I am currently on week 5 of my cycle, i'm running 500mg's of test e every week and also running 400mg of masteron as well.... I just got two 10ml bottles of test p and was wondering if i should add it to what i'm running right now? I would love to hear peoples opinions on this and get some feedback. Can you tell me what it will do for me if added now? If I need more, I can buy some more..... that's not a problem. I know the half life of prop is like 2-3 days so is that saying if I injected let's just say right now would i notice a difference in the gym tonight? tomorrow? off the first prop inject? Anyway thanks guys!
