The compound can push heart rate higher and cause palpitations in some users, which then gets read as panic symptoms.
First month went smoothly. Then in the most recent couple of weeks I had two sudden episodes a few days after dosing that felt like panic attacks: pounding heart, wave of anxiety, and that intense sense something was wrong. The second one was bad enough I ended up at the VA getting Ativan and fluids. I had only experienced anything similar twice before and both times there were obvious stressors, which weren't present here. Electrolytes and blood sugar were already handled and didn't help. Labs looked normal and even the staff seemed surprised. For people further along: did panic-type feelings ever appear later rather than early, did they hit one to three days after the shot, and did anything besides dropping the dose or just waiting make a difference? Not seeking advice, just comparing notes.
