Stimulants that don’t show

I need a stimulant that doesn’t show on a drug test 

Most of them  will not if you give 2 to 3 days to wash out and keep using.  I know I used Butylone  night before going to Lab to do the standard 12 panel test. For job pre analysis and to my surprise Nothing.  Night before downed 250 MG and went to 

Strip Club. Felt all washed out next morning and to my surprise --all Negative readings.

Got enough for Personal us as will need for 5 to 10 years . However you can get 4-MEC or Methylone ( BK-MDMA) ..... I am very interested!!!!!

Old thread but it's something I'm curious about. Of course it depends on how many panels they're testing for but it seems they're much better at finding close relatives. Obviously the usual stim suspects are a fail but I have no idea what else is on the wanted list.

I had friends that were taking loads of ritilin and getting tested for court no problem. That was almost 10 years ago and things change fast but that group of goods is probably safe. I wonder about cathies and the other groups, how close they are to amphs and what they metabolize into. They probably don't have the time or $$ to bother with a lot of it.

On the other hand. One time I'd done a xanxax bar. Tested over 100 hours, 5 days later, and they picked up a few nanos of 'metabolites of desinger benzo'. Whatever that is. When they tried to zero in on what it was it vanished. We had a laugh over it, it was for a med clinic not a job or court and they love me but I wasn't happy. I already knew none of the xanx in my area is the real deal unless you pick it up at the pharmacy, it was still odd. The worry is that some types like clonopin and valerie can stick around for 2-4 weeks and these outlaw ones could be unpredictable. Stick around in the same way. Obviously water soluable is better but it also means it doesn't work for long.
