On 1st cycle,few questions after researching,AI,PCT

[WMSuperSport]

I'll keep it as simple as I can. Thanks for reading, & I aplogize if I say something wrong or dumb.
First cycle ever, Test E250 & EQ300, 1cc twice a week -3 weeks in now, planning on 10wks?
30yo, 6'2", 213lbs, worked out for around 7 years, and am decently knowledgable on diet and lifting.

I took some advice from a work friend who hooked up me with the test & EQ. I'm really enjoying the effects, but I didn't research until after starting my cycle unfortunately. My head feels like exploding sometimes, from the hours of reading the info here each day. Since I'm new I'm learning the lingo, acronyms, & things with other common or shortened names, etc. There also seems to be conflicting opinions, views, & scientific info that is way complicated and over my head.

*The past couple of weeks of I'm taking triazole as an AI, but have read enough to want to switch to Liquidex(Arimidex) from AR-R. I'm thinking about starting .25mg Arimidex daily ASAP. Is this correct?
Also, I've had slightly fat tits my whole life because I grew up overweight. When I lean out it goes away. Should I get Letrozole in case i think i start to get gyno at some point?

*On PCT, I plan on using 100mg liquid Clomid & 20mg liquid Tamox daily, with .25mg Arimidex daily, for about a month??
The reason I chose these is from research and availability from AR-R.
Do I need to taper down the test & EQ the last couple of weeks? I have heard this before, but not actually read it lately...

*Is this AR-R the place to go?

*Is it recommended by many to use HCG? I have never heard of it until reading here, and I have no idea if I can even get it...

My only hookup is the type that may not be reliable in supply all the time. I'm seriously considering cycling many times, since I'm having very good results all around. I hope I can ask if anyone could point me in the right direction on this one?

I think this is enough questions for now, but if anyone has anything else to add, or think I need to include into my cycle, please let me know and thanks alot for any info!
