Can't get real primo very easy, so I'd stay away from it. Most are fakes.
As a first time user, I would read a HELL of a lot and ask a lot of questions. wannabeafreak.com is a good site to post to.
For grins, here is a nice beginner's cycle that could get you upwards of 20lbs LBM if you
eat properly.
Week 1 : Test 1g (250mg Sun/Tues/Thurs/Sat), 0.5mg arimidex every other day
Week 2-8: Test 500mg (250mg Mon/Fri), 0.5mg arimidex every other day
Following up with post-
cycle therapy using clomid, arimidex, and possibly morning dbol. Do some research!
