i'm pretty sure the bottles were anabolic steroids - after a bit of research, there is a real life product called Axiron which is a testosterone replacement product and the name Axiron is remarkably similar to A-Xeron which is stamped on these bottles.
Other clues backing this theory up, it's a 10ml bottle and states I.M use only - anabolic steroids are injected directly into the muscle and also appear to regularly come in 10ml multi-use bottles with a sealed rubber cap like this one. I have no idea why he has them mind you, my only guess is that he's selling them himself or is being used as a mule if this is of course a correct observation!
