I have been on 500ml of test for 3 weeks. My labs were taken on Monday and I got results today. My test is 1234. what concerns me is my BUN is 24 in a range from 6-20 for normal. The best I can tell is this is kidney function. Would it be safe to use tbol in this cycle? I have been planning on making a log but wanted test levels back before I began. Any help concerning BUN numbers will be greatly appreciated. Thanks
