Patches and tongue strips instead of jabs?

Has anyone tried delivering peptides by routes other than swallowing them or injecting directly? A few companies appear to sell tongue strips and skin patches, and whether those actually work is what I cannot tell. For something like GHK-cu it would be a welcome change, since jabbing is not the nicest part of the routine.

Is there anyone with a side by side comparison, or even just their own anecdote?
