GHK-Cu solo vs. Stacked with BPC-157 for a slow-healing peroneal tendon, what would you actually run?

Question

Got a peroneal tendon that's been nagging me for like 4 months now. Not a tear, more like a chronic grumpy thing that flares up after longer runs and doesn't fully calm down between sessions. I've been doing all the usual PT stuff, eccentric loading, balance work, the boring stuff, and it's helping but slowly. Ran BPC-157 arginate oral on it earlier in the year and i'm pretty sure it moved the needle, but it stalled out around the 6 week mark and never quite got me to 100%. Now i'm wondering if adding GHK-Cu would push it over the edge or if that's just throwing more at a problem that mostly needs more time. For those who've used GHK-Cu specifically for tendon stuff, did you run it solo or stack it? And how long before you actually noticed a real change, not just the first week placebo window. Ngl i'm tempted to do another BPC round with GHK-Cu layered in but i don't wanna just shotgun compounds at it.

Peroneal tendons are slowww and grumpy by nature, so 4 months honestly doesn't surprise me. GHK-Cu is interesting because it's working on collagen synthesis and the tissue remodeling side, which is kinda different from what BPC does. So the mechanisms aren't really overlapping much imo. If BPC stalled, it might be because the tissue still needs help laying down organized collagen, not because BPC stopped working per se. I haven't used GHK-Cu solo for tendons so I can't speak to that, but for me the injectable route at 2mg daily seemed way more practical than topical for something that deep. Noticed anything around week 3-4 but to be fair could be placebo. Curious what your PT thinks about the timeline, because for peroneals I've heard most people need closer to 6 months before calling something chronic.

The collagen deposition angle makes sense to me. Tendons are basically parallel collagen cables and if the cross-linking is still janky, BPC can reduce inflammation and improve blood flow all day and the tissue still wont remodel right. GHK-Cu is kind of targeting that downstream part of the process. Never ran it solo for tendon work either but I did use it for a gnarly ankle sprain that was taking forever and I think it shaved a few weeks off what would have been a slow recovery. Used the injectable route too, 2mg daily into the tissue around the site, the topical just seemed like it wouldnt get deep enough for something like peroneal tendon work. You could probably rotate them honestly, BPC in the morning and GHK-Cu at night, they are working on different pathways so overlap is minimal.
