Plasma C-Type Natriuretic Peptide: Emerging Applications in Disorders of Skeletal Growth
Although studies in experimental animals show that blood levels of C-type natriuretic peptide (CNP) and its bioinactive aminoterminal propeptide (NTproCNP) are potential biomarkers of long bone growth, a lack of suitable assays and appropriate reference ranges has limited the application of CNP...

"In healthy lambs (aged 1–30 weeks), plasma NTproCNP and CNP levels [16] correlate with metacarpal growth velocity (r = 0.55 and r = 0.4, respectively). Values of plasma NTproCNP fall to stable levels (20–25 pmol/L) after 30 weeks of age, when linear growth is largely complete. Notably, in healthy, rapidly growing, 4-week-old lambs, administration of long-acting bovine growth hormone (GH) for 12 days increased plasma insulin-like growth factor 1 (IGF-1) levels more than 2-fold [24]; however, plasma CNP products and metacarpal growth velocity were unaffected. This finding suggests that neither GH nor IGF-1 directly stimulates CNP gene expression, and that any such increase is contingent on a demonstrable increase in bone growth."
Just more evidence that alot of these theories seem to have clinical studies backing them up. CNP gene expressions seems imperative to bone growth, which makes sense because it's expressed at it's highest when children and animals are STILL growing, and begins to fall near the end of skeletal growth.
As you can see, high IGF/GH doesn't do anything without proper CNP expression. I'm not even sure that stimulating CNP/GC-B will do anything for people with closed plates as there is no more growth cartilage to act on, but I've learned so much over the past few months that I was taught was impossible that I'm open to anything at this point. Keep searching for answers, guys.
