I am ready for my first cycle and i've gathered so much information from this forum and related sites, and want to take a moment to say that everyone on here is so great and i apreciate all the knowledge and help

.
I'm 6ft, 21, 9% bf, 165 lbs., and have a fast metabolism. working out for 3 years, i know what i'm doing in the gym and am taking in 3,500k cal/day. I am looking to bulk up and gain as much mass as possible and keep as much after cycle. I came up with this:
FIRST CYCLE
Week 1: Frontload Test E 800 mg in one day( 800 mg, 400mg on each cheeck)
4.5 days later
Week 1-11:Test E-400 mg every 4.5 days (*reason 4.5 days explained below)
Week 1-4: Dianabol - 20mg a day... spread throughout day and after a meal.
Week 1-4: Arimedex - 1mg a day (1mg because of dbol)
Week 5-11 Arimedex- .5 mgs a day
week 1-17 vit b6 200mg a day (for acne)
PCT 5 weeks
start 14 days after last injection (pct requires 2 weeks after last test e injec.)
Plan A: Week 13-15 - Aromasin 20mg daily (reason not using arimedex is the theory of not working well with Nolvadex)
Week 13-17 - 20mg Nolvadex daily
*i read a comment in the forum on the half life of Test E being 4.5 days for Galenika (example: 800 mg test e injected, after 4.5 days it would be 400 mg theoretically). So this is why i'm considering shooting 400 mg every 4.5 days. This is of course in conjunction with the front load theory to keep the test e and blood level stable throughout the cycle.
Q1. should i drop the d bol? or increase the dosages? also would getting a pill cuter and splitting the 10 mg dbol tablets make sense for spreading throughout the day with stable blood levels?
Q2. should i take the test at diferent dosages? is it too much at once? should i shoot all 400mg at once in one muscle?
Q3. Where can i make sure that the Galenika Test E's half life is 4.5 days?
I was wondering if you guys think i should change anything or if you have any comments it would be really apreciated. Thanks
