How HGH is supplied
HGH is supplied as a lyophilised powder supplied in international units (iu), commonly as 10iu vials in 100iu kits, or as a pre-filled pen. Reported half-life: Short in circulation, typically two to three hours; downstream IGF-1 elevation persists considerably longer. Storage: Refrigerated at 2-8 C both before and after reconstitution. Never frozen. Growth hormone is a folded protein and loses activity if frozen or shaken vigorously.

Why presentation changes the comparison
Cost per milligram is calculated from the strength printed on the listing. Where a listing states no strength the column is left blank rather than estimated. Growth hormone is stated in international units, so a comparison against anything priced per milligram needs converting first.
