First time I've had it and for me it was attributable to not warming my gear and my thigh up with a hairdryer! I was in a rush so did it a quick 0.5ml shot and boom tren cough for 15 minutes. Never experienced anything like it. However I was under the impression it subsides after this time? It's been a day and I've still got this nasty niggle of oil at the back of my throat. Everytime I take a deep inhale I instantly feel it and cough. Is this normal? I don't see any other tren cough cases ongoing like this after a 30 min spell.
