You're poking me with a sharp stick, trying to make me crawl farther and farther out on a limb!
The only two trials I'm aware of that directly tested copper peptides and topical minoxidil head-to-head (one was a human study, the other was in animals) only used 2% minoxidil, but they _appeared_ to show that the copper peptides were at least as effective as the minoxidil, so that would seem to put them in the same general neighborhood of effectiveness. However, if you push me by asking for a direct comparison with 5% minoxidil, then I obviously have to get more and more uncertain about such speculation.
Furthermore, I find myself in the strange and awkward position of having to defend Folligen itself, which I've always been somewhat dubious about over the years. My comments are actually for copper-peptides in general, not Folligen specifically.
