When I was on pills my E wouldn't get above 168 pg/ml. I've been on injections for 7 months now, and my E floats around 450 to 550 pg/ml. So for me injections work much better than the pills ever did or could.
I'm intersex tho and genetically female(female hermaphrodite) so my genetics makes things more complicated for me at least. Having said that, In my observations of friends on this website and others the injections tend to yield better results, and are liver friendly no matter whether your intersex , mtf, etc, etc, etc. As for myself and my well being, I know the injections are a better solution -IMHO that is.
