HGH Fragment 176-191 10 mg Research Peptide (USA domestic)

One of our products is HGH Fragment 176-191 10 mg. It is a lyophilized research peptide that is a fragment of the C-terminal domain of human growth hormone, comprising amino acids 176-191. The 10 mg vial format is not intended for veterinary use, but is intended for use in vitro laboratory research or in humans. 

A selective lipolytic fragment (YLRIVQCRSVEGSCGF) of this sequence is examined without interference from the GH receptor binding activity of the growth hormone and IGF-1 signalling, which is characteristic of the full-length somatropin.

HGH Fragment 176-191 Product Overview

Fragment 176-191 peptide is a synthetic fragment that mimics the last 16 amino acids of the C-terminal of the recombinant human growth hormone, but with an additional tyrosine at position 177 for greater stability. 

The HGH Fragment 10mg vial is a sterile white lyophilized powder, which is sealed under vacuum and should be used for reconstitution with a suitable sterile solvent in laboratory conditions. Molecular formula C₇₈H₁₂₅N₂₃O₂₃S₂, molar mass ≈ 1817 g/mol. Batch and Lot information for each unit, along with purity information from HPLC and mass spectrometry analysis, is given on each unit.

What Is Included in the 10 mg Kit?

Researchers should look at the product card before purchasing to determine what comes in each unit. The standard HGH Fragment 176-191 10 mg kit is delivered in a single sealed HGH lyophilized vial. Often, it will not be provided automatically and needs to be confirmed in the listing.

The vial contains the active substance only – no filler compounds, carriers, or stabilizers are added beyond what is required to preserve the lyophilized form.

Compound Identity and Laboratory Research Context

The “176-191” indicates where particular amino acids are located within the molecule of human growth hormone. The fragment is the C-terminal end of the entire chain of full-length GH, which is 191 amino acids long. 

This region, the HGH 176-191 peptide, was isolated as a research tool as this area was linked with studies in animals and cultured cells, indicating that the area is associated with lipid-related signalling pathways that are thought to be independent of the receptor pathways that regulate growth. 

The scientists can study the HGH fragment 176-191 research peptide separately with the help of the research peptide. Current findings are pre-clinical and should not be extrapolated to human findings or used interchangeably with related analogues.

Quality, Batch Testing, and Documentation

Each production run of the fragment is assigned a unique lot number that stays printed on the vial label, the outer carton, and the accompanying paperwork. Before release, the batch undergoes identity confirmation by mass spectrometry and purity analysis by HPLC, with the actual figures recorded on the Certificate of Analysis (COA) for that specific lot. 

Researchers should request the COA that matches the lot code on their vial rather than relying on figures taken from an older batch. Purity values vary between runs and must be read from current batch evidence only, never assumed from previous shipments.

Storage and Laboratory Handling

The sealed, lyophilized HGH fragment 176-191 research peptide should be kept at –20 °C in a dark, dry environment, with the vial protected from direct light and temperature fluctuations. Short-term storage at +2 to +8 °C is acceptable while the vial remains unopened, provided it is used within the window stated on the label. 

Once reconstituted, the solution is far less stable and must be refrigerated. All handling steps should take place in a qualified laboratory setting by trained personnel, using sterile technique, dedicated glassware, and appropriate personal protective equipment throughout.

Ordering and USA Domestic Shipping

If you plan to buy HGH Fragment 176-191, please verify that the product is in stock, in a lot, and has a delivery date by checking the product card on the live site, as these details are updated as new product batches are processed. HGH Fragment 176-191 for sale in the USA is shipped from a domestic facility with each product packaged in a protective container to prevent light, heat, and impact exposure to the lyophilized vial. Shipping terms, tracking, and expected shipping times are provided at checkout.
