changing hgh in the middle

[doitnow3]

Hey Guys,

Is there any problem with switching from serostim to the chinese stuf and back and forth......also, I was told the chinese version must be refrigerated even though it is not mixed.....does it not come in crystal form to be reconstituted?...why?.......also, does anyone who has used both have any preference of the 2?
Thanks in advance.

I prefer Jintropin over Serostim. I have used both. Jin does need to be in the fridge at all times and it does need to be reconstituted.

There should be no difference in the GH, as all GH in the 191 chain amino sequence is the same.
