What over the counter supps can cause a false positive

The Gaspari novedex xt is ATD? and can show up as a false for Bold?

It all seems to be out of stock..

This latest study shows that ATD shares similar metabolites with boldenone. This has implications with athletes who are subject to doping testing <------ ATD is legal..

Metabolism of androsta-1,4,6-triene-3,17-dione and detection by gas chromatography/mass spectrometry in doping control.Parr MK, Fu?h?ller G, Schl?rer N, Opfermann G, Piper T, Rodchenkov G, Sch?nzer W.

The urinary metabolism of the irreversible aromatase inhibitor androsta-1,4,6-triene-3,17-dione was investigated. It is mainly excreted unchanged and as its 17beta-hydroxy analogue. For confirmation, 17beta-hydroxyandrosta-1,4,6-trien-3-one was synthesized and characterized by nuclear magnetic resonance (NMR) in addition to the parent compound. In addition, several reduced metabolites were detected in the post-administration urines, namely 17beta-hydroxyandrosta-1,4-dien-3-one (boldenone), 17beta-hydroxy-5beta-androst-1-en-3-one (boldenone metabolite), 17beta-hydroxyandrosta-4,6-dien-3-one, and androsta-4,6-diene-3,17-dione. The identification was performed by comparison of the metabolites with reference material utilizing gas chromatography/mass spectrometry (GC/MS) of the underivatized compounds and GC/MS and GC/tandem mass spectrometry (MS/MS) of their trimethylsilyl (TMS) derivatives. Alterations in the steroid profile were also observed, most obviously in the androsterone/testosterone ratio. Even if not explicitly listed, androsta-1,4,6-triene-3,17-dione is classified as a prohibited substance in sports by the World Anti-Doping Agency (WADA) due to its aromatase-inhibiting properties. In 2006 three samples from human routine sports doping control tested positive for metabolites of androsta-1,4,6-triene-3,17-dione. The samples were initially found suspicious for the boldenone metabolite 17beta-hydroxy-5beta-androst-1-en-3-one. Since metabolites of androst-4-ene-3,6,17-trione were also present in the urine samples, it is presumed that these findings were due to the administration of a product like 'Novedex Xtreme', which could be easily obtained from the sport supplement market.

Nice fucking find gammer.

Hey needto, Im an old school member here, I pm's you earlier about some of your products. Ive been talking to Radar about them, but he said you would know more. Please check your pms as this is an important situation.

Yes sir. Find that or any brand of atd and you are golden.
Go to ntbm forums, go to the kill that shit plaza and put an ad out looking for some ATD.

Is the ATD on the market today still an actual pro hormone that will show positives? I thought I read that the most recent ones will not.

ATD is ATD, no difference between atd made 3 years ago and recent. Always check the nomenclature to see if compound is the same.

Gamer, what do you take in from reading this? Does this mean if they do a more advanced test, that they can tell it is Boldenone, and not ATD?

Something to think about:

Immunological interference of the synthetic aromatase inhibitor 1,4,6-androstatriene-3,17-dione (ATD) and its metabolite(s) in the radioimmunoassay for testosterone.

Donaldson MD, Forest MG.

Radioimmunoassay (RIA) for testosterone (T) in unchromatographed plasma extracts from ATD-treated rats gave spuriously high values for T. Cross-reaction and chromatographic studies subsequently showed that ATD and, to a much greater extent, its metabolite(s) were responsible for this overestimation. Celite column chromatography proved to be an effective way of separating T from ATD and its product(s) of metabolism.
