55 years old and I have been on Repatha for about 2.5 years and it has dropped my LDL from 160's to 35 however I have very mild weakness in the legs while performing normal activities and it is much worse if I try to race my bicycle. I am thinking about taking a break to see if that changes to confirm my suspisions. Anyone else on here have issues with high level exersize on Repatha ? has anyone tried stopping and how long did it take for your side effects to resolve ?
