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
