How far out are you from surgery? I had surgery on my quad when I was in my teens, and I considered myself 'recently operated on' for a full year....took it real slow with the leg work...
You need to tell us WAY more about yourself: age, wt, training hstory, cycling history (bulkers vs cutters vs compunds used vs gains/sides from these drugs, etc ie whatever else you can add).
Realize, no one can recommend much without more info.....Help us out here.
