Hey guys, been away for a while with personal and professional problems, but it's good to say I'm back. My last cycle of test-e 700mg/w tren 700mg/w ended Dec 10th. It was my first cycle useing tren and I loved it. Anyway, I'm looking to put together my next cycle and I was wondering how Primo compares to Mast. I love Mast and include it in almost every cycle but I also enjoy trying new things. So any of you guys who have used both please let me know how they compaire.... besides the price. Also how much you ran.
