I heard they take hair samples and not a urinalysis. Hair sample goes back years. My life has changed since then. Hows that work? And what would I owe if I dont pass?

Follicle tests do not reflect years of history... if you've been clean for six months, no worries.

They say they do a follicle test, but I have not experienced one. I think it's on a case by case basis.

Urine only

They do urine samples

the anti-doping analysis I do not know what happens.
