Are you currently on TRT? Get your bloods done before you start, you’ll regret it later if you don’t know your baseline bloods. Everyone aromatizes differently, especially depending on how much body fat you currently have. No reason to immediately jump to 500mg test and 400mg EQ for 12 weeks, you will have no idea what your tolerance levels are at each dose for sides, and you’ll damage your health when you could have cut your dosages in half and run it for twice as long and get way better results and maintain better health. If you want to start a blast off rip and not be smart about it, then I’d run 400 Test and 200 EQ and assess your bloods and side effects 6 weeks in. Smarter approach would just start with 300 test and when gains slow after a month or 2 bump it up another 50-100mg until E2 climbs and then you toss in EQ to help with E2 and further increase anabolism. Run a high dose 12 week cycle, and then come off and run pct and you will be lucky to keep half the gains you made. Run a low cycle for 6mo that you slowly titrate up and you will keep immensely more gains. Rome wasn’t built in a day
