I did have some bad pip for the first couple of shots, but I have been adding half a ml of test suspension with it so yesterday I decided to leave the suspension out and yesterdays shot is pretty much pip free.so all seems good now..
( note the test suspension is from another lab not med tech) I will no for sure in the next few days if it was the suspension but it definitely seems that way.
as for results, I'm only 3 days in and not seeing anything as yet I feel my body temperature is up slightly, waiting for results.
