Some background.

• Second week of my first cycle (I had done one before but it was over 10 years ago).
• Cycle: 500mg/wk (shot every 3.5 days)
• Nutrition on point at 20% over TDEE at 50/30/20, clean food.
• Had just started HCG at 500ui/wk earlier this week.
• Arimidex and Nolvadex on hand

Blood work results (taken one week in):

DHEAS: 415 (high)
ESTRADITOL: 93 (high)
FSH: 1.67 (low)
LH: 0.31 (low)
PROGRESTONE: 2.18 (high)
PROCTALINE: 21.7 (high)

CHOLESTEROL: 240 (high)
LDL: 103
HDL: 88

BP: ~120/80

High numbers probably due to the first week of Test E without AI/HCG. Had already gained 10 pounds water weight by the time I took the bloodwork. High Cholesterol probably due to the Ketogenic diet I was on prior to the cycle, note LDL is at normal levels and HDL is high which is protective. I'm at ~15% BF

Due to high EstraditoI and itchy nips I started on Arimidex .5mg EOD earlier this week, I also started on Nolvadex 20mg ED to help control it immediately. (Though I have stopped Nova as I read it should not be taken with Arimidex)

So here is what has me worried. Today I was masturbating and couldn't get to the finish line. Off cycle I tend not to masturbate, /r/NoFap, don't watch porn. But on cycle that is just impossible. Earlier in the week I had been masturbating 2-3x a day on some days due to the the high T. So I'm there trying to get somewhere with this and you know when you just can't seem to finish so you get tired and agitated but power through cause its just out of reach, well all of a sudden I feel this flush over me and I just have to lay down right there on the carpet. I don't remember much, dunno if I passed out or not as my memory is blank for a min there. One thing I rememeber is thinking that my heartbeat is way too slow, I feel like after a session like that I should have my heart beating out of my chest, but I feel slow concentrated heartbeats instead, like. thump..........thump..........thump. After some time laying there I stand up and I'm confused feeling like there is something important i need to be thinking about. Like I had forgotten why I laid down. Had tunnel vision and found it hard to concentrate. I stumble straight to bed. My extremities were feeling cold, clear signs of low blood pressure. I take a blood pressure reading using a portable wrist device I've been using that had been giving me ~120/80 previously and I'm at 109/66. Then take it again in a few mins and its 102/60. I google about raising blood pressure on my phone, and so I go to make a coffee, put the cup on the microwave, then come back to bed to wait for it to heat up and take my BP again and I'm at 129/90, just from standing up.

Called the doctors, they came and took my BP, and listened to my heart and lungs. They told me I'm fine, that my heart sounds fine and my BP reading is normal, that even at the ranges I measured it was still within normal ranges. That it looks like it was a temporary thing. No signs of problems.

I have in the past (after my first cycle) done a full workup on my cardiovascular system and heart, even did an Echocardiogram and it all came back fine, but who knows, maybe they just didn't detect anything overtly wrong. All day today I have been feeling lethargic and weak and I'm afraid of doing any strenuous activity due to something like this happening again.

I'm taking this pretty seriously. After some googling I have surmised that I just had an Arrhythmia and I'm planning on stopping the cycle asap. Need some advice from you guys, as there is a possibility that this is just something that happens maybe due to Arimidex or Nolva sides and I may be blowing it out of proportion? Or should I cut my losses now to be safe?
