Cosmetic & Skin Research

Three listings covering two compounds studied in dermal and matrix research: GHK-Cu, the copper-binding tripeptide, at the 50 mg loading; and SNAP-8, an eight-amino-acid analogue of acetyl hexapeptide-8. The heavier 100 mg GHK-Cu presentation is catalogued separately under repair research — the two are listed apart because they are ordered for different work, not because the material differs.
