It’s be interesting to recon with 3ml sterile and then extract into a larger sterile vial and inject another 3ml custom 1.8% to 2% BA sterile soln in a larger vial (giving a 0.9%-1% final BA percentage). Just as an experiment to see if it’s really a concentration-specific issue or a SSA/source production issue. Taking pictures at each step…
Chinese UGLs have used the "Sterile water not BAC" shit for years when any peptide reconstitution issue comes up. Heard it multiple times from QSC and others.
That ain't it.
Higher concentration promotes aggregation (along with other factors), and 40-42iu is pushing the limit in a 3ml vial. At that concentration, without any surfactant excipients (used by pharma for high concentration rHGH), if anything is a little off, slightly damaged monomers (from heat, light, oxygen, agitation while reconstituting), aggregation is pretty likely.
Reports on lobster of similar issues from a couple of customers. Seems to happen more in the Summer months, which makes me think it may be exposure to very high heat in transit.
