Temperature, moisture and light. Cold slows every chemical process; dryness removes the reactant most of them need; darkness matters for anything that absorbs visible light, which for this catalogue means GHK-Cu in particular.
A vial kept frozen, sealed and dark is in about the best condition available to it. Opening it repeatedly in humid air is the most common way that is undone, because lyophilised powder takes up atmospheric moisture readily.
Hydrolysis of the peptide backbone becomes possible. Deamidation of asparagine and glutamine proceeds. Methionine and cysteine can oxidise. For a folded protein, unfolding and aggregation become the dominant concern.
Bacteriostatic water adds 0.9% benzyl alcohol, which inhibits bacterial growth and is what makes multiple entries into a vial reasonable. It does nothing about any of the chemical routes above.
A usable figure for reconstituted shelf life depends on the compound, the concentration, the diluent, the storage temperature and what the material is being used for. A supplier stating one flat number for everything would be making it up.
What can be stated is what was supplied: identity and purity for the lot, documented on a certificate, with the material shipped dry and cold so that the clock has not started before it arrives.
