That you can gauge by the harshness of the sides. I would watch for lethargy, lower back soreness/tightness/pump, mood degradation, and urine color.

For me these would usually start hitting hard around the beg to mid of the third week. I would bang out a great workout, then i wouldnt be able to keep my eyes open, and running was impossible with the lower back issues. And As I stated before some slight depression that lasted through pct.

I never had my urine become dark, some people have when they push the dosages. this is a sure sign your kidney's cant handle it, and you need to go see a doctor asap.
