I have some test E that I will use for 7 weeks, at week 6 I will do my mid cycle bloods. Then I will be running a different lab the remaining 8 weeks. But I want to check that the test I switch to is legit so I'm going to take new blood to see were my test levels are at.
How long do I have to wait after switching to the new lab before I do the blood test to be sure that the old test is not "affecting" my new levels? Hope you understand what I mean.
