You'll frickin love GH!! I have used: serostim, nutropin,humatrope,saizen in the past and you will definately know if ur shits good pretty quickly...the pumps are frickin insane(almost too crazy)...I have gotten great results using 3-4iu's/day 4 days on, 3 days off...this was a very common way to use when I used it(1998-2002ish)...when I took nutropin(from Walgreens), it was 110% legit and when I went over 4iu's the pump was so bad it was hard to finish even half my workout and my frickin hands would always "fall asleep"..I did use insulin on and off but stopped the day I felt like I was literally going to die(prolly was)...I would definately use GH again the same way I did before bc it worked well so why change it...thin skin, roadmap vascularity, crazy pumps, the abilty to stay lean and feel full(muscles) ALL the time...just a few awesome side effects I experienced!!! Good luck brother, you look frickin great already cant wait to see the "after GH" pics!!!
