every study conducted on ghk-cu has either been a topical application or injected locally into wounds at very high doses of around 2-20 mg/kg, so about 160 mg for the average male, ghk-cu has a half life of 6-24 hours in local tissue, but is rapidly degraded in plasma leaving it with a half life of only 0.5-2 hours, there is quite literally no reason the measly 2 mg the average person is injecting into their stomach would have any benefits in facial collagen
the only way to reap the benefits of ghk-cu is to use a topically applied solution after microneedling
