Featured research peptides
CJC-1295 + Ipamorelin 10mg (blend)
A blend of two secretagogues studied together for their complementary mechanisms. CJC-1295 is a synthetic analogue of growth-hormone-releasing hormone, based on a modified GRF(1-29) sequence whose substitutions resist enzymatic degradation. Ipamorelin is a selective pentapeptide agonist at the ghrelin receptor. Because the two act on separate receptor pathways, the pair appears frequently in endocrine research examining pulsatile secretion. Supplied lyophilised. For laboratory research use only.
FOXO4 10mg
FOXO4-DRI is a retro-inverso peptide: built from D-amino acids in reversed sequence, which makes it resistant to the proteases that would degrade the natural form. It was designed to interfere with the FOXO4–p53 interaction, and is the reference compound in senolytic research concerned with the selective clearance of senescent cells. Supplied lyophilised. For laboratory research use only.
IGF-1 LR3 1mg
IGF-1 LR3 (Long R3) is an 83-amino-acid analogue of human insulin-like growth factor 1, modified by substituting arginine for glutamic acid at position 3 and adding a thirteen-residue N-terminal extension. Both changes reduce its affinity for IGF-binding proteins, which substantially extends its half-life relative to native IGF-1 and is why it is preferred for in-vitro work. Supplied lyophilised. Independently assayed by a third-party laboratory, named on this page; the certificate of analysis for this lot, with its measured purity and batch number, is published on this page. For laboratory research use only.
DSIP - 15mg
DSIP — delta sleep-inducing peptide — is a nonapeptide first isolated in 1977 from the cerebral venous blood of rabbits during induced slow-wave sleep, which is how it acquired its name. It crosses the blood-brain barrier readily for a peptide of its size, and appears in chronobiology and neuroendocrine research. Supplied lyophilised. For laboratory research use only.
GHK-Cu 50mg
GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine complexed with copper(II). The GHK sequence occurs naturally in human plasma, where its concentration declines with age, and it binds copper with high affinity — the property that makes it a subject of extracellular-matrix and collagen-remodelling research. It appears widely in dermatological and wound-model studies. Supplied lyophilised as the copper complex, which gives it a characteristic blue colour. Independently assayed by a third-party laboratory, named on this page; the certificate of analysis for this lot, with its measured purity and batch number, is published on this page. For laboratory research use only.
TB-500 10mg
TB-500 is a synthetic peptide corresponding to the active region of thymosin β4 — the short actin-binding sequence around residues 17–23, rather than the full 43-residue protein. Actin sequestration is the mechanism most cited in the cell-migration and tissue-repair literature in which it appears. Supplied lyophilised. Independently assayed by a third-party laboratory, named on this page; the certificate of analysis for this lot, with its measured purity and batch number, is published on this page. For laboratory research use only.
