DHT blockers and impact on blood test and drug screen

[allout13]

Ok, so we all know DHT blockers like Propecia and its active ingredient Finasteride. Their usefulness while on test, deca, etc have been widely debated and talked about here.

What I'm wonder is: What affect does it have on a drug screen or a blood test. I've heard rumors that it causes all types of problems and may not give a clean reading on different hormonal levels. Also, i've heard it may block the test/blood work from seeing that you have different AAS in your system.

Basically, does anyone know if any of this is true? Or what affect it really has?

Nobody has any info on this?

Technically, they're not considered steroid ancillaries so they shouldn't be screened for, but even if they were there's a very sound built in excuse/reason for their use...RIGHT???

you should NOT use finasteride on a deca cycle.....

What about finasteride messing up the detection of gear during regular urine tests? It seems to be widely thought of that it does have some masking tendencies (see NCAA/Olympic/other sports regulation of finasteride), but does anyone know to what degree? Or what specifically shows up?
