Don’t believe social media: DNP is not safe

What is DNP (dinitrophenol)?

DNP (dinitrophenol) is a chemical promoted for use as a weight loss agent as well as for body building. It has also been used as a pesticide and herbicide, as well as an intermediate in the production of explosives, dyes and, photographic chemicals. It is banned in the US. There is research on using low doses for overnutrition related diseases, neurodegenerative diseases (Alzheimer’s, Parkinson’s), TBI (traumatic brain injury), diabetes, and fatty liver.

Is DNP safe?

DNP is not safe. There is very little difference between a therapeutic dose and a toxic or lethal dose. Serious or fatal effects can occur even at low doses. There is no antidote.

Is DNP legal?

DNP is not legal, but the chemical is sold illegally on the internet. It is marketed to bodybuilders and for rapid weight loss. Brand names include Aldifen, Chemox, Dinosan, Dnoc, and Solfo Black.  

How does DNP work?

Normally, the body produces usable energy in the form of ATP in a process called oxidative phosphorylation. DNP interferes with ATP production by uncoupling (disrupting) oxidative phosphorylation. As a result, the body burns fats and carbohydrates very quickly, releasing energy as heat rather than forming ATP. This increases the metabolic rate, which is harmful to the cardiorespiratory system.

Can you overdose on DNP?

Yes, it is very easy to overdose on DNP. There is almost no difference between a treatment dose and a toxic or lethal dose.

Side effects and health risks of DNP

Side effects of DNP include headache, weakness, vomiting, lethargy, increased heart rate, increased respiratory rate, convulsions, and coma. Body temperature increases to dangerous levels resulting in organ failure and death. Sweating and dehydration also occur. Pulmonary edema, hemolysis (breakdown of red blood cells), and injury to the pancreas, liver, and kidneys can occur. Death is due to cardiovascular collapse or very high body temperature.

Chronic use of DNP can cause cataracts and glaucoma, dermatitis, peripheral neuropathy (numbness, weakness, pins and needles sensation), heart, liver and kidney dysfunction, and bone marrow suppression (decrease in white blood cells, aplastic anemia).

Does DNP interact with other medications or supplements?

Yes, DNP can interact with many medications and supplements.

When DNP is taken with stimulants such as caffeine, ephedrine, synephrine, and yohimbine, dangerous increases in heart rate and body temperature may occur. Seizures may also develop.

Although data are scant, when DNP and some anticonvulsants (such as phenobarbital, carbamazepine, or phenytoin) are taken together, the DNP may cause diminished seizure control or cause toxic levels of the anticonvulsant medication to accumulate in the body.

When taken with antidepressants, especially SSRIs (like Zoloft), SNRIs (like Effexor) and MAOIs (like Nardil), DNP can cause a fatal increase in body temperature, serotonin syndrome, low blood sugar, and organ damage.

If DNP is taken withaspirin or other salicylates, even more uncoupling of oxidative phosphorylation occurs and fatal hyperthermia can result.

Thyroid hormones interact with DNP to disrupt both metabolic regulation and the way the body uses the thyroid hormones. This can cause thyroid hormones to be deactivated and excreted from the body faster and also cause increased body temperature to dangerous levels.

When DNP is combined with alcohol, cardiovascular stress can increase, resulting in high heart rate, dehydration, organ failure and dangerously elevated temperature.

DNP marketing on social media: What to know

DNP is heavily marketed on social media including via forums, user testimonials, and private messaging channels. Fitness enthusiasts and bodybuilders are targeted with promises that DNP will maintain muscle mass while reducing body fat. People with eating disorders are targeted with promises that it will lead to rapid weight loss. It is falsely labeled as safe.

If someone swallows DNP, they should go to the emergency room immediately.
