Trt with Blast Test Cyp and Eq Input

Background:
28 years old been lifting for 10years. 5’7" 170lbs 8-10% bf. I’ve been on trt and will be for life. My current dosage is 90mg test cyp 2x/week along with 250iu hcg 2x/week. Total 180mg test cyp and 500iu hcg per week. I’m thinking about adding another 120mg test 400mg eq and 1mg arimidex for 10 weeks and then cruising back to my normal 180mg of test cyp and 500iu of hcg. Just looking for any input or variation of dosage anyone has to offer. Thanks

Anyone? Just looking for some help or advice.
