I have had issues with particles floating in multiple different peptides. Sometimes they seem to be there right away but other times ive seen them happen after a few days. I store everything in the fridge and take care to keep everything sterile so this is obviously weird. I know others have seen this. Anyone know more about it? I know the igf had been used at least once with particles in it and no ill effect occured as of yet. Not planning on it happening again though.....unless we know it is totally safe.
