Letrozole DOPING DETENCTION TIME in SPORT, and Serm.

[yoshimistu]

Hi guys good evening, we often talk about the possession of steroids and their metabolites to prevent exposing athletes who abuse steroids in competitive sports practices, BUT, nobody talks about the possession and availability in the blood and urine of Serms or antiestrogens in general. For example, we known that nandrolone is recognizable up to 18 months, but for example a letrozole? does anyone have any news or some study / table about it.
thank you.

Identification of the aromatase inhibitor letrozole in urine by gas chromatography/mass spectrometry - PubMed

Letrozole (1-(bis-(4-cyanophenyl)methyl)-1,2,4-triazole) is used therapeutically as a non-steroidal aromatase inhibitor (Femara) to treat hormone-sensitive breast cancer in postmenopausal women. For doping purposes it may be used to counteract the adverse effects of an extensive abuse of...

Anastrozole is over 24 days as shown in the below study, I'd therefore suspect Letrozole to be similar.

I'd email WADA and ask them, I'm sure they would reply.

thanks my friend i'm scared by metabolite.

 

[yoshimistu]

because surely the substance has been extinguished but I'm afraid of its metabolites

Just read some of your threads. Seem like you tried a lot of anti estrogen, peptides etc. Are you a high level athlete just looking for an extra edge or a bodybuilder?
Just curious not trying to lecture you on ethics.. without giving away too much curious to know your sport and how the results have been with just anti estrogen.

 

[yoshimistu]

High level athlete but i don’t want to say more in public.

What reason do you have to take Letrozole?

 

[yoshimistu]

Doesn’t matter, it was around 5-6 month ago. And im scared from drug test positive.

what’s / who is your testing agency ?
Depending on who, and what kind of test I’ll tell you, some are spot on and some are so far off, I had one test come back negative, when they had my guy dead to right ..
So I know for a fact mistakes happen and the test they are running aren’t always 100%.. I also can vouch this for myself for a test I was negative (metabolites) when I know for a fact I should’ve been positive... and this was a few months ago... I don’t believe nor trust any of the shit out there to be honest ..
