I thought I read something here about this some time ago. I take tudca for my liver. What do you guys use for kidney support. Is it just a take n2 guard deal, or it there a dedicated for kidneys supplement? I take a lot of tren and have had elevated numbers, a bit elevated, not crazy high. I've read that by the time the numbers elevate, kidney function is diminished by near 40%?????????????? I can't have it I'M WAS TOO OLD. Any advise would be great. Thank you.
