HGH Frag 176-191 5 mg

HGH Frag 176-191 5 mg — the lipolytic fragment of the growth hormone molecule
Not a whole hormone but a deliberately isolated tail: amino acids 176 to 191 of the human growth hormone chain. Researchers use it precisely because it separates one signalling region from the rest of the molecule.

What is HGH Frag 176-191?

HGH Fragment 176-191 is a synthetic peptide corresponding to the C-terminal region of human growth hormone. The scientific interest lies in dissociation: the full 191-amino-acid hormone carries multiple, sometimes competing, biological activities, and this fragment was characterised in order to study the lipid-metabolism-associated portion in isolation from the growth-promoting and IGF-1-mediating regions. That makes it a precision tool rather than a blunt one — a way for researchers to ask narrow questions about a single functional domain.

Research interest

• Adipose tissue metabolism — studied in research contexts examining lipolytic signalling within fat cells.
• Structure-function mapping — a classic example of fragment-based research used to assign specific activities to specific regions of a large hormone.
• Receptor independence — of interest to researchers investigating signalling that appears distinct from the classical GH receptor pathway.
• Comparative peptide work — frequently benchmarked against full-length somatropin in studies isolating metabolic from growth-related effects.
• Energy substrate research — referenced in preclinical literature concerned with fat versus carbohydrate utilisation.

Because the value of this fragment is its specificity, sequence fidelity is everything. A truncated or incorrectly folded preparation would confound exactly the domain-Level questions the peptide exists to answer — hence the batch-level identity testing applied to every Rogue lot.

Specifications

• Content: 5 mg of active substance per vial
• Form: Lyophilised powder (vial)
• Purity: Pharmaceutical-grade, batch-tested and lot-traceable
• Presentation: Sealed, tamper-evident single vial
• Storage: -20 °C sealed; 2-8 °C short-term

Handling & storage

Lyophilised material is best held at -20 °C in the sealed, unopened vial. Refrigeration at 2-8 °C is acceptable for short-term handling. Protect from light, humidity and repeated freeze-thaw exposure. The lyophilised fragment is stable when kept sealed, dry and frozen. Bring vials to room temperature before opening. After laboratory reconstitution with a suitable sterile diluent, refrigerate, shield from light and avoid repeated freeze-thaw cycling, which degrades short Peptides rapidly.

Why source from Rogue

• Verified purity — every batch is identity- and purity-tested, with documentation traceable back to the production lot.
• European supply chain — sealed vials, authenticated manufacturing, never grey-market repackaging.
• Cold-aware logistics — protective packaging and fast, tracked dispatch across the EU.
• Discreet handling — plain outer packaging and full order confidentiality, from checkout to doorstep.
