Practical combination approaches include topical serums containing both peptides, alternating injection sites (GHK-Cu subcutaneous, AHK-Cu scalp mesotherapy), or using GHK-Cu via microneedling with AHK-Cu in a topical serum applied after
Banks and Kastin reported that radiolabeled DSIP administered peripherally produced detectable DSIP-like immunoreactivity in brain tissue at levels above what non-specific leakage would predict, and that the modified analogue [D-Ala3]-DSIP entered brain at substantially higher levels than the parent compound after intracarotid administration (Banks & Kastin, 1981)
