WOW! This is definitely the most powerful and intense stimulating, energizing dose Ive ever had. I had just woken up early this morning, put my headphones on and listened to this, and within 15-20 minutes I was WIDE AWAKE. All my sleepiness? GONE! And without the negative effects of stimulants (jitteriness, anxiety, high blood pressure, etc). It?s a potent yet positive energy that lasts all day. The Speed dose actually forces your body and mind to wake up; at least that?s what it does to me. I?m so thankful that I have this for when I need to get rid of morning grogginess, get motivated, sharpen my mind, keep alert, and boost my mood and euphoria. Now I?ll never have to worry about feeling sluggish all day again, as long as I have Speed to fall back on! The description is exactly right - this is very intense and much more powerful than other stimulant doses. I highly recommend this for seasoned dosers who want to feel immediately charged in the morning or at night. Thank you so much I-Doser. You?re a true lifesaver! Five stars!
