Pre-employment screens are easier. Every one I've ever done, they let you be alone in the room. Get you some clean urine(either real or synthetic), put it in a container that you can put inside your underwear tight against your thigh to keep it warm.

The only thing you need to worry about is the temp check. Usually needs to be above 92 degrees. The synthetic urine sellers have heating pads, temp strips and containers for sale with the urine.

There are fake genitals that can be worn aside someone's real ones attached to bags of urine. Synthetic might work, but a clean friend's will work too.

I haven't faked one but lots of cardio until a couple days before will help it get out via fat and lots of water worked. I dab daily and it took ~21 days to pee clean as a fairly fit person.

Me personally? No. But I'm friends with people who make a lot worse decisions than me, and people who got on a methadone clinic who wanted to continue to abuse drugs.

So first things first, always assume it's monitored, if it's a drug test for anything that matters it's monitored. This means dilution is your only route. Maybe you'll get lucky and you can use someone else's piss, but betting on that for a place you're not well aquatinted with is a horrible idea.

Most labs aren't super complex from what I've seen, they look at the color, and they look at protein. That means you dilute with a bunch of water as always, you take a b complex to make your water piss appear yellow, and you take creatine to make a normal amount of protein show up in your piss. This has never failed any of my friends in any situation they've found themselves in. Employment, probation, custody, ect.

I used quick fix at a official lab (Labcorp) required for EMT school

I have had success in the past with The Stuff but that was like 10 years ago so YMMV
