Google steroid detection times and there s a chart or
Worste case go to passyourdrugtest.com a Nevada based comp. They too have a drug detection time chart. And they sell products to wash ur system clean be it weed, meth, opiates, hair test. I ll vouch for them
The metabolites in ur blood unfortunately ( excreted in urine ) tend to stick around for quite some time w deca being detectable depending upon ppm prosecutable amounts for 6-9 months depending on the..no shit..sophistication of the equipment they use. They have to request a specific gravity on this and it s damn near infallible.
Long way to say " I ain t sure but..."
Good luck..
