I used the pods from that site for the better part of 8 years, they're excellent. Very potent, the high is very long lasting. In terms of value, you get a lot of bang for your buck. Beware however, the withdrawal is very long and protracted and quite intense. The acute withdrawal lasts for about 7-10 days and you'll lingering withdrawal symptoms for another 1 to 2 weeks after that, then PAWS sets in. I don't know for how long as I never made it more than a week or 2 past the acute phase, but judging from the other WD symptoms, it'll be long. At the start 15-20 grams crushed to a powder in a blender with hot water and lemon juice, then blended and left to steep for an hour then filtered got me high as shit for a solid 24 hours. I'd wake the next day still pretty high. I felt like I'd found God. I had been doing codeine before this and whilst it was great, this was a whole other beast. I worked my way up to 120gram doses, sometimes with a 60gram booster 12 hours after the 1st.
I wanted to get on methadone to get off it, but none of the drug workers, nurses or Drs would do that because I "wasn't on heroin, so it wasn't indicated, just stop taking them" Well I did then get on heroin and starting injecting very quickly and did that for a good 6 years too, before I finally got on methadone. I've not used in 3 years now. Honestly heroin WD is miserable, but poppy pod tea is worse IMO, because it's as intense/acute as H but lasts much longer. Just be aware if you ever wanna get off pods, you might get very little support from your doctor or drug team, as it's a relatively unknown drug.
