HGH Fragment 176-191 5mg

Sign in for priceSold out

HGH Fragment 176-191 is the C-terminal sixteen-amino-acid region of human growth hormone. It is studied for lipolytic activity in adipocyte models, isolated from the growth-promoting and insulin-antagonising activity carried by the rest of the molecule.

About HGH Fragment 176-191 5mg

The premise behind this fragment is structural dissociation: growth hormone's effects on lipolysis and on somatic growth appear to map to different regions of the protein, and 176-191 is the region associated with the former. Because it lacks the receptor-dimerising surface of the intact hormone, it does not produce IGF-1 elevation in the models where it has been studied, which is precisely why it is used to separate the two effects experimentally. It is closely related to AOD-9604, which is this same fragment with a tyrosine added at the N-terminus for stability.

Storage and reconstitution

Store lyophilized peptide at -20°C in a dry, dark environment. Reconstitute in bacteriostatic water. Once reconstituted, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles. Lyophilized powder is stable at room temperature for shipping and short-term storage.

Shipping within Canada

Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Parcels leave British Columbia, Canada and travel entirely within the country, so nothing on this order crosses a border, clears customs or is held by CBSA. Orders over CA$200 ship free; see the shipping page for transit times by province.
