I've recently received some of P's powder and some of D's crystal and before I start my log, wondered if there's and reason not to, or indeed any point to, run both together? I only ask as I've used both before and noticed incredibly different effects. On powder, I would be literally dripping sweat but my temperature barely reached 98F, whereas on the crystal, I rarely even broke sweat but I felt constantly hot and occasionally downright terrible. From what I've read of others logs, my tolerance is very (read annoyingly expensive) high as I didn't notice any effects until I was averaging 8 to 10 of P's caps and 5 of D's.
