Used fina on and off for a year or two. This time my kidneys got really sore and I'm only 6 injects into cycle. I drink a lot of water but I piss excessively and have a sore pain just at my waist line on my right side. I need to have some advice on this and need to know what supplements to take to help support the kidneys. Is this a common thing while on fina? I have read over and over about the kidney toxcicity of fina but have never had any problems with it before and need some input. Do the kidneys repair themselves over time when off of aas use? Please help me asap. THanks in advance from a new member.
