I have been using test 400 for a 2 weeks now and am using a 22G 1.5 PIN. The day i do it, its fine doesn't swell or hurt. The second day, it forms a bump and hurts a little. The third day it is a huge welt and hurts. I put the test in my buttocks. Can you please advise if I am not doing this correctly, also can you tell me if this is normal. Any advice is great.
Thanks
