I have danced many times with DNP, each time a more frightening experience. If memory serves, I have run more cycles of DNP than I care to remember with really only the last one bringing me any real problems aside from the expected side effects.
On that last cycle I went higher than anyone should ever dare to go - 800mg ED. I ramped up just like every time before, but my second day on 800mg was almost my last day on earth. I had the usual side effects, only more greatly pronounced. It was winter and I had no job, so my days were spent inside trying to fight the urges to eat everything in sight.
The first day of 800mg was rough. Every motion required the utmost effort. Just walking to the bathroom was operose. On DNP you don't sleep, you nap repeatedly. I would fall asleep, wake up, and fall asleep again, repeating this pattern all night. I couldn't sleep on the bed anymore because I would soak it in sweat. I was on the floor.
Around 3am I woke up to visions. I crawled off the floor and onto the foot of my bed, where I lay gasping for air. For some reason, I looked through my door and through the small hallway that lead to the kitchen. I couldn't believe what I saw. There were silhouettes of men, women, and children that looked like living shadows. They would peak around the wall of the kitchen and into my room. One would walk into the doorway, wave for the others to come to him, and they would just stare at me until I would move and they'd run away. Eventually a "man" walked through the hallway and to my door. I smiled, laughing at the situation, and he and the other shadows disappeared. Strange.
After my 800mg dose of DNP the second day, I passed out for hours on my bed. I would wake up every now and then with a migraine, soaked in sweat. Eventually I could only lay on the floor.
I stayed asleep for the remainder of the afternoon until about 7 or 8pm when my parents woke me up. I could barely open my eyes. My mom was scared at how hot I was and said that I was going to the ER.
When my dad and I got there, he had to walk me into the waiting room. The woman called me to the counter to answer some questions and sign some forms. I couldn't write at all. Everything I started to write would trail down and off the page. I couldn't stop my head from falling, my eyes from rolling, and my hands from shaking.
We waited for some time until the doctor called us back. I told him my symptoms, yada yada yada, and he took my temperature. It was 104.7. He did some kind of test for infection and found out it was a massive bronchial infection that was about five minutes from becoming pneumonia. So he said, anyway. He gave me an IV bag full of antibiotics, some albuterol, and a horse pill sized Motrin. I lived.
I have a huge DNP .pdf on my computer that contains - as far as I can figure - every study ever done on DNP and humans. The crazy thing is you'll have one guy take a dose like I did and be just fine. Another guy will be in the same room DNP and burn to death (seriously). DNP is safe for some people, but the only way of knowing if you're one of them is to try it. But with that test comes the harsh truth that you may die as soon as you start. Everyone thinks they'll be fine. I KNEW I was going to be fine. My experiences with DNP and other chemicals of that sort have tought me that it just isn't worth it. Fat loss is one of the most fleeting things you can ever "gain." Some people - like the old me - will almost kill themselves to get something that a Thick Burger can abrogate. It just isn't worth it.
P.S. For those who advise telling your doctor what you're taking, I say go ahead. It's good for a laugh. I told the ER doctor what I was taking and how it worked, and he said, "what in the hell is oxidative phosphorylation?"
