Interesting, that's definitely the lowest I think. This was the information I found but its in regards to peptides, not HGH (So 50 amino acids or less?)EU Pharmacopoeia v. 8 has 13% limit for related proteins, so 87% I guess?

The waste part of your post is written in regard to medical use... I wouldn't apply it to bodybuilding purposes
"The higher levels of >90% to >98% purity are designed for particular applications. This level is the most expensive, and it usually isn’t necessary for the applications described above. Peptides purified to the >90% to >95% level are best for quantitative bioassays, quantitative in vitro receptor-ligand interaction studies, biological activity with ligand binding studies, quantitative blocking and competitive inhibition assays, quantitative phosphorylation and proteolysis studies, electrophoresis markers and chromatography standards.
Usually, the highest level of >98% purity is reserved for in vivo studies, clinical trials, drug studies that use peptides as pharmaceuticals and structure-activity relationship studies. This level is also best for examining protein structure by nuclear magnetic resonance studies or protein crystallography (though these latter three applications also can be accomplished using the >95% purity preparation)."
Personally I don't know what a lot of these applications mean. But im assuming anything above 90% is fairly potent and considered very pure.
