Recombinant human Growth Hormone (rHGH / Somatropin, 191 amino acids) was assessed by Janoshik Analytical using the HPLC-SE (size exclusion) method specific to rHGH vial assessment. This identifies the correct 22 kDa isoform and detects degradation products and concentration accuracy. The lab assessment confirms molecular integrity, correct isoform presence, and declared IU concentration — critical quality markers that distinguish pharmaceutical-grade GH from counterfeit or degraded products.
