I have some test E sachets and want to test to make sure they are legit,The test is in vials now. Weird question but if I went to CVS and bought a steroid drug test could I inject the test onto the drug test to see if it comes up real/legit?

Anyone know of any other ways to tell if it is fake.. The color looks correct but I just wanna make sure and all.. Its super test btw and hurts like a mother , but i didnt get anything out of it as far as gains go and still have a ton left. First cycle that I havent got anything out of while using gear.
