This is a reply from MAMTA about the Chinese Generic GH I borrowed from another board. I didnt post the lab assay becuase its very small and written in Chinese:
the following lab report was done by an independent lab which cost a bomb.
extensive tests were done for the following.. its purtiy its amino acid seq and some other tests for its quality.
the results clearly show that it is 191 amino acid seq. and purity much more than 95 percent..
