1st injection went okish, I inserted the needle slowly aspirated and drew blood, pulled out, changed needles inserted needle and drew blood again! WTF! hard to believe any of you guys that don't aspirate live long! Anyway I swapped needles again inserted and this time injected, I'll be honest I was shitting myself as I've never injected a substance I brewed myself, everything else has always been medically prescribed this was sent from China in a dodgy looking envelope, brewed in my kitchen over a cooking hob and filtered with a caulking gun brought from a hardware store
