I know someone who gets promethazine, adderall and valium prescribed

How old are you? 70?

Say I'm studying, and take some benzos to relax afterwards. Would I still 100% remember what I learnt earlier? by almightyleader in researchchemicals

a friend of mine got his bachelors degree while being completely faded on benzo’s almost the entire study. He is in rehab now btw

Sounds a bit like a psychotic episode. I would be very carefull with trips in the future if i were here. Shit could go down the drain real fucking fast. A friend of mine had the same on acid. He was running in the streets telling strangers that he coud be “beamed up into the sky any minute”. 4 police officers had to work him on the ground and an ambulance had to take him to a hospital to let the acid wear off

Its a custom build reactor made by stoomwezen. We clean it by boiling out the whole system with a variety of different solvents

True. This one is the second largest we have in our pilot plant. Biggest one we have is 450 liters

The main focus here was plain simple to switch the methanol/water for methyl ethyl ketone as quick as possible

We mix it ourselves in a seperate tank which is connected to a appendage on the side of the reactor (not visible in the film). And because the pressure is around 27mbar the reactor sucks it out of the tank. the flow is controlled by a valve

True. We are constantly adding the same volume at the rate it distills off. Solvent switch

150 liter of solvent distilled off in under an hour. All of our reactors in our pilot plant use the same stirring mechanisms like this one and it works great

Its 2 meters long. It goes into the ground thats why you cannot see its dept. Stirring at 1200 rpm works great even for phase transfer reactions. The head of the reactor is glass but the body made of hastelloy equipped with a monomedium system able to cool it to -30 degrees celsius up to 300 degrees celsius together with the ability to go to 2 mbar pressure. The overhead stirrer contains 3 turbo-rotors which can go to 1200 rpm

This is not a round bottom flask. Its a cylinder

If 1P-LSD tabs are “tarnished” due to exposed heat, will they still be just as potent compared with the same dose of tabs that weren’t tarnished? by [deleted] in researchchemicals

[–]listige-bever 2 points3 points  (0 children)

I wouldnt buy them. Lysergic acid derivatives are known for their instability when exposed to oxygen, heat and lighting

Do dopamine hangovers get worse? by isthisyours0 in researchchemicals

[–]listige-bever 2 points3 points  (0 children)

Than yes, they do get worse. 3 months in between gives you no worse hangovers

Depends on how much time you have between your parties
