cycle questions for 48 yr old

hey guys



im looking to start a cycle up in a couple of months and I was looking for a little advice.



my stats



im 48

5'9"

185-190 lbs

12%bf

I have trained and lifted weights most of my life.



I have run three cycles of tren in the past along with sust and mas and have done pretty well on ot with the exception of having a really hard time with prolactin.



im wanting to run something to add a little mass while at the same time not kill my ability to compete in some endurance events.



any stack advice would be greatly appreciated.



thanks in advance
