Yeah bro, I've increased slowly over the last year and a bit of tren blasts, bit more each time and played around with my test dose too, but yes I find as long as my estro is in 

 my prolactin/progesterone stays in 

 as well. 
Liver values have minimally jumped out of range at times but as I've said before I attribute that to the orals not the tren. 
Only sides for me on high dose tren, is insomnia (bad) and lethargy and my acne gets a bit worse on my back
