The peptide industry, unfortunately, is flooded with counterfeit, under-dosed, or severely contaminated products synthesized in unregulated environments
If visible particles or a cloudy layer remain after 20 minutes, the peptide has likely aggregated due to temperature damage during shipping or improper lyophilisation
Observed heterogeneity likely reflects differences in comparator drugs (DPP-4 inhibitors vs
