Storing The Long Shot: Best Practices
Recommended Laboratory Storage Conditions — The Long Shot (5 vials)
Lyophilized Powder: Store all five vials at -20°C for long-term stability, protected from light and moisture. The GHK-Cu vial has a characteristic pale-blue tint from the copper complex.
Reconstituted Solution: Store aliquots at -80°C for extended periods; refrigerated (2–8°C) solutions should be used promptly. Reconstitute by gentle swirling — do not vortex or shake aggressively.
NAD+ Handling: NAD+ in solution is sensitive to alkaline pH and elevated temperature. Prepare working solutions fresh and avoid repeated freeze-thaw cycles.
GHK-Cu Incompatibilities: Do not co-formulate with EDTA, carnosine, Vitamin C, or other strong chelators — these strip Cu(II) from the complex.
Separate Handling: Each vial contains a single compound. Reconstitute and store each independently; there is no published stability data for pre-mixing these three in one solution.
Handling: Allow vials to reach room temperature before opening to prevent condensation onto the lyophilized cake. Use standard aseptic technique. Discard any solution that appears cloudy or contains particulate matter.
“Preclinical Research Summary (Component-Level) No peer-reviewed study has evaluated this five-vial kit as a unit.”
