Hi
Is it's 'Stacker 2' as in diet pills? if it is then you really have no worries, when anyone does a drugs test, you are tested for the illegal substances.
What you are taking isn't illegal, especially if you are buying it from a pharmacy.
Can I ask why are you taking so many supplements ?

Your good bro. I take over 30 pills a day not including my serums, AI's etc. to keep my hormones in check. Bodybuilders for life huh!!!!
Naaah your good the only thing supplement whise you would need to be worried about in a drug test if they were testing for AAS (steroids). Which is a very expensive test so I'm sure there not. All the above supplements you stated above are safe, effective and completly natural. Your good.
