Alright, I went ahead and gave it a shot.
My vial is the LC256 Fat Blaster, already mixed, 10mg. First dose was .1 mg - 10 units, purely to see if anything bad happened. Nothing did, so I bumped up to .25 - 25 units, still fine. A week on, I'm now at .5 mg - 50 units, taken 2 x a week, and still no problems.
I'll likely nudge the dose up a bit more, then hold steady there for a few weeks.
Can't speak for how it hits anyone else, but for me it's been a help. I take it in the morning ahead of my workout, and it hands me a big load of clean energy plus a strong "want to." Like, I want to crank out five more reps. So yeah, it's doing something for me.
