Propylhexedrine HCl 

Propylhexedrine HCl is the HCl (Hydrochloride) salt of Propylhexedrine. While freebase Propylhexedrine is a liquid, Propylhexedrine HCl is a solid white salt. Propylhexedrine is made by dissolving it in ethanol and bubbling HCl gas through it. Propylhexedrine is good as a pre-workout, to unclog the nose, and to reduce hunger for weight loss. It is 1/4 the strength of amphetamine, and releases dopamine, norepinephrine, adrenaline (causes vasocontriction), and serotonin. It activates TAAR1 receptors. The dose range is 60mg to 250mg+. Doses of 60mg to 180mg will give you energy, concentration, an urge to lift things and run a lot (adrenaline rush), and more. Doses of 250mg or higher will lead to a buzz (mild to moderate mood boost) to a high (high mood boost), an even greater adrenaline rush, and increased side effects such as anxiety in most, fatigue, anger in some, insomnia, sweating, headaches in some, and more. Stacking Propylhexedrine with CBD and 7,8-Dihydroxyflavone (Tropoflavin) prevents some side effects.

Propylhexedrine HCl is obtained by acid salting Propylhexedrine freebase dissolved in 50% Ethanol and 50% 2-methyl-2-butanol cooled down to -10°C by bubbling HCl gas through it. There's 175mg of freebase Propylhexedrine and 216mg of Propylhexedrine HCl can be obtained. Propylhexedrine freebase can be cleaned with 0.4ml to 1.0ml of Muriatic Acid (40% HCl Acid) per cotton in 5ml of water per cotton and washed with 15ml of water per cotton for a total of 20.4ml to 21ml of solution per cotton. Then clean it from Lavender oil and Menthol using 10ml to 20ml Hexanes (Charcoal Lighter Fluid). Shake it in a bottle and separate layers. Then clean it with 10ml to 20ml of n-Pentane per cotton. Separate layers. Add 10ml of Vodka (40% ethanol) per cotton. Evaporate most of it in a Bovado Borosilicate Glass cooking dish. Then wait until the liquid starts to get kind of viscous and put it in the freezer and/or use a fan to get Propylhexedrine HCl crystals. Scrape with a Razor and weigh it.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
