Kisspeptin names KISS1-derived peptides; kisspeptin-10 is YNWNSFGLRF-NH2. Sequence, mass, HPLC behaviour and how to check what is in a vial.

MOTS-c is the 16-residue mitochondrially encoded peptide MRWQEMGYIFYPRKLR. Sequence, mass, HPLC behaviour and how to verify a vial.

ARA-290 (cibinetide) is the 11-residue pyroglutamate peptide pEQLERALNSS. Sequence, mass, HPLC behaviour and how to verify a vial.

Products named for receptor systems rather than brand names are labelled that way deliberately. How to read those names, and why the convention exists.

Selank is the heptapeptide Thr-Lys-Pro-Arg-Pro-Gly-Pro: tuftsin plus Pro-Gly-Pro. Sequence, mass, and why three prolines broaden the peak.

FOXO4-DRI, also sold as Proxofim, is a 46-residue all-D retro-inverso peptide of about 5,358 g/mol. What that means and why it analyses oddly.

Gonadorelin is synthetic GnRH: a ten-residue peptide with a pyroglutamate N-terminus and a C-terminal amide. Sequence, mass and verification.

Cardiogen is the trade designation for the tetrapeptide Ala-Glu-Asp-Arg (AEDR). Sequence, mass, chromatographic behaviour and verification.

Cortagen is the trade designation for the tetrapeptide Ala-Glu-Asp-Pro (AEDP). Sequence, mass, why the proline matters, and how to verify it.

Pinealon is the trade designation for the tripeptide Glu-Asp-Arg (EDR). Sequence, mass, what the arginine does to HPLC, and how to verify it.
