I have been on var for 40 days and started at low 20mg/day now I am at 100mg/day and feels great in the gym. I take var only and don't take any liver support or anything cause I've been told to keep it for when I start the pct. But today I feel like my right kidney hurts a little it's a numb pain in my mid-lower back. Any suggestions for supplement to take that will help with that or advice pls. thanks.
