no need for karma, but as far as the ttokkyo winny, i wasn't too impressed, especially when i only used zambons in the past. I used 100mgs eod ttokkyo, and felt i got better results at half that dosage with zambons. but for the price, it's a steal.
just make sure you draw it out with a large guage needle and mix it with some bacteriostatic water in the syringe, then you can change to a smaller guage for injection. The water helps thin it out to avoid clogging.
