How long should a GHK-Cu cycle be?

Studies in people do not establish a cycle length for GHK-Cu. The work in people on this peptide is on the skin, not an on and off calendar of shots. The cycle lengths passed around online for injected GHK-Cu are unverified habits. This site does not invent a schedule. Full detail at /cycling.
