Kidney Problems
The kidneys can undergo more possible strain during anabolic steroid intake. Kidneys are involved in some of the filtration and excretion systems of the body, and as such, when a foreign substance is administered, they necessarily work harder. Some steroid users have noticed very dark urine when on a cycle, and this is indicative of the kidneys working overtime to accomplish their goal. One of the major offenders of this seems to be Trenbolone, which turns the user s urine a very dark color unless enough water is taken in daily. Also, even though I know you re probably getting sick of hearing this from me, the possibility of side effects is dependant on both dose as well as compounds administered. Some steroids (Nandrolone) are even used to help treat people with Kidney problems! So clearly, they aren´t as bad as they´re made out to be with regards to possible kidney issues.
