Different lot #'s.....Which are legit?

[Prime Time]

I just got some ara test 2500. 4 vials. 2 of the vials have the same lot #. the other 2 have the same #, but it is different from the first 2. Which lot #'s are legit? Both? They have black tops. Someone said the black tops havent been doing good. If anyone has the same numbers as mine i would like to know. Especially whether u had good gains. Any info is greatly appreciated. Thanks bros.
