I'd stick with the Jino's, they are the only pharmaceutical company in china, that is licensed to make the 191aa sequence HGH. Now if that's changed I don't know, but to be on the safe sided, stay with Jino.
The whole anti-body thing scares me, I know that chances are it'll never happen, but since the word "chance" is in the equation, keeps me away. I didn't have much success with HGH, LR3 works better for me.
I do have low HGH/IGF-1 levels, so some day here, a Dr is going to give me a script. Once I get my script I'll get some HGH made in the USA or Jino's. Anything that has the possibility to be a 192aa sequence, is out for me. If something did happen, I'd hate myself for trying to save a couple of bucks, now I have anti-bodies to HGH.
I am 50 Bro, so at this age, I don't want to be taking the same type of chances I was taking in my youth

I paying for some of those now.
