I'm just looking into it at mo, as I said I'm on 1st cycle (sus250 2xs week) and I made sure that was pharma grade (1mm amps) my buddy has just started it he's on 2ius a day 5 on 2 off and he's getting pins and needles sensation in wrist (he's on 2nd week) and he's running sus and dec along side... he's 16.5 stone but needs to lose a lot of body fat where as im 12.5 with low bf.
