Nandrolone on Blood Test

I’ve read that nandrolone shows up as testosterone on basic blood tests. However, Liquid Chromatography with tandem mass spectrometry (LC-MS-MS) can distinguish nandrolone from testosterone. I ordered a Quest Lab test that showed my testosterone had crashed. With the help of this community, my best guess is that the deca I had was compromised. (It did pass Dave Palumbo’s roidtest.com kit, which just tests for presence of nandrolone, but I’ve also read that his tests aren’t reliable.) Anyway, I went back to look at what method Quest used to test my testosterone and, to my surprise, it was LC-MS-MS. This made me wonder if maybe nandrolone was present in my system and not showing up on my testosterone reading (since that method can actually tell the difference). My source for the gear had a theory that I was receptive to the nandrolone in some way that was interfering with the testosterone (sounds dumb to me). Anyway, if any of you know for sure that it would have shown under testosterone unless i specifically asked for another category to capture the Nandrolone then that would put a period on it.

yeah that could be

Your deca is not suppressing your test levels. This has been mentioned to you several times. Your source fucked up your gear. If anything your tt levels would be higher….

I didn’t think it was the first time I asked the question. I didn’t think it was here. The nature of this question was how certain blood tests distinguish and report deca in the blood. Read carefully and you could avoid “mentioning it several times.”

If you are asking if nandrolone has the potential to show up as testosterone on a “BASIC” panel? the answer is yes.
If you are asking if nandrolone has the potential to show up as testosterone on a (LC-MS-MS) panel? the answer is no.
Hope that helps
