Sorry for all of the questions lately. It seems that I am finding new things to obsess about these days. Anyway, I have always taken PIO in sesame oil. I do not have any allergic reactions and such to the PIO in sesame oil. Just the usual lumps and bruises. The nurse at my clinic suggested that I try Progesterone in Ethyl Oleate as it is easier to inject and people seem to have less issues with it. My question is this, is it just as effective as PIO in sesame oil? If it's not, I'd just assume stick with what I've always used. Have people had successful pregnancies with ethyl oleate? Were your P4 levels as good as they were with other forms of progesterone? Thanks.
