Need some advice/thoughts

I am 51 years old, 5'9" 182 as of this morning. I am normally about 10% BF of less. I am hitting the beach in June and want to make sure I am looking my best. Diet is spot on, I do cardio 5-6 days per week, I lift high rep, high sets with moderate weight due to very bad joint issues. I have been on TRT for 13 years and have had at least 20 cycles under my belt during that time. I mostly do Test/Tren-A heavy for 6-8 weeks and start with T-Bol for the first 4 weeks.

I can't do Tren anymore...
