yeah I took it with a tren cycle too and the pumps were so bad during leg presses I had to wait like 3 minutes in between sets and walk laps around the gym lol...vascularity was insane as well
First time I used n2amp me and a bro from work popped 8 and a scoop of n2kts before we got off of work. God that was an intense workout, vascularity was great and we just killed it at the gym. Needless to say we both couldn't sleep for shit that night lol. Now I find for me 4-6 caps and a scoop of n2kts is the perfect combo
