keeps

I have bee running 250 mgs of Test C for 4 years or so. My labs came back HGB 18.5 and HCT 53.3. I would like to start donating blood. My question is should I do a power red donation every 16 weeks or a regular donation every 60 days? Thanks in advance.

What tends to have the effect of improved sleep quality? What would a dosing protocol look like and for how long of a duration?
