No it wont show up on a piss test. But if you were worried that it would and you could go away for 45 day's then why even take the risk? I do enjoy a flexeral every now and then though. Peace
holysmokin Reviewed by holysmokin on . Flexeril well heres the deal. depending on the situation, im gonna have my monthly urine test wednesday the 2nd. today i came across some flexoril (cyclobenzaprine, muscle relaxer) and i hate 10mg worth about 30 mins ago. does this shit show up in a drug screen? i mean its not like fucking heroin or anything, but the least fuck up will get me gone for 45 days and i cant afford that shit right now. if you know, please tell me. thanks a million.
