I'm going to preface this by saying that the miraculous has happened: researchers have actually gained ethical approval to conduct a study on bodybuilders doing some fairly typical multi-compound cycles at normal doses. Fucking amazing!
On the other hand, I'm going to say that I've not read the full study, which I don't have access to yet. And they don't appear to have controlled for diet (see protein intake), which is annoying. However, protein intake alone hasn't generally been recorded to cause the changes noticed here.
What the researchers appear to have discovered is that boldenone is unusually hard on the kidneys. Increased renal cortical echogenicity is a nonspecific but significant finding that suggests the presence of various underlying renal abnormalities, while the thickness of renal parenchyma is a measure which predicts renal function pretty well (thicker = poorer function).
We tend to think of orals and compounds like tren as being at fault here, but the group using dianabol were actually relatively unaffected, so this study is certainly food for thought...

BACKGROUND:
The aim of this study was to investigate the effect of anabolic steroids on kidneys in bodybuilders.
METHODS:
Twenty two bodybuilders were included in the study. Participants were divided into three groups according to the scheme of steroid usage: Group 1 (n=8, intramuscular 500 mg testosterone enanthate, intramuscular 400 mg nandrolone decanoate and oral 40 mg methandrostenolone for 12 weeks), Group 2 (n=7, intramuscular 500 mg testosterone enanthate, intramuscular 300 mg nandrolone decanoate and intramuscular 300 mg boldenone undecylenate for 16 weeks) and Group 3 (n=7, no steroid intake). Blood urea nitrogen (BUN), creatinine (Cr), urine microalbumin and electrolyte levels were measured. Renal volume, cortical thickness and echogenicity were obtained in ultrasonographic scans.
RESULTS:
Renal volume, cortical thickness, echogenicity and protein intake value were significantly higher in group 2 than group 1 and 3. Plasma levels of BUN and Cr in group 2 were significantly higher than other groups (p ? 0.001). Urine microalbumin and electrolyte levels were normal in all groups.
CONCLUSIONS:
The results of this study indicate that high protein intake, steroid usage, particularly the schemes, including boldenone undecylenate increases cortical echogenicity, thickness of renal parenchyma and renal volume in bodybuilders.
