I'm not one for stimulants but having had untouched coke straight from the source, whatever the purity was when it left the country of origin is how we got when it arrived! There are several ways to know its as pure as it gets, 1. is through experience and 2. is by weighting on a .000mg or a .00 scale works also, and weighting between 30mg-50mg, since that is a dose that will get you fucked up if its uncut coke. We weighted on a mg scale the lowest dose as recomended in the case of pure coca, deciding to go with 30mg. Usually when we did coke our lines were just under a point (100mg), these lines were literally the size of toothpicks at 30mg per person.
After snorting 30mg, half in each nostril my friend & I both were overcome within 2-3min comeup period with an 'unusual' feeling of complete calm, serenity, euphoric & focused mindset. When I say calm I felt like 20mg oxy and extreme body relaxation as well as exhilaration of letting go of stress, empathogenic reminded me of the clean, calm high of MDMA but had to admit I liked it better as I was much more functional. Another 20mg after 15min and I could actually nod out if I wanted to close my eyes similar to MDMA it felt so relaxing, breathing felt orgasmic, and no figeting or physical stress or nervous ticks, euphoria maxed out! We did a few more lines and I went to sleep after laying in my bed and smoking 1-2 bowls, however long that takes, no problems the next day nor clogged nose though a psychological need was present for sure.
I dont go out looking for coke like the guy I was with but in my years of drug use I have only gotten this type of quality coke once, 1 time and it was around for about 4-5 months. Don't know much price wise as my friend was buying, I made the intro for them and didn't both asking, just remeber buddy was bitching there were deals only on 7g+ and a ball full price, also instead of the usual $80/g it was $100/g.
Also don't know how it should look or weather it should stick to the card those are last IMO, again this is b/c I didn't handle the coke everytime my buddy made the lines. Regarding scales it may be hard to get anything other than the .0 scales in which case measure as close to .1 and split as best you can in 4 lines/bumps. Also, this was the only time I ever bought coke with my own money once or twice, not more than 1 point though as I didn't have money. It was the first time after 50+ times doing coke that I could see myself addicted to it.....completley different from normal street coke that it may well be called something else, like heroin or dilaudid when injected as opposed to snorting honestly that different. Hope this helps!
