I loved AMT a few years back.. what a great substance.
I loved 3-meo-pcp too, but if OP it concerned about being blown away that might not be a good option because it is strong stuff and that experience can go from weird but fun to really frightening and out of control pretty quickly.
If it's available you might give 2-fdck a go. It's not as exciting as the 3-pcp but it is significantly more user friendly and is like a light ketamine.
Regardless of whatever you end up buying and trying, make sure you weigh out doses very carefully (buy decent scales if you don't have them) and start with small doses before working your way up. RC benzos - all benzos, really - can be insidious and can fuck your whole life up in just one day/night if not treated with caution.
Be safe.
