Reasons it's not healing Poor blood flow to the area Lymphedema and lymphatic draining The area was so traumatized it's struggling to heal

Looking for advice on what would be the best thing to help finally heal this thing bc wound care has done nothing for the last year but debride no ointments besides occasionally silver nitrate and then more recently some type of grafts but they aren't made from his skin, but Insurance won't pay anymore for more grafts this year.

Something to promote collagen, skin regeneration, blood flow, lymphatic system support, is what I think would help.

I'm looking for suggestions/advice/info/reassurance on any peptides you all would recommend.

But also specifically on: ghk-cu BPC-157 Tb500

Also info on ROA? Topical, Injection, oral, nasal spray? I know some drugs are best taken certain ways so does it matter how one takes them? I'm just about to purchase some Tirzepatide and was going to get some of the tb500 with it, but it's powder and I'm thinking is that the best way to get it? should he be injecting or making caps with it?

I'm so new to this, but I see the potential for many applications. of course wound care Dr had no clue about any of it, though he wasn't against it. he said oh you can get it from food or gnc lol. Well guess what we aren't getting it from food! I'm just hoping to try anything to help him heal bc this has been going on for far too long.
