Test e 400mg/week cycle log

[testsubject0]

I'm currently two and a half weeks into a test e 400mg per week cycle that I plan to run for 12 weeks. I may also get some test p to bridge into pct with. Planned pct is clomid and nolva, 50/50/25/25, 40/40/20/20. I have arimidex also that I've used twice already, but felt like it crashed my estrogen so I won't be using it anymore unless I see sides. My current stats are:
Age: 22
Weight: 180
Bodyfat: about 10, but you can judge for yourself
Cycle experience:
Two years ago I started test e for 5 weeks but stopped due to personal reasons, which I'm sure is for the best as I was too young and have learned and gained so much naturally since then.
Just keeping this log to track my progress and get some feedback. I work a labour job that is very active, which is taken into account for my diet, consisting of about 4k calories per day. Here is a picture from a few days ago. Will post a picture of the wheels shortly.

Here's a leg pic. I've always noticed that my left and right quads were shaped differently. My left outside seems to be shorter and bulge more, while the right one is longer down towards my knee. Is this just a genetics thing?

Today is my 6th injection of test e at 400mg. I did legs yesterday:
Squats: 135x5, 225x5, 315x5, 315x5, 225x5
Seated one leg press: 3x10
Seated one leg extension: 3x10
Lying hamstring curls: 3x10
Seated calf raises: 4x20

Strength is definitely going up by now. 315 was my one rep max not too long ago.

Yesterday was chest day, and also exactly 3 weeks since I started my cycle. I can definitely say that strength is going up by a noticable amount already. My routine was:
Flat dumbbell press: 4 sets, 10/10/8/6/4 maxing out at 100's. This is the first time I've been able to do that high since recovering from a shoulder injury I previously had
Incline dumbbell press: 3x10
Incline dumbbell flys: 3x15
Cable flys: 3x10

I usually weigh on Saturday mornings, so I will wait and see if I am putting on any weight, but there is no doubt that I feel the test working already. Some people say that test e takes up to 4-6 weeks to begin working, but I don't find this at all. Even in my last experience with test e I noticed it within 2 weeks or so
