hey i have a question regarding the hcg shot. I took my first shot today and with my bottle each .1 ml is 200iu hcg. i am planning on taking 250 twice a week. So i measure out exactly 250 iu and injected. after i pushed syringe all the weay through I took it out and retracted to plunger to check if there was any left in. There was half of a a little less then 100 iu of liquid in there. Is this normal? it definitely was in all the way. There Nipro syringes. should i mix more on my next shot to account for what is lost? or is that liquid some other substance from injection?
