weightlifter

I was talking to someone and they said that cordyceps was something that a weightlifter should take cause it has a lot of good things in it including b12 that we need anyone try this stuff and where should I get it ?

I injured my knees playing pickup basketball when I turn a certain way and felt my knee buckle. I went to the doctor and he said that it was just a strain and I should take some time off. My problem is I'm a weightlifter and I left at least three times a week. Should I try to train through this...
