Hey guys, so long story short my dad is 59 and has always been a hard working man doing hard construction work and has seem to finally have taken a toll on his body. His shoulder is shot and can barely move his arm. They supposedly did surgery on him but in the end the drs just looked at it and said we have to open you up next surgery. They are milking the insurance and its just fucked up. My question is, is their possibly a peptide or something to help maybe heal?
