Online ur only going to find opinions, this is not an exact science. When u go to the doctor they throw the pin in u like its a dart and just shoot it in without a thought. Sure u can mess up but i have never had a problem and i have no idea how many hundreds of shots ive done. Stop looking for the easy way by taking all these tabs that are harsh on ur liver. When u click on the forums site the first thing u see is a pic of a needle, that should give u a clue. Fear is in ur head. Ull be cool, there is a good site that i can reccomend that shows u where to stick the shots. I dont know if i can list sites on this board though. As for a stack, I would just do more reading and try to filter out all the bs out there. Cyp or Enth are essential or maybe some blend like sust or duratest. From there its all opinions on peoples experiences.
