Okay, If you are on pills and your blood work shows that you have X amount of E in your system. You should theoretically get the same results as if you were on injections and your blood work shows that you have the same X amount of E in your system. E is E theoretically and it "should" not matter where you get it from. You hear people who claim to have better results from one or the other, but, what those claims lack and really can not prove one way or the other is, that what if you had not switched from one form or the other. How do you know you would not have still achieved the same results? Maybe it was just time for you body to respond in that way to the E and it wouldn't have mattered if you were on pills or injections. The end results would have been the same.
The fact is, we just don't know if one is "better" than the other from a results point of view. People claim better results from both and people claim 0 results from both. Another problem with it is, How do you quantify results? It's not something that you can put a number to or measure. Everyone has their own ideas of what "results" are. Maybe what you are feeling is nothing more than a placebo effect based on a biased idea that one is better than the other.
I'm not saying that one isn't better than they other. One may very well be better. I'm considering doing both injections bi weekly and a pill daily. Seems to me that might be the best way to go. If one happens to be better than the other, then you got the grounds covered. Sorta the way I feel about taking progesterone. There is no evidence that it helps in any way, but there is reason to believe it can help with breast development so I figured, it can't hurt and if there is even a small chance it will yield better results, go for it.
