so we all know cll will cause the bone to grow but everything else will not grow(atleast to the same degree) which could potentially cause some problems after the years.
on the other hand if a persons growth plates are open or even just closed we can alter the hormones and gene expressions to some extent introduce externals like synthetic hgh, ai's, anabolics, peptides and other notorious drugs to try and push the long bones further apart in the effort.

personally i think that cll does offer risks but in face of systematically manipulating chemicals(which effects everything) in the body we dont even understand 10% of human body to the full, those are just minor risks. with cll even the risk of being cripple is low as everything is controlled but by injecting stuff that body doesn't want in the first place, one is possibly fking up his glands tht produce hormones as is evident with anabolics (the testes stop working and shrink) possible risks of damaged sxx drive later in life, cancer, diabetes, stroke, digestive issues, brain damage and plethora of organ related issues. and issues we don even know the fk about cause we are far from understanding human body to a good degree. i think mb in 150 years closer to genetic alteration.

im long past growth plates closure at 25 so there is no way except cll on planet earth currently but if i was 15 and young and given a choice between the 2 i think i would not choose to put stuff in other than foods. if i was meant to live for 90 genetically then y should i force it to cut down to 50 and tht with a fked up system.
