Nothing to worry about man, happens all the time. As for the pain try these:
1) Sit in a hot tub
2) Get a hot towel and rub it
3) Get a massager and rub the site for a good 20 minutes
All in all you are stuck with the pain for atleast this week. Try doing these things right after the shot and it should help decrease the pain. Oh yeah you could also mix whatever it is you are taking with some Eq.
A hot pad helps too. I have to do this sometimes when I hit veins or go im by accedent with my insulin...go in 20 min intervals till it starts to feel better.
Its because of the sust that shit is the most painfull AS i have ever used. Just deal with the pain and watch how great the results are that you'll get. By the way why are you doing it twice a week? Just do it all in one shot unless your doing high doseages. Sust does not need to be done more than once a week.
Massage the area after your injection and take a warm bath or shower and that may help with it. Also mixing Eq or Deca in the same syringe dampen the pain a little
Im going with 500mg a week and was told by one of our new MODS that it would be best to do it twice a week to keep the levels of test at the same point through the week.
