Im 47 and my semen turned orange/yellow since yesterday. I started taking a different natural testosterone booster the day before, Force Factor test 180x alpha (very expensive one from GNC). I've been taking a different natural testosterone booster for 4 months prior. I also take VSL#3 (probiotic), a multi vitamin, workout, smoke, drink beer. I have no pain and the semen smells normal with normal texture ....What could this be?
