a good combo in my experience. DTP can make u a lil more sensitive to stims ( n also seems to a mild stimulative effect on its own- mild but i feel less of a need or desire to consume stims when taking it n a 2 tab dose upon rising has me awake n ready for the day) so that is the only thing to pay attention to, if anything at all. I have used it in conjunction with JP8, Jack3d, n jus recently w/ White Flood, pumps, energy etc are crazy in each case. I jus started another bottle of DTP this week, i find it to be very effective (i prefer it to DTH). Honestly, "kitchen sink" can be a very good thing with herbals...synergy. Granted sufficient quality/potency n amounts are there, n it seems to me Chuck knows what he's doing+has ethics, n simply doesn't want others biting off his formulations, everything from GD i have tried has been top notch, other than I find that i am less responsive to DTH than DTP. Enjoy the stack...
