Hi,
Im about to start taking HCG on days 5 and 6 and T shots on the 7th day. My question is I get 500iu amps of hcg. Am I able to draw the 500iu out of the amps, inject 250iu on day5 and then leave the remaining 250iu in the needle in the fridge for the next days shot ? Is this safe ? I will change the tip with a new one when its time to inject again.
