I've cycled for years and have been on TRT for 4. I'm currently on 600 test cyp (pharmacy) and 400 primo (trusted UGL here). I have used both of these compounds multiple times. I tapered up to this dose and have been on it for 3 weeks. I had an injection 3 days ago that gave me the cough for 5 minutes (must have hit a vein on the way in) and since then I have had what feels like a knot in my stomach or like someone just punched me lightly there 15 seconds ago. There is no pain on palpitation. I also have bought of PACs my adult life - pre atrial contractions which I feel but have been ruled benign. These have increased in frequency this week. I've had the post injection cough multiple times over the last 15 years so it doesn't worry me but it just seems odd these events coincided. I thought I may have some anxiety so I have taken some low dose Xanax as I have a script but it doesn't seem to do anything. Anyone have an ideas on this? I'm pretty sure it isn't a muscle strain from the coughing but perhaps it is... perhaps it's anxiety from the cough. I'm just wondering if something internal could be going on. Usually I get bloodwork regularly but Marek seems to be having problems and I am having trouble getting a script in NY.
