Re:need some advice
I quite like P-Mag as a novice bulk cycle.
Generally few sides and I found quite rapid qualiy weight gain when I ran it. Only snag is really needing 2 bottles as I would suggest running it 75mg for 4 weeks which is caps a day from a 60 cap bottle = 20 days per bottle :-( But it kicks in as fast as anything I have ever used - around 10 days which is what you want on a first cycle as you I suspect you will be excited and waiting for things to happen!
Also though like Vibora - Epi is a decent shout, though for me provides more noticeable gains in strength then mass. This is best run upto 6 weeks as it is slower to kick in.
