iu is internationale eenheid...ze vonden die mg(mcg) waarschijnlijk te onduidelijk waardoor ze overgegaan zijn op iu's...en dan is ongeveer 1mg gelijk aan 3iu (Dit geldt alleen voor hgh)...dus de verhouding iu/mg voor slin is weer anders...
Stomme is dat die amerikaanse hgh vaak nog wel met mg werken waardoor het weer neit veel duidelijker wordt...
". It is noted that for the U.S.-American growth hormone compounds, the substance con tent is not given in 1-U. (International Units) but in mg (milligrams). Since I mg corresponds to exactly 2.7 I.U. the 5 mg solution of the compound Humatrope by Lilly contains exactly 13.5 I.U. of Somatropin. The 10 mg solution of the Protropin compound by Genentech therefore contains 27 I.U. of Somatropin. In American powerlifting and bodybuilding circles Humatrope is usually preferred over Protropin. The reason is that Humatrope is synthesized from a chain of 191 amino acids and thus is identical to the amino acid sequence of the human growth hormone. Protropin, on the other hand, consists of 192 amino acids, one amino acid too many. This might be the explanation for why more antibodies are developed with Protropin than with Humatrope. Growth hormones are on the doping list but they are not yet detectable during doping tests.
