HGH Fragment 176-191 corresponds to the exact C-terminal 16 amino acids of human growth hormone. Unlike AOD9604 (which has an additional N-terminal tyrosine), this is the unmodified native fragment. Research examines its lipolytic signaling properties isolated from the full-length hGH molecule.

Compound Overview
HGH Fragment 176-191 represents the exact C-terminal 16 amino acids of human growth hormone. In contrast to AOD9604, which includes an additional N-terminal tyrosine, this compound is the unmodified native fragment. Laboratory research evaluates its isolated lipolytic signaling properties apart from the full-length hGH molecule.
Research Background & Published Literature
Monash University studies identified this region as the minimal active fragment associated with the fat metabolism effects of hGH. Published work has examined the isolated fragment in relation to lipogenesis and lipolysis without somatotropic activity.
Researchers reviewing the literature around this compound can use the peer-reviewed resources below for additional context on mechanism of action, signaling pathways, and controlled laboratory research applications:

Storage, Handling & Stability Guidelines
Use the applicable lot/source record for storage of unopened material. Any diluent selection, preparation, temperature, aliquoting, or post-reconstitution hold conditions must be established by a qualified laboratory under a validated SOP; this page does not establish a stability window.
- Keep ambient-temperature exposure brief during handling to help preserve compound integrity.
- Reseal vials promptly after each withdrawal to reduce moisture exposure.
- Use appropriate personal protective equipment and follow institutional chemical safety protocols at all times.
- For traceability, label all aliquots with compound name, concentration, reconstitution date, and operator initials.
Quality Assurance & Lab Verification
A finalized public Certificate of Analysis is available for this catalog item. Review the public COA for the applicable lot. Lot-specific identifiers, assay values, and methods are maintained in that record and are not repeated in this product dossier.
Shipping
Orders ship within the United States via USPS; international orders are not accepted. Laboratories should follow their validated SOP together with any handling fields published for the represented product or lot; no universal prepared-solution condition is inferred here.

Research context.
Studies at Monash University characterized this region as the minimal active fragment responsible for hGH's fat metabolism effects. Published research examines how this isolated fragment affects lipogenesis and lipolysis without somatotropic activity.
Verification standard.
Certificate information is lot-specific. A finalized public record shows only the methods, fields, and results present for that named lot. A pending certificate state exposes no assay values and must not be interpreted as analytical verification. Review Nexus lab verification.
