Hi,
I just got my blood test results back and am concerned about kidney function:

BUN (Blood Urea Nitrogen) = 27 (reference range 7-23)
GFR 65

I'm on a high Protein diet (1 gram per pound of body weight)
Creatine supplement 3 grams per day

Do you think I should be concerned and should cut back Protein intake or creatine supplement?

Age 45
6 foot
185 pounds
12% BF
On TRT of 125mg Test Cyp per week

Thanks!
