Pulmonary oil micro-embolism (POME)
I've had 2 or 3 that also caused flu symptoms. Chills, aches, covered up while sleeping because I felt cold. Sheets drenched in sweat when I woke up. All good.

The cough from Tren is slightly different, but similar.

That's why I inject very slowly now. The effects are pretty fast. This way I can terminate pin.

Tren cough for me has slight delay.
