mine doesnt have a sticker on the bottom or anywhere acctually

i dont think i have recieved a product code when i got my parcel there were ''andora tessera crystal'' but when i opened that box inside there were the testosterone i ordered i think i tried to verify authenticity using the batch number which i believe is wrong so i dont know how to verify it

hi i bought 3x test c from driada and when i recieved the product all of them have the same batch number and all of them seemed to be scanned 4 times before i ordered from driadashop.to which i believe is the right site is this common for test or something is off?
