I would look for the silver hologram on the box and the bottle, also i just saw a fake batch of enanthate from Brovel and the letters were raised on the top of the bottle so we can throw that idea out the window, also the colors on the bottle and the box should fade in together, another thing is wipe the lot number and label hard with ur finger, if it smears i believe that it is fake, but the hologram i feel is the number one thing i look for
