Injections changing over to drops.

Hi, I'm new to this forum. I just started the hcg injections that I bought from a doctor in town, then found the hcg 2.0 so I've just ordered the drops and I'm wondering if the drops have the same value as the injections. I started out with 63 lbs to lose with 50 lbs left at this point. I draw to the 25 line into the syringe, I'm not sure what that is in i.u. Any suggestions?
