 2, Gln at 8, Ala at 15, Leu at 27) with an amidated C-terminus. Drawn in th
