first i would do tren a ,and see how you like it if you dont then its out of your system alot faster.it is hit or miss with tren cough,i pinned litterly hundreds of tren a,and got the cough a hand full of times.sometimes it was really bad ,and some not that bad.yes i did toooooooo much tren,had it in every cycle.now no more tren for me ,but in all fairness i really abused the use of it.be very carefull,it gets addicting,at least for me it did.the look ,and strength are second to none
