My IGF-1 is at the higher end of the range 3 off being over. Though IGF 1 Binding protein 3 is almost below range, which suggests it’s not being delivered to tissues correctly, if i’m correct IGF-1 P3 stimulates collagen production. HGH measured in serum bloods was below 0.5<, so not sure about this. Going to try further testing

[Size=4]“IGFBP3 protein levels decrease during the progression of prostate cancer from benign prostatic hyperplasia (BPH) to its metastatic form.[3] Although, production of the protein does not cease completely. IGFBP3 is still made (at a lower level) by prostate cancer cells and secreted into the surrounding environment. However, instead of the full length, functional protein, IGFBP3 is found to be cleaved.[4] This prevents IGFBP3 from binding and sequestering IGFs and the growth factors are free to bind the IGF-1R and promote cell survival.”
