Spike affects people in different ways, for me, someone who is the very definition of stimulant resistant; I don?t get very stimulated off of any dose of Spike. (I?ve even tried stupid doses of both rapid release and Nano-dispersed.)
It does (at 3 rapid release pills) something else entirely. It literally lets any knowledge you have flow out at an alarming rate, you never (Or I never) get a ?On the tip of my tongue? feeling whilst Spiked. You?ll find in conversation you?ll get far more detailed and generally talk more.
I have stopped taking it while losing weight for summer, as HOT-ROX and Spike are contraindicated to be taken together.
I didn?t go through any withdrawal type stuff, but you do feel naked once in a while, especially if someone starts arguing with you. On Spike, I love arguments! I can recall more details then if Non-Spiked.
I still have some, and on days I know I?ll need to be 100% on my game I skip the HOT-ROX and take some Spike.
Hope that answerd a few questions.
