Continuing from the 'Nic in China' thread... A quick intro about the seller. He was certified to sell nicotine in December 2015 before the shipping regulations kicked in and he sells some gear as well as flavored nicotine juices in custom strength (from 1 to 30)... and most importantly, nicotine concentrate. If you want to deal with this seller, some basic Korean is required. I've been using Google and a Korean friend with some patience. If you want to order anything except the concentrate, you can do it through his Daum Cafe. You can use a Kakao ID to create a Daum account... and then you'll have to make a 등업신 청 post to agree to the TOS... so again, some Korean is required. I've been in Korea for 13 years and it took me 3 days to figure this out. But without approval, you won't be able to see much. And also, you might notice the word 'nicotine' is never mentioned it all... but what else could "60ml (10mg)" mean? Ha... It's definitely on the shady side of something. He sells 200mg in 50ml bottles and 100mg in 100ml bottle for 60,000 won and (includes delivery. But these can NOT be ordered through the cafe. You will need to contact him personally through Kakao Talk. He doesn't speak any English and I don't want to stress him out with that... I suspect I'm his only foreign customer and if I drive too many English-only waygookins his way he might get annoyed and blame me... so... PM me if you have Korean ability or a Korean who can help you (a lot). I may put your Korean (friend) to the test immediately since my own Korean friend who has been helping me out is often unavailable. I will not give details here about the seller, his cafe, or his Kakao Talk. I don't want to draw more attention than necessary to him and/or bother him. I found him purely by accident in a now-deleted Facebook post... PM me for my Kakao ID and we'll chat through there. As for my own buy, I got some 200mg in a 50ml bottle. It arrived in a basically-unmarked box in bubble-wrap and plumbers tape around the bottle like 5 times. Heh. It would have taken a steam-roller to expose the delivery man to any danger... but I admit that part worried me. The possibility of the 1 million won fine... is it real? Who gets it? -me or him? Anyways... I did the pH nicotine-strength test (using .12N Sulfuric Acid and Bromothymol Blue)... my test came out to 198.6mg for the 200mg concentrate. I haven't vaped it yet but I'm going to guess that impure nic would not come out so close. I didn't get such accuracy even with Hiliq. It does look it is water-based concentrate rather than PG... not sure if it matters at 200mg. It may be awhile until I vape it... so... anyone want to be a guinea pig? I may be able to meet up in Seoul... I'm not sure I want to risk delivery but I'll be in Seoul on some select days in the next few months.
