Origin and target
Where each one comes from, and what it binds
ARA-290
Origin. An 11-residue peptide derived from the helix B domain of erythropoietin.
Target. Described in the literature as a ligand of the innate repair receptor, a heteromer distinct from the classical EPO receptor.
Full referenceBPC-157
Origin. A synthetic 15-residue sequence corresponding to a partial fragment of a protein isolated from gastric juice.
Target. No single receptor has been established for it in the literature. It is characterized structurally rather than by a defined binding partner.

Handling
The same for both
Both ship as freeze-dried powder, both mix with bacteriostatic water the same way, and both are stored at minus 20 C out of the light until then. What differs is which breakdown route each sequence is prone to, and the stability guide shows how to read that from the amino acids.
