i used GP tren ace and it was some good shit man. freakin changed my physique in 6-7 weeks (diet and cardio was on point as well) and i was using 150mg EOD. i was already on test E and EQ, i thru the tren ace in there for the last 6-7 weeks.
I used them both (GP brand) along with drostolone propionate (different brand) at 350mg's EOD per compound along with HCG/A-dex and an exemestane/clompihene/tamoxifen PCT. Cycle was 10 weeks and the most productive of the 5 or 6 that I have previously ran in my estimation.
