Can someone please explain or link an explanation of the difference between 98 and 99 percent hgh?

I've done both I can't remember if one was better than the other.irwad the stickie posts on hgh in the form and searched on this site and on internet in general but can't find an explanation

Ii injured my back a couple weeks ago and plan on hgh and some peptides and work out lightly. Inremember both hgh made old military injuries much more.tolerable.

Thx
