I'm going to make this short and sweet since I'm not experienced with K. In fact, it was my first experience. So I have nothing to compare it to. This was off Valhalla, though she's on others as well such as Alphabay.
Stealth - All I have to say is... LOL. I love it.
Product - Like I said, I have nothing to compare it to.. though, it kind of felt like nitrous at parts but I put that to the back of my mind because this was much more amazing. Anyways, I laid down with my eyes closed, and felt like I was flying through different worlds and dimensions. Almost like a vivid dream, sometimes I feel like I could control or alter. It was one of the most amazing things I've ever experienced and I actually feel like a happier person. I only did roughly 50mg lines at a time, sometimes more.
Communication - She's really cool and friendly. Told me everything I needed to know.
Shipping - It took 4 days and arrived on a Monday. Very happy. Might have taken 3 days if it weren't Sunday, who knows? It was quick.
Weight - 1.030g (.030 over)
Overall I would definitely recommend to go through her if you need K. I wish you all the best. Much love.
Did they come in big crystals and did you have to crush it up alot to get a fine powder? Never done the s isomer but the pics seem like it would burn like a bitch going up.
