- The saline restriction is the critical difference. If you reconstitute multiple peptides in the same session, keep the saline away from GHK-Cu vials entirely. Label your solvents clearly. A single accidental saline reconstitution renders the entire vial of GHK-Cu less effective.
- The blue-green color is unique to GHK-Cu and acts as a built-in quality indicator. No other common peptide provides this visual confirmation that the active compound is intact. Use it. Check the color every time you draw a dose.
- For users running a GHK-Cu + BPC-157 + TB-500 blend, the blend vial is pre-mixed and the solvent choice is already accounted for. Reconstitute the blend with bacteriostatic water per the blend dosage guide.
