To that end although commonly used as PO drug excipients, I'm baffled how an otherwise uncategorized "starch" would end up as the primary, if not the only compound, in a vial of that is supposed to contain GH.
Bc of it's cohesive properties starch is an ideal excipient for many drug tablets or capsules.
However unless a parenteral drug manufacture likes the idea of a less soluble compact wad, rather than a lyophilized product at the bottom of a vial, only small amounts of starch would be permissible.
So in this instance I'm inclined to believe there was a deliberate attempt to deceive consumers ------ AND for that reason the results of a single assay may will represent the entire lot ------- a deliberate attempt to DEFRAUD consumers.
Compare this to say a GT lab that lacks the QC, oversight, or checks and balances of a Pharma facility. Sure their QC needs improving but it's impossible to know if they are deliberately shorting the consumer.
