Longevity and skin research peptides
Copper peptides, mitochondrial-derived peptides and NAD+ precursors studied in cellular ageing, matrix remodelling and bioenergetics. The category spans genuinely different chemistry: GHK-Cu is a copper complex, MOTS-c and humanin are encoded in the mitochondrial genome, and NAD+ is a cofactor rather than a peptide at all.

What makes a peptide mitochondrial-derived?
It is encoded within the mitochondrial genome rather than the nuclear one. MOTS-c and humanin are the two best-described examples, and they come from different regions and signal through different pathways.
Why is GHK-Cu supplied as a copper complex?
The copper is part of the molecule as it is studied — the tripeptide binds Cu(II) with high affinity and the complex is what appears in the remodelling literature. Note it in a methods section, because copper is not inert in most assay systems.
Is NAD+ a peptide?
No. It is a dinucleotide cofactor. It is catalogued here because it appears in the same sirtuin and mitochondrial research as the peptides around it.
What do the certificates in this category show?
Every vial on this page carries a lot-matched certificate from an independent laboratory, published before the product was listed. Across the 8 lots currently listed here, purity by RP-HPLC at 214 nm runs from 99.75% to 99.9%, and identity is confirmed by LC-MS/MS or MALDI-MS. 1 product has no published certificate yet — ask support for the lot report before ordering Melanotan-2.

Common questions about longevity & skin
How is NAD+ handled differently?
It is more sensitive to moisture and to repeated temperature cycling than the peptides here. Keep it sealed and cold, and prepare working solutions fresh.
What is 5-Amino-1MQ doing in a peptide catalogue?
It is an NNMT inhibitor and a small molecule, not a peptide. It sits here because it shares the adipocyte and NAD+ salvage research context.
Are these for human use?
No. Sold for in-vitro laboratory research only.
Every product in this category is sold for in-vitro laboratory research only and is not for human or animal consumption, diagnostic or therapeutic use.
