Research peptides, verified to one standard.
Each batch third-party tested for identity and purity, with its certificate of analysis filed by batch number. Analog peptides, fragments, cofactors & conjugates.






Buy the ladder, not the vial.
Tiers apply per SKU, per order, at the listed quantity. The exact pack ladder for a compound is shown on its product page. One-time purchases only. This store does not offer subscriptions or auto-ship. For research use only. 18+.
Three structural classes.
Sorted by what each compound is, its molecular structure, not by outcome categories. Every listing is supplied for laboratory research use only.
Analog Peptides
A peptide whose sequence is a deliberate modification of a naturally occurring one, residues substituted, added, or chemically altered at defined positions.
Structurally related to a reference peptide, but not identical to it.
Peptide Fragments
A short, defined section of a longer native peptide or protein sequence, synthesised on its own rather than as part of the whole chain.
The sequence is native; the length is a subset.
Cofactors & Conjugates
Non-peptide molecules, and peptides bound to a non-peptide partner such as a metal ion or small molecule.
Defined by what the molecule is joined to, not by chain length.
