Firstly I am sorry if this is not in the proper location, and I understand I should not have taken Deca and test for my first cycle
however I request the opinion of those who can help

I am on week four of Test blend 400 and deca 300
Gains have been great with relatively no side effects
however, this week I have discovered an accelerated heart rate at strange times and also inability to achieve a full breath of air. I am now fatigued in the gym and light headed. YES I know I should go to the hospital and I will be going now. However Im wondering if any of you might have any insight or experience with this?
I was told water retention can cause laboured breathing?
Any advise or experience would be very much appreciated
Thank you.
