The same four peptides as KLOW at a completely different ratio, typically 5 mg TB-500, 5 mg BPC-157, 10 mg KPV and 5 mg GHK-Cu in a 25 mg vial. Copper peptide is 20% of the powder here against 62.5% in KLOW, which is roughly 0.8 mg of elemental copper per vial instead of 7.9 mg. No study has tested any four-peptide combination in any species.
