If you're looking into a product labeled 100IU HGH, the headline potency is only one piece of the puzzle. Other useful things to check are: the exact product identity; declared strength and formulation; the batch or lot reference; a Certificate of Analysis (CoA), if available; analytical testing data; any manufacturer or lab paperwork; storage conditions; and the stated research-use classification. A batch-specific CoA helps link analytical results to a particular lot. When a CoA exists, its details should match the exact material being evaluated.
