Kaged muscle Pre-Kaged is great - well dosed and effective.
Stimumax is another well dosed product I use by strom sports.
Redcon1 Total War is also great for the DMHA - different kinda feel to the usual ones - if you want a buzz that works for most.

As you know, there are loads out there.

I'm a fan of using pre as and when you need it, not all the time and I recommend that.
