I just got my week 6 bloodwork back from my initial 250mg/week Test Cyp protocol (split Mon-Thu). Injections were done IM in the delts with a 29g ½" syringe, and bloods were drawn fasted on Thursday morning right before my pin to capture true trough levels. I skipped any AI (Arimidex) prophylactically as I wanted to avoid crashing my E2 and get a real sense of my aromatization rate plus any emerging sides. Toward the end of weeks 5-6 I did notice mild water retention and a day or two of itchy chest, but nothing major. Now that I have a clearer picture of my E2 response at 250mg/week, I'm planning to step up to my first blast at 500mg/week (split M-W-F) and add 0.5mg Arimidex 3x per week alongside my Test pins.

Questions for you guys:
- Do you think 500mg is a bit aggressive for a first blast, or is it a reasonable jump?
- Should I start the AI more conservatively at 0.5mg twice weekly and recheck bloods in 6 weeks?
