Just YHCL + caffeine for morning fasted cardio is usually what people do.

I'm about to try something a little stronger, interested to see how it goes.

lol at needing a pre workout to actually workout

why rely on fat burners to lose weight lol
fix ur diet

Unless you monitor your caloric intake, you will not lose weight if you're not eating a deficit.

As far as not feeling a "rush" when you take these stims, you're just tolerant. Lay off all stims for a few weeks and you will begin to feel them again. However, you'll probably never feel the "rush" you had when you first took them.

However, thermogenics are a waste of money as far as effectiveness vs price. Buy some E/C (ephedrine & caffeine) for a real effect, or some Clen (but I'm not allowed to go into much detail about this due to restrictions of this forum. Google it)

HYPHY MUUUUUUUD

rip

this lol

since you said you wanted a preworkout, I'd give Nitraflex a try. Made by GAT.
