how many times have you taken it?,
just watch it make sure your not building up some sort or allergy to it, if the next time is worse diff breathing and such primatine mist would help,
Its enanthate so its not fast acting. so its only been in me for 2 days, but i take another shot today. Ill see if anything like it happens again tonight or tmr or the next couple days. I havent gotten them today at all.
