  1. Straight Disso

    Posted by Mike on 25th Nov 2016

    Very much a straight dissociative. Can be challenging at higher doses. Great quality, great buy.

  2. Amazing Chemical...

    Posted by Dissociation on 11th Nov 2016

    My lab rats where in a deep trance state, could explain it as a ++++ from my observations...
    MY lab rat was seemingly floating around the room and enjoyed the state of samadhi... this happened with 3mg per kg...
    The Lab rat was cured from it´s previous traumatic state and began to realize what it has to do to stay healthy... stopped wanting to administer cannabinoids as well... a possible treatment for depression and trauma... i believe as well for PTSD.
    My rat is stronger then ever!

  3. Kinda like "k"

    Posted by Diaz on 29th Aug 2016

    Kinda like k but diffrent :3 Lab rats love it

  4. Awesome experience

    Posted by Jugo on 30th Jul 2016

    I have done an experience with 200mg because my rat is strong.
    He will remember all his life. The product is hight quality and very pure it was too much but it was awesome.
    The normal quantity is 100mg.

    And now it is difficult to find diphenidine now, a very good dissociative product.

    Thank you OBF ! :-)

  5. Quality Product, Quality Service

    Posted by Jade on 9th May 2016

    Very, very good quality diphenidine. Top notch product for clean and productive procedures. Best results between 70mg and 100mg orally (after fasting) with a smaller sized follow up an hour after the effects have blossomed. Listen to experienced researches and do NOT attempt heroic quantities, lest your test subjects become too fragile.

    As always, communication from the website is professional, friendly, and prompt.

  7. Careful with dosage amounts

    Posted by Study Coordinator on 27th Jun 2015

    I did not fully brief one of my formulations staff on the correct doseage for this reagent and he administered what I would call half a line to my three test subjects, quickly followed by full sized line. This was fine for my two male subjects, however when my femail subject came around from the dose she was not to impressed. But again she was not briefed fully on the study material.

    Two male test subjects who have tollerence to this type of compound really enjoyed it. The onset was strong to say the lease and the lab sustained some minor damage by the female rat loosing her footing (I generally clear the lab with these types of experiments, but forgot to move some crushed red vine based liquid in a conical flask which got split on the lab floor) but nothing the cleaners will not be able too sort out.
    I then had my test subject attempt the play the controversial video game GTA. Helicopter flight proved difficult but not impossible (one of my rats is an experienced pilot) and managed to take off from the airfield and took us all to the beach to watch the sun rise, most enjoyable.
    After the initial high, subjects levelled off quickly and very cleanly. Some were ready to continue the experiment with a second dose, but after the female subject put her foot down, the decision was made the call it a night.

    Very, very impressed and will use again, but with more experienced lab rats and controlled doseages.

    I would advise you clear the lab of breakables and consumable before conducting the experiment as this is really strong fucking shit.

  8. wow!

  9. 1st time review and purchase

    Lab rat experience exceeded expectations.

    Fast delivery and perfect communication.

  10. my best dangerous friend

    Posted by Unknown on 22nd Feb 2015

    Got a large ampint of this. Careful with quantities used as onset is steep but once the experiment was on its way, it was excellent. The local chemists will thoroughly enjoy this as a certain other compound is nay avaliable.
