BY FAR, the worst is USA. Gear may be available here, but law enforcement against drugs here is obsessive. The war on drugs has a cult-like following here among law enforcement. In other countries like Canada, gear may be illegal, but the worst that will happen to you if you, for example, try to import it, is that customs will seize it. In the US, you may get a visit at 3:00 am by a group of men dressed in black ninja-like outfits and carrying MP-5 submachine guns (aka the DEA). Juicing is not worth it here unless you happen to like prison.
