That is a heavy diagnosis. Your mother faces serious surgery. My father went through something similar and I would urge careful consideration because the operation can sometimes make things worse. The most important step is choosing a highly experienced surgeon since spinal work is complicated and should be a last resort. I doubt peptides will reverse her condition but a bpc/tb mix and possibly kpv might lower inflammation. Klow can help yet it has a lot of ghk-cu that may cause stinging so begin with a tiny dose and inject into the side of the quads or stomach where there is fat. I have no experience with ara290 though sources note it may aid nerve regeneration while her problem is mechanical pressure. I have dealt with lower back trouble for decades and use an inversion table which helps a great deal without needing to go fully upside down.
After months of pain and tingling my seventy-year-old mother finally had an MRI that showed spondylolysis, spondylolisthesis, severe spinal stenosis with complete blockage in one spot, nerve root compression, multilevel degenerative disc disease with several completely dehydrated discs, plus protrusions and herniations. The doctors are pushing for major surgery as soon as possible. I am wondering which peptides might help or anything else really, not only peptides. I am leaning toward klow and ARA290. Any suggestions would be welcome.
