had partial knee replacement done last tuesday. had a talk with rr before and decided this stack would be good for maintaining some muscle while i am inactive. the drugs i am on have killed my appetite, but i am still maintaining muscle tone with about 3 pounds of total weight lost. physical therapy has been been rough but my therapist is amazed at how fast i am improving. so far i am impressed with how things are going. btw i also got reduction to keep weight down while i rehab but as you can guess i haven't needed to use it yet.
