Primo E/Test E cycle opinions

Hey guys planning my third cycle, first was test e only at 500mg with zero issues. Second cycle was test e at 400mg and TBOL at 50 mg. For this cycle this was my plan

Week 1 500mg Test E/200mg Primo E

Week 2 500mg Test E/300mg Primo E

Week 3-10 500mg Test E/400mg Primo E

I understand that primo can crash E2 and since I have never used it I wanted the first two weeks to be lower doses to see how my body reacts instead of jumping in headfirst and crashing out. I look at this has a marathon not a sprint and would rather be safe than anything else.

Just got blood work back and everything is good to go on that end. Stats are 5’11” 191 lbs 10% BF 48 years old. After my cycle I am gonna cruise at 250mg test e. I am prescribed TRT but 250 is obviously above my prescription but since I am not coming off trt ever I am just gonna go with 250mg for my cruise.

I know some may advocate for a longer cycle but primo is expensive so trying to get the most bang for my buck. If you guys suggest running a longer cycle I am not opposed to it at all. But from my understanding it seems like 10-12 weeks of primo is pretty good.

Thank you for any advice guys.
