I've done 3 100mg this week now and it went like this. Right leg , 23g terumo didn't feel a thing. Left leg 23 terumo a little sore going in. Then right leg again , I tried a 25g BD , it took alot to get it to pop the skin and so sore a 1/4" in I had to pull it. So I used a 23g terumo again up higher and in was fine. Are the BD that bad or did I just do something wrong. I even let the test p run down the needle
