it's a little cloudy but mainly there are a few clumps in it......
Cloudy or undissolved peptide is definitely not a good sign. This usually means that the peptide is damaged/denaturated and no longer holds the properties that would allow it to dissolve properly in its ideal solvent.
It could also possibly be a peptide that has properties not suited to the acidity of 100mM AA.
Now, I cannot vouch for your IGF or if it is in fact IGF as I do not know where it came from.
I can also not vouch for your AA as I did not make it myself, but if you followed the AA guides properly that should have turned out fine, not much you can really mess up there but some math which would not likely cause the problems you are having IMO.
Also, there have been reports of some chinese IGF-1 that has been produced in such a way that it did not dissolve in AA as it ideally should. Not sure what that IGF was buffered in that causes this reaction. Maybe someone that has some more knowledge on this issue could chime in.
I myself have never received IGF that exhibited this issue...
