Hygetropin is an 191 amino acid sequence somatropin of medium quality. While it is identical to human body’s own growth hormone, the freeze dried powder may contain some bacterial residue. Users are reporting different results from batch to batch. There are some reports of painful red welts around injection spots, which may be an indication of immune response. This is a potentially dangerous side effect as it may lead to the body developing immunity to it’s naturally produced growth hormone as well.

Hygetropin came on the market in 2008 along with several other re-branded generics to fill the market vacuum which was created after Jintropin’s manufacturer license was temporarily revoked by Chinese government following a crackdown on abundant black market HGH. Before Jintropin was the most widely used growth hormone brand. It’s sudden disappearance from the market left the people scrambling to find a suitable replacement. Jintropin has since returned on the market, pushing Hygetropin aside.

Hygetropin boxes come in two sizes. Either as 10 IU vials packed in boxes of 10 vials or 8 IU vials packed in boxes of 25 vials.
