    Well, I've recently become interested in DNP again. I did however just find this on the internet:


    Dinitrophenol (2,4-Dinitrophenol, DNP)

    Common Name: 2,4-Dinitrophenol
    CAS Number: 51-28-5
    DOT Number: UN 1320
    Date: July, 1989


    2,4-Dinitrophenol can effect you when breathed in and by passing through your skin.
    2,4-Dinitrophenol can cause reproductive damage. Handle with extreme caution.
    2,4-Dinitrophenol is a FLAMMABLE LIQUID and a FIRE HAZARD.
    Contact can irritate the skin. Long term exposure may cause dermatitis.
    2,4-Dinitrophenol can irritate the eyes, and may cause clouding of the eye lenses (cataracts).
    Breathing 2,4-Dinitrophenol can irritate the nose and throat.
    High or repeated exposure can affect the nervous system causing nausea, vomiting, abdominal pain, convulsions and even death.
    2,4-Dinitrophenol may damage the liver and kidneys.
    2,4-Dinitrophenol is a yellow crystalline (sand-like) solid but is often found in a solution. It is used in dyes, photo developers, explosives, and as a preservative of lumber.

    2,4-Dinitrophenol is on the Hazardous Substance List because it is cited by EPA and DOT.

    Exposure to hazardous substances should be routinely evaluated. This may include collecting personal and area air samples. You can obtain copies of sampling results from your employer. You have a legal right to this information under OSHA 1910.20.
    If you think you are experiencing any work-related health problems, see a doctor trained to recognize occupational diseases. Take this Fact Sheet with you.
    No occupational exposure limits have been established for 2,4- Dinitrophenol. This does not mean that this substance is not harmful. Safe work practices should always be followed.
    It should be recognized that 2,4-Dinitrophenol can be absorbed through your skin, thereby increasing your exposure.

    2,4-Dinitrophenol may be a teratogen in humans. All contact with this chemical should be reduced to the lowest possible level.

    Where possible, enclose operations and use local exhaust ventilation at the site of chemical release. If local exhaust ventilation or enclosure is not used, respirators should be worn.
    Post hazard and warning information in the work area. In addition, as part of an ongoing education and training effort, communicate all information on the health and safety hazards of 2,4-Dinitrophenol to potentially exposed workers.
    Wear protective work clothing.
    Wash thoroughly immediately after exposure to 2,4- Dinitrophenol and at the end of the workshift.
    This Fact Sheet is a summary source of information of all potential and most severe health hazards that may result from exposure. Duration of exposure, concentration of the substance and other factors will affect your susceptibility to any of the potential effects described below.



    Acute Health Effects
    The following acute (short-term) health effects may occur immediately or shortly after exposure to 2,4-Dinitrophenol:

    2,4-Dinitrophenol can irritate the skin and eyes.
    Breathing 2,4-Dinitrophenol can irritate the nose and throat.
    Exposure to 2,4-Dinitrophenol cause fatigue, thirst, sweating, headache and weakness. It may also cause anxiety and excitement.
    Chronic Health Effects
    The following chronic (long-term) health effects can occur at some time after exposure to 2,4-Dinitrophenol and can last for months or years:
    Cancer Hazard

    2,4-Dinitrophenol may cause mutations (genetic changes) in living cells. Whether or not it poses a cancer or reproductive hazard needs further study.
    2,4-Dinitrophenol has not been tested for its ability to cause cancer in animals.
    Reproductive Hazard

    2,4-Dinitrophenol may damage the developing fetus.
    2,4-Dinitrophenol has not been tested for its ability to adversely affect reproduction.
    Other Long-Term Effects

    Exposure to 2,4-Dinitrophenol can cause dermatitis. Clouding of the eye lenses (cataracts) may occur after a long exposure.
    High or repeated exposure can effect the nervous system causing nausea, vomiting, diarrhea, abdominal pain, headache, anxiety, weakness, convulsions and even death.
    2,4-Dinitrophenol may damage the liver and kidneys.
    Medical Testing
    If symptoms develop or overexposure is suspected, the following may be useful:

    Liver and kidney function tests.
    Exam of the eyes.
    Evaluation by a qualified allergist, including careful exposure history and special testing, may help diagnose skin allergy.
    Any evaluation should include a careful history of past and present symptoms with an exam. Medical tests that look for damage already done are not a substitute for controlling exposure.
    Request copies of your medical testing. You have a legal right to this information under OSHA 1910.20.

    Unless a less toxic chemical can be substituted for a hazardous substance, ENGINEERING CONTROLS are the most effective way of reducing exposure. The best protection is to enclose operations and/or provide local exhaust ventilation at the site of chemical release. Isolating operations can also reduce exposure. Using respirators or protective equipment is less effective than the controls mentioned above, but is sometimes necessary.

    In evaluating the controls present in your workplace, consider: (1) how hazardous the substance is, (2) how much of the substance is released into the workplace and (3) whether harmful skin or eye contact could occur. Special controls should be in place for highly toxic chemicals or when significant skin, eye, or breathing exposures are possible.

    In addition, the following control are recommended:

    Where possible, automatically transfer 2,4-Dinitrophenol from drums or other storage containers to process containers.
    Before entering a confined space where 2,4-Dinitrophenol may be present, check to make sure that an explosive concentration does not exist.
    Good WORK PRACTICES can help to reduce hazardous exposures. The following work practices are recommended:

    Workers whose clothing has been contaminated by 2,4- Dinitrophenol should change into clean clothing promptly.
    Contaminated work clothes should be laundered by individuals who have been informed of the hazards of exposure to 2,4- Dinitrophenol.
    Eye wash fountains should be provided in the immediate work area for emergency use.
    If there is the possibility of skin exposure, emergency shower facilities should be provided.
    On skin contact with 2,4-Dinitrophenol, immediately wash or shower to remove the chemical. At the end of the workshift, wash any areas of the body that may have contacted 2,4- Dinitrophenol, whether or not known skin contact has occurred.
    Do not eat, smoke, or drink where 2,4-Dinitrophenol is handled, processed, or stored, since the chemical can be swallowed. Wash hands carefully before eating or smoking.
    For dust powder use a vacuum or a wet method to reduce dust during clean-up. DO NOT DRY SWEEP.
    WORKPLACE CONTROLS ARE BETTER THAN PERSONAL PROTECTIVE EQUIPMENT. However, for some jobs (such as outside work, confined space entry, jobs done only once in a while, or jobs done while workplace controls are being installed), personal protective equipment may be appropriate.
    The following recommendations are only guidelines and may not apply to every situation.


    Avoid skin contact with 2,4-Dinitrophenol. Wear protective gloves and clothing. Safety equipment suppliers/manufacturers can provide recommendations on the most protective glove/clothing material for your operation.
    All protective clothing (suites, gloves, footwear, headgear) should be clean, available each day, and put on before work.
    Eye Protection

    Wear splash-proof chemical goggles and face shield when working with liquid, unless full facepiece respiratory protection is worn.
    Wear dust-proof goggles and face shield when working with powders or dust, unless full facepiece respiratory protection is worn.
    Respiratory Protection
    Such equipment should only be used if the employer has a written program that takes into account workplace conditions, requirements for worker training, respirator fit testing and medical exams, as described in OSHA 1910.134.

    Engineering controls must be effective to ensure that exposure to 2,4-Dinitrophenol does not occur.
    Where the potential exists for exposure to 2,4-Dinitrophenol, use a MSHA/NIOSH approved supplied-air respirator with a full facepiece operated in the positive pressure mode or with a full facepiece, hood, or helmet in the continuous flow mode, or use a MSHA/NIOSH approved self-contained breathing apparatus with a full facepiece operated in pressure-demand or other positive pressure mode.

    If employees are expected to fight fires, they must be trained and equipped as stated in OSHA 1910.156.
    If 2,4-Dinitrophenol is spilled or leaked, take the following steps:

    Restrict persons not wearing protective equipment from area of spill or leak until clean-up is complete.
    Remove all ignition sources.
    Ventilate area after clean-up is complete.
    Collect powdered material in the most convenient and safe manner and deposit in sealed containers.
    Keep 2,4-Dinitrophenol out of a confined space, such as a sewer, because of the possibility of an explosion, unless the sewer is designed to prevent the build-up of explosive concentrations.
    It may be necessary to contain and dispose of 2,4- Dinitrophenol as a HAZARDOUS WASTE. Contact your Department of Environmental Protection (DEP) or your regional office of the federal Environmental Protection Agency (EPA) for specific recommendations.
    FOR LARGE SPILLS AND FIRES call your fire department immediately.

    Prior to working with 2,4-Dinitrophenol you should be trained on its proper handling and storage.
    Keep 2,4-Dinitrophenol wet or treat it as an explosive. Dried out material may explode if exposed to heat, flame or shock.

    2,4-Dinitrophenol is a yellowish crystalline solid and is the most important of the six possible dinitrophenol forms. It is used mostly as an intermediate to make dyes, photochemicals, pest control agents, wood preservatives, and explosives. It may enter the environment from industrial discharges, spills, or possibly as a breakdown product of certain pesticides containing 2,4- Dinitrophenol moieties.


    Acute toxic effects may include the death of animals, birds, or fish, and death or low growth rate in plants. Acute effects are seen two to four days after animals or plants come in contact with a toxic chemical substance.

    2,4-Dinitrophenol has high acute toxicity to aquatic life and to birds. Insufficient data are available to evaluate or predict the short-term effects of 2,4-Dinitrophenol to plants or land animals.


    Chronic toxic effects may include shortened lifespan, reproductive problems, lower fertility, and changes in appearance or behavior. Chronic effects can be seen long after first exposure(s) to a toxic chemical.

    2,4-Dinitrophenol has moderate chronic toxicity to aquatic life. Insufficient data are available to evaluate or predict the long- term effects of 2,4-Dinitrophenol to plants, birds, or land animals.


    2,4-Dinitrophenol is moderately soluble in water. Concentrations of between 1 to 1,000 milligrams will mix with a liter of water.


    2,4-Dinitrophenol is slightly persistent in water, with a half-life of between 2 to 20 days. The half-life of a pollutant is the amount of time it takes for one-half of the chemical to be degraded. About 98.75% of 2,4-Dinitrophenol will eventually end up in water; about 0.65% will end up in terrestrial soil; and about 0.6% will end up in aquatic sediments.


    Some substances increase in concentration, or bioaccumulate, in living organisms as they breathe contaminated air, drink contaminated water, or eat contaminated food. These chemicals can become concentrated in the tissues and internal organs of animals and humans.

    The concentration of 2,4-Dinitrophenol found in fish tissues is expected to be somewhat higher than the average concentration of 2,4-Dinitrophenol in the water from which the fish was taken. SUPPORT DOCUMENT: AQUIRE Database, ERL-Duluth, U.S.EPA.

    Hopefully some ppl r gonna reassure me that all of the above is just bs...
  5. Heretic

    Heretic Member

    No, it's not BS, but you have to take it in context. DNP is labeled as a poison for handling and transportation purposes because it can cause nausea and sweating, which are definitions of a poison. The powder, when dried, is extremely flammable and must be specially handled and transported, another reason why it has an MSDS. Have you ever drank a beer or smoked a cigarette? Did you read the warnings on the side? Did that stop you? Hell no, because you realize that taken to an extreme both can be harmful, but used in moderation the risks are minimal.
    Don't get it in your eyes, don't inject it, don't snort it, and don't go over the usual dose of 5mg/kg body weight unless you are experienced it. If you bother to read the article I posted you will see plenty of links to studies done on humans and animals showing that DNP can be used safely and effectively for fat loss in humans, and in fact that it maybe safer than clen, T-3, or ECA

    OK, I read somewhere on here that it is advised not to be used when using anti-depressents. I am using lexapro right now and was interested in some DNP. Is this not advised because it can physically harm you or because you are so down while on dnp???
  7. Heretic

    Heretic Member

    I've never seen any advice about not taking anti-d's while on DNP. DNP has no effect on mood, physically it makes you lethargic and tired, but it's not an upper or a downer or anything. If it helps at all I've never heard of any complaints or problems. Obviously don't drink or do rec drugs while on it, I don't think I'd even use valium or vicodin just to be safe.
  8. LightWeightBaby!

    LightWeightBaby! Junior Member

    I did read the stuff you posted, it's just I found the above info as well. But yeah I wouldn't let it put me off, I mean, shit, like you said, everything has risks, especially if not used properly.

    BTW Heretic, I emailed you about the possibility of obtaining some DNP. Did you get my email?

    hey heretic, how long do you think DNP would keep adequate potentcy if is is in a dark glass container in a cool dry place? These are your caps.

    Great post HH!!

    Quick question (For Harry or anybody else with info)...does DNP make you more sensitive to UV rays?

  13. Heretic

    Heretic Member

    Back up!
    I've heard of people having DNP for over 6 months and still using it no problem, so I think it keeps just fine as long as it's away from light/moisture.
    I can't think of any reason DNP would make you more sensitive to UV, but I would take it easy first to make sure. My main concern would be keeping an eye out for not getting too hot. I think I've tanned on it before no prob.

    Hi LWB, Im assuming this is lightweight from AR. Nice to see familiar names. Didnt know you were here also.

    I just finished a DNP cycle. Lost 8 pounds in 10days. I started out at 200mg caps first 2 days then upped it to 400mg spreading it out one cap in the day and one at night. I bought 50 of them. Works really well. Sweat a lot and was tired but worth the experiment. Now Im trimming down a bit from the bloat and I cant wait to see how that looks.

    Very informational post indeed. For others to read I wanted to share my experience with DNP so others can gain more confidence in the use if properly used without abuse.

    I did much much research before I even bought the stuff and this is very important. Hate when people jump on stuff without researching the product first.

    I carb depleted tapering down 3 days out before first day of DNP to get the extra advantage of the DNP (probably not necessary). I still trained but of course you are very lethargic so training was a minimal. I also took the following supps while on it.

    ALA 2XED
    Multi-E 2xED
    Vitamin C 1gram ED
    Vitamin E 1gram ED
    Milk Thistle 600mg
    Flax Seed Oil 1000mg 2xED
    V8 juice through out the day
    Cup of oatmeal and scoop of protein and peanut butter every morning.
    White/Brown rice along with Chicken Breast and half cup of veggies every meal. Tapering off carbs towards the night. Of course 1 Gallon of distilled water through out the day. Took my temp consistantly to watch out. I reached up to 100 degree's and stayed there by third day.

    I've seen others add more to this but this seemed ok for me. I had no problems on DNP besides sweating a lot. Kept the fan on me at night and heat down. I have air at work but its never hot there anyways.

    Hope this adds to the thread. LMR

    has anyone tried longer (e.g. 3-6 week) cycles of low-dose DNP?

    Seems like DNP always comes in 200mg capsules. Couldn't a user re-package them into (approx) 100mg doses by buying empty gel capsules and splitting the doses?

    Any thoughts on this? I've heard that DNP *powder* can be really irritating to the throat, so I'm assuming you'd have to be super careful about this. Also, do people recommend having Benedryl around for the first couple doses?

    Peace Division Junior Member

    Unless you have access to a hood, I wouldn't attempt "recapsuling" to make a smaller dose. The DNP will probably get everywhere, and stain everything it touches, after a while even your hands when wearing nitriles.

    It would be nice to have 100mg caps, so this way one could bump up to 300mg and not 400mg etc., etc. And I would have some Benadryl around as PL stated on the first few pages of this thread, and take it AFTER you have stopped taking the DNP. Peace.

    I believe Huck from EF did a 42 day low-dose DNP cycle (6 weeks), he had some real skin problems by the end of it though. DNP causes a histamine release apparently, and over time this can build up to the point of causing hives/rash, which is why you always want to take benadryl or Quercetin with it (another reason why my Generation II caps have 200mg Quercetin in them). Don't wait until you get a rash to take it, just take it anyway. It doesn't happen to most people, and not always the first cycle either, but just be careful. I've heard of people taking 1 200mg cap every 3rd day (DNP's halflife is 36-48 hours I believe) so that they keep it in their system but don't let it build up too much, but I think this is mostly used by women. It could be a way to cycle it longer though.
    I am looking into making 100mg caps, problem is that the price would be the same as the 200mg caps, so I don't see why anyone would buy them. You have to undestand that the powder itself isn't very expensive, what you're paying me for are the risks I take and the BITCH that is to handle and encapsulate DNP. My risks and labor are the same whether it's 100mg or 200mg, so the price would be the same as well.

    wasp Junior Member

    was wondering if i could just stay on 200mg cycles instead of bumping up to 400mg,and still get good results, im just interested in losing fat gradually, not 20lbs in a month type of speed. anyways if im way off base let me know cuz i got some of heretics stuff on the way.
