BUN

Prospect

Member
I am currently on 200 mg of test once a week. Been on TRT for 4-5 years and never done any cycling. Recent blood work came in and BUN is at 31. My readings show high BUN can be from high protein, dehydration, intense exercise, etc. Dr wants to visit with me about it. I’m afraid he will lower my test because of it. Is there a supplement to lower it? Surely don’t want to eat less protein or quit working out but know he isn’t going to keep my test at 200mg if I don’t show improvement. mover the last 4 years my BUN has went from 20 (2017) 28 (2018) 24 (2019) and 31 (2020). Any suggestions on what I should tell Dr would be appreciated.

Gents, Happy New Year to you both. I trust and hope all is well.

This fellows post intrigued me, wanted to help him out and hopefully tagging you two may just do that.

What is a BUN and how can this man go about lowering it? Would intentionally lowering it possibly have adverse effects that need to be addressed? I'm sure there are better questions to ask on his behalf, I'm not sure what they would be though.

Thank you gents

Here's to a happy and prosperous 2020
 
I’m going to bump this thread in hope of a response from someone experienced in this area. My test levels have always been in range with 200 mg a week. I don’t feel like I’ve abused it and I’m not ignorant enough to say test isn’t part of my elevated kidney problems. Like many of you I eat 1.2-1.5 grams of protein per pound and work out 5 days a week. I think hydration could play a role but searching the internet I’m having a hard time seeing if my levels are dangerous or slightly above normal for guys like us who don’t live normal, lazy ass, eat like shit lives like most of the population. Thanks in advance

Blood urea nitrogen, it’s a waste product created from digesting proteins that your kidneys take care of. High protein, low blood volume, decreased filtration etc can cause an increase. Idk how much protein you eat but I can’t imagine what I’ve read some taking in, like 400g, being healthy.

Thank you for the spoon feeding!

OP - I wonder, how often do you take your 200mg dose?

Edit, saw the once a week.

What about backing off to a ten day split? Maybe pin e5d to keep stable levels? Would be a minimal change...

You already have your answer in what you read. It is not the TRT.

What is your age?
What is your % body fat?
Are you AA?

Your eGFR combined with BUN and Creatinine would concern a doctor with regards your kidneys.

As to lowering BUN and Creatinine just to make a blood test happy ... stop the exercise, eat little protein and drink plenty of water a couple days before the next blood test.
 
thanks for the response! I appreciate it. I’m 40, pretty lean for 250 lbs, never cycled anything more than TRT dosages. I’m going to go meet with my dr and take your advice and retest my blood. From your knowledge do you contribute anything to the TRT or is it the other factors? My test levels have been in range for years and I don’t want to lower my dosage unless it’s a must.

Thanks for the response! I wil definitely consider more days in between pinning. I’m hoping to retest with a few rest days and less protein along with lots of water and see what it does.

It is very unlikely that 200mg/wk would affect your kidneys. There are some AAS users that stop because of kidney problems but it can be genetics as well as whatever else they have been doing. Your TRT is not even remotely close to what many AAS users take.
You may wish to take your yearly blood tests and put it in a spreadsheet. That may show patterns.

You have an older picture with similar bodyweight 1 month body fat cut If you are similar to that now, you are neither fat or lean. This isn't to be impertinent but rather how your doc will view things. The relevance is that eGFR is a very crappy, inaccurate test. It is just a crude marker for docs to look at. Skinny, malnourished people will show incorrectly high eGFR whereas lean, athletic, muscular people will show incorrectly low. One member in his 20's always had readings like your current one. When they did an inulin clearance test, the real GFR was more than double.

You could ask your doctor for that. Another test if you are in USA is a kidney stone test [ LabCorp's Litholink]. It is just a 24 hour urine and blood test sent to Chicago. Besides stones it shows all the stuff the kidneys are processing which indicates real function. GFR is more about blood flow through the kidney rather than what it is accomplishing. You may find with high protein you are passing a lot of calcium oxalate. Stones are one thing because they are treatable. However one can have calcium oxalate crystals which causes irreversible damage.

Now there is no point panicking. Rather direct the doctor to the test if he isn't thinking about it. That is where his attention should be rather than TRT.

If you do the test, eat and exercise exactly as you have doing. Your goal is to see what has been going on, not to see how good one can make a test look. Then with more accurate info, you can decide what to do next, mainly less protein (dietary protein forms oxalate and higher BUN and Creatinine).

Hopefully this is helpful

I also had a low egfr that was troubleing me. I went to see a nephrologist and he said that the normal egfr test was meant for old ladies in their 70's, not for people like us. He ordered a cystatin c test that he said would give better indication how my kidneys were doing. Normal blood test. My kidneys were fine.
