About HGH 191AA (Somatropin)
Human growth hormone is a single-chain protein of 191 amino acids with two disulfide bonds and a mass of about 22 kDa. “191AA” in the listing name signals that the material matches this full natural sequence, as opposed to older methionyl-GH or other variants.
HGH 191AA (Somatropin) is also the active ingredient of licensed pharmaceutical products in some markets. The material listed here is supplied for laboratory research only; it is not a pharmaceutical product and must not be used as one.
