DNP - Dinitrophenol
DNP (2,4-Dinitrophenol)
DNP (2,4-Dinitrophenol), an industrial chemical with various applications, has gained steady popularity as a fat loss tool. Boasting an astounding 50% increase in metabolic rate, it is able to contribute to reported fat losses of 10-12 pounds in 8 days of use. Classified as an "uncoupler of oxidative phosphorylation" medically, it is quite dangerous as there is no negative feedback system that may deal with overdoses. Specifically, there is no upper limit to the increase in body temperature that may be obtained with its use.
Introduction/History
Competitive bodybuilders and many others are continually on a quest for leanness. Used by the hardcore since Dan Duchaine's reporting of it a couple years ago, DNP (2,4-Dinitrophenol) has managed to steadily gain popularity as a powerful tool for weight loss. Interestingly, DNP was first used to ignite TNT in the early 1900’s. In 1931 a study released by Stanford University declared that DNP was able to cause amazing weight loss; subsequently it found its way into many diet potions and medications; regulation was much less strict during this time than the present, and many of these products were available over the counter. Two years later DNP was banned by the FDA as a dieting agent due to its inclusion in many OTC dietary supplements. The FDA was a new organization at this time and acted in a rather brazen manner, with the absence of any set procedures for taking substances off the market. Granted, there was only a 1% incidence of cataracts over a large population (around 100,000); nonetheless it happened (although interestingly, exclusively women). However, there are now ways to counter this which will be covered thoroughly.
The comparisons to the current drugs used for dieting are astounding, at least in terms of thermogenesis. While the ECA stack has been shown to provide approximately a 3% increase in metabolic rate, DNP can deliver a relatively controlled 50% elevation in resting metabolic rate. The thermogenic aspect of clenbuterol, while sometimes overestimated due to the high CNS stimulation that yields a "wired" feeling, can vary according to prior exposure to various amphetamine-like compounds and certainly is not much greater than that of ECA. DNP does not have the anorectic effects of ephedrine or other thermogenic agents; rather, it tends to increase hunger, particularly appetite for carbohydrates. This problem is easily solved with appetite suppressants, and one may even use ECA itself for this purpose while on DNP.
Molecular Basis for Efficacy
DNP accomplishes the astounding boost in metabolic rate via inhibition of the F0F1 ATP synthase molecule, located in the inner wall of each mitochondrion. While the electron transport chain still functions to pump hydrogen ions into the intermembrane space, the coupling of the proton gradient to ATP production is rendered impossible by DNP. As a result, ATP production is dramatically reduced, and the energy is instead thrown off as heat. This results in an astounding production of heat; when using dinitrophenol, the athlete will radiate so much heat that it is uncomfortable to be within any proximity of them. Luckily, this heat does not fully contribute to body temperature increases, and is instead thrown off from the entire body surface, particularly the head. As a result, adequate doses of DNP will usually only elevate body temperature by about 1-1.5ºC. This is a good thing for your central nervous system and other delicate tissues; if the heat produced by ATP contributed in a more direct matter to body temperature, effective doses for fat loss would cause supraphysiological body temperature increases on a level unwitnessed at this time. Nonetheless, overheating is a very real danger; this and other side effects shall now be addressed
