Why are you still on test after your first cycle? Even if you weren't cruising it's still only been four weeks post cycle. Time on equals time off (off all test/gear). Your LDL, FSH, LH are due to not coming off gear. This is a mess, especially after a first cycle. Get off all gear, run proper...
A first cycle should only consist of test to evaluate how your individual body reacts to the base male hormone in larger than therapeutic doses (a cycle). Save the exotic stuff for later cycles. 400-500mg/wk 10-12 weeks only
You have nothing to worry about except out a few vials. Plenty of seizures happen without a letter. But if they wanted to get you they wouldn't just seize it and do nothing for months. Besides they don't even care about a random dude getting a few vials so don't worry
Take the loss and move on.
