I just had my blood work done. It all came back great. Reta didn't "show up" at all. What did concern me was all the other peps, etc. that might have an influence. For example, I was taking creatine to help with muscle growth. Apparently, it will show up as a high level of creatinine, which indicates a kidney problem. You need to either cut it out, or explain it to your doctor. Just to be sure I cut out everything except my reta / tirz stack a month in advance. I won't bore everyone with the rest of my stack, but it is a good idea to run it through AI and make sure all of your other extra-curricular peps don't create wonky results.
