Been in the pwo world since mid 90s so I've tried pretty much all the notables and OG formulas. I've also used the original Arez and Arez Titanium. This rerelease of Titanium reminds me of Dark Labs Flame but has a bit more pump and may be less jittery for newer users. Having a high heart isn't the greatest when you're shooting for volume or strength. If you're heart is beating too high, you'll get winded too soon for any good volume work. Also, that high heart rate will impede your strength/power sets because you can't summon the right intensity when your heart is already working too hard before you even get into the strength sets. So, this new Titanium hits you fast, but without the jitters. Since it hits fast, I'd start with a quarter scoop at home for smaller frame people and newbees and by the time you get to the gym, you can gauge how much more you may need from there without overdoing it to quick. On the taste, its light and good.
