I posted while back about not seeing results from gh. I've been on now for 8 months currently at 4 iu, 5/7. I started out with Somatropin that I got from an american pharmacy and about half way through, I switched to Jin's cause of price. I noticed that at 4 iu's with the Jin's, I would get bad sides. My arms would go numb as I would sleep and upon waking. I went back to the Somatropins about a month ago at 4 iu's and I my arms have not gone numb once. I noticed the difference immediately. I wonder why I get more sides from Jin's then Soma's?
