Hobson, B

longer under freezer storage when documentation supports it Lyophilized powder for long-term storage -20 C freezer, dry container, minimal temperature cycling Best option for long-term retention before reconstitution Reconstituted BPC-157 2-8 C refrigerator, protected from light About 28 days as a conservative default unless supplier data says otherwise Unknown temperature history Not reliable Discard or replace rather than guessing Lyophilized BPC-157 Lasts Longer Than Reconstituted BPC-157 Most research BPC-157 is supplied as lyophilized powder

GHK-Cu is supplied as a lyophilised powder with the characteristic blue colour of copper-peptide complexes and is the form of GHK most commonly used in skin-biology and cell-culture research literature
