SWIM did a test 90 minutes ago. He took a full San Pedro alkaloid extract and removed the non-mescaline alkaloids from it by washing the mescaline hydrochloride with acetone a few times followed by 99% isopropyl alcohol. He took the combined washes and evaporated them.
The alkaloids that were washed off the mescaline were very sticky once dry. He added calcium carbonate to it and mixed it a little to help make it less sticky. This trick works really well. He was able to get it to a powdery state that could easily be measured.
He calculated what a 25 mg dose of extract would be by adjusting for it being diluted with calcium carbonate.
11:00 pm, he took 25 mg of the alkaloids orally without any water. He wanted to see what it tasted like. It was extremely bitter and difficult to describe. It almost immediately made his mouth numb.
11:20 pm, his mouth was much more numb. He felt a pleasant tingling sensation in his body that's similar to THH. He felt somehow different but there were no visual effects. It was a smooth and pleasant sort of soft feeling. It felt like it might become psychedelic if the dose was stronger.
12:00 am, his tongue was still numb. He still felt a pleasant tingling sensation. There were no visuals, but things sort of looked animated.
12:30 am, the effects are starting to fade but are still present. His tongue is still slightly numb.
1:00 am, the effects got stronger again, sort of a second wave. He feels more body tingling sensations, some euphoria. His tongue is still numb a little tiny bit. Maybe some was absorbed sublingually and that's why there's a second peak? The effects are the same though and nothing at all like mescaline, more like 300 mg of THH orally.
The overall experience was pleasant. There was mild euphoria at times and it seemed to be on the verge of becoming psychedelic. Next time he will try a larger dose and see what happens.
