MDPHP Review


Recently, the recreational drug landscape has changed, thanks to many new research chemicals. Among them is MDPHP, a stimulant that’s received interest and curiosity from users and researchers alike. In this comprehensive article, we’ll dive into the history, dosage, administration, effects, and potential side effects of MDPHP.

General Information on MDPHP

To begin this research chemical review, we’ll cover general information on this drug. MDPHP, or Methylenedioxy-α-pyrrolidinohexiophenone, is a synthetic stimulant in the cathinone class of chemicals. It’s closely related to the well-known α-PVP, also known as “flakka.” It’s a potent norepinephrine-dopamine reuptake inhibitor, supposedly responsible for its stimulating effects. The MDPHP research chemical is often sold in its freebase form as a yellowish-white crystalline powder. Users can consume it in many ways, including through oral ingestion, nasal insufflation, vaporization, and rectal administration. We’ll cover those methods in more detail below.

History of MDPHP

Next in our MDPHP review, we’ll explore this substance’s history. MDPHP first appeared in the scientific literature in the early 1960s when it was synthesized by chemists at the pharmaceutical company Boehringer Ingelheim. However, it didn’t become widespread as a recreational drug until the mid-2010s. During this time, MDPHP appeared as a legal option to more tightly regulated stimulants like methamphetamine and cocaine. Therefore, it earned the label of a “designer drug” while appealing to users looking for legal highs.

As with many research chemicals, the MDPHP research chemical has largely escaped regulation. Authorities often play catch-up as they try to control its distribution and use. The substance has been banned in some countries, such as the United Kingdom and Sweden. Others have enforced temporary bans or restrictions on its sale and possession. If you’re looking for legal drugs, be sure to check MDPHP’s status in your zone.

Despite being pretty new to the recreational drug scene, MDPHP already has a reputation for its potency and intense effects. People compare it to other powerful stimulants like MDPV and α-PVP. However, little is known about the long-term effects of MDPHP use. Today, it remains an experimental and potentially harmful substance.

Dosage and Administration

To use the MDPHP research chemical safely, you must know the right dosage and how to take it. In this section, we’ll discuss ways to use MDPHP, like swallowing, snorting, vaping, or rectal use. We’ll cover dosages and onset times for each method and highlight the pros and cons of each approach.

Oral Administration

MDPHP can be taken orally, either by dissolving the powder in a liquid or by placing it directly on the tongue and swallowing. A standard oral dose ranges from 5 to 15 milligrams, with onset times varying between 30 minutes to an hour. It’s essential to start with a low dose and gauge your body’s reaction before increasing the amount.

Nasal Insufflation

Another common method of administration is nasal insufflation or “snorting.” This method usually results in a faster onset of effects (10-20 minutes) and a more intense experience. Doses for nasal insufflation typically range from 3 to 10 milligrams, but it’s crucial to begin with a low dose to minimize the risk of negative side effects.


Vaporization, or “vaping,” involves heating the MDPHP powder until it turns into a vapor, which is then inhaled. This method provides a rapid onset of effects, usually within seconds to minutes, and an intense, short-lived high. Vaporized doses generally range from 5 to 10 milligrams, and caution should be exercised to avoid overheating and burning the substance.


Rectal administration, or using MDPHP as a suppository, is less common but provides a rapid onset of effects, similar to vaporization. Doses for rectal administration usually fall between 5 and 15 milligrams, and care should be taken to ensure proper hygiene and safety when using this method.


It’s not uncommon for users to redose MDPHP to prolong or intensify its effects. However, frequent redosing can lead to increased side effects, the development of tolerance, and a higher risk of addiction. It’s essential to exercise caution and give your body time to recover between doses.

User MDPHP Reviews

To understand the effects of a research chemical like MDPHP, there’s no better source of information than people who’ve experienced it first-hand. In this section, we’ll explore user reviews of MDPHP. We’ll look at the most commonly reported effects like focus, motivation, euphoria, and increased energy. By gaining insight into these personal accounts, we can better understand what users may expect when trying MDPHP for themselves.

Onset of Effects

Users report that the onset of effects from MDPHP varies depending on the method of administration, with vaporization and nasal insufflation providing the fastest onset (seconds to minutes) and oral ingestion taking longer (30 minutes to an hour).

Focus & Motivation

Many users describe a heightened sense of focus and motivation when using MDPHP, making them feel more productive and able to concentrate on tasks. However, this effect may diminish with repeated use or at higher doses.


Users often report experiencing a strong sense of euphoria, which contributes to the overall appeal of the MDPHP research chemical. The intensity of this euphoria can vary between individuals, and some may find it short-lived or not as pronounced as with other stimulants.

Increased Energy

MDPHP is commonly associated with a surge of energy, leaving users feeling more awake, alert, and physically active. This effect is especially pronounced at moderate doses but may taper off as the dose increases or with repeated use.

Anticlimax (“Comedown”)

The comedown from MDPHP can be quite harsh, with users often reporting fatigue, irritability, and depression. These negative effects can last for several hours or even days, depending on the dosage and frequency of use.

Potential Side Effects of MDPHP

As with any psychoactive substance, MDPHP use carries the risk of a range of side effects. These can range from mild and temporary to severe and long-lasting. Some common side effects reported by users include:

  • Increased heart rate
  • Elevated blood pressure
  • Insomnia
  • Anxiety
  • Paranoia
  • Sweating
  • Nausea
  • Teeth grinding (bruxism)
  • Muscle tension
  • Appetite suppression

More severe side effects, such as seizures, hallucinations, and aggression, have also been reported, particularly with high doses or frequent use. It’s critical to remember that everyone’s experience with MDPHP may differ, and individual reactions can be unpredictable. If you plan to use this drug, practice harm reduction techniques. Use it in the presence of a trusted friend and seek medical attention if necessary.
