What is Mephedrene?

Chemical Properties

Mephedrene is a stimulant which is a ring-substituted derivative of methiopropamine. It is not a substituted cathinone derivative like mephedrone, as it lacks a ketone group at the β position of the aliphatic side chain, but instead more closely resembles substituted amphetamines. It was first identified in Germany in June 2020.

Some of the most commonly reported effects are:

  • Stimulation
  • Empathy, love, and sociability enhancement
  • Focus enhancement
  • Thought acceleration
  • Analysis enhancement
  • Wakefulness
  • Memory enhancement
  • Motivation enhancement
  • Euphoria
  • Compulsive redosing
  • Increased music appreciation

Some of the potential side-effects include:

  • Increased heart rate
  • Dehydration
  • Appetite suppression
  • Nausea
  • Temporary erectile dysfunction
  • Increased perspiration
  • Nystagmus

  1. cialis without prescription

    This is a topic which is near to my heart… Take care!

    Where are your contact details though?

  2. Chiss-r (verified owner)

    Research proved mellowed and smooth results, not too overming but enjoyable! Subject wasn’t affected by craving, seems functional. It wouldn’t be recommended for hardcore researches, but more for lazy Sunday experimentations.

  3. Shulg (verified owner)

    Don’t know how to think about this chem.
    Mild stimulating, nice bodyhigh, physical effects are pleasent.
    But it lacks of something. Very more acting on SERT than DA/NE, so it’s a pretty mellow high. Mild euphoria at the dosages experienced.
    It’s require very high dosage for being quite interesting.
    Seems almost not active below 50mg.
    I think dosages should be more around 100mg+ range for working kinda good.
    The chem remind me a bit 3-MMA.
    Not a bad compound, but it is soooo expensive god.
    consedering the ratio dosage/effects.
    35e/G it far too high price.
    Please just lower the price.
    25e/G would be a far more adapted price and will make this chem more worthwhile.
    Not bad, but not a mind blowing stim.
    Anyways, love on you team CC 👌

  4. Le renard

    Not bad, euphoric stimulants with seeoroninergic properties. But imo is too much pricey for what is it. 20/25e should be a good price for this Chem.

  5. Sosalo4ka (verified owner)

    not bad,does not fuck your heart like like his father , but also there are almost no side effects, this one one is more chill euphoric, your bonsai will like it
