The complex has a characteristic blue-purple color and a molecular weight of ~401.9 Da.[1] GHK-Cu functions as a safe copper delivery vehicle by "redox silencing" the Cu(II) ion preventing Fenton reaction toxicity that free copper would cause

Poly lactic-co-glycolic acid (PLGA) as biodegradable controlled drug delivery carrier

Copper Peptide (GHK-Cu) is a biomimetic tripeptide complexed with copper ions, recognized for its role in cosmetic formulations targeting skin revitalization and improved appearance

Most of the evidence suggests the amount reaching the right target is quite small, so you have to go for really active agents. A Trojan horse method, which links therapeutic agents to molecules that normally transit the barrier, is championed by Pardridge

To illustrate, a 2015 study showed that rats fed a collagen peptide absorbed more than 63% of the collagen, whereas other orally administered peptides have exhibited bioavailability rates as low as 1-2%.12 13 BPC-157 is an exception, too it remains stable in gastric juice for more than 24 hours, allowing it time to pass through the gastrointestinal walls15 but its often used in conjunction with the not-so-orally-bioavailable TB4
