About HGH Fragment 176-191
What is HGH Fragment 176-191?
Overview
What is HGH Fragment 176-191?
HGH Fragment 176-191 is the C-terminal fragment of human growth hormone, covering residues 176 to 191 of the 191-residue hormone. It contains none of the regions responsible for the full hormone's receptor binding. It is supplied as a lyophilised powder in sealed vials, boxed in tens, for laboratory research use only.

These are catalogue target specifications, not batch results. The 99%+ purity figure is the specification we buy to. The authoritative figures for any particular box are the ones printed on that box’s Certificate of Analysis, which is lot-specific. What research grade actually means explains the difference. Terms such as HPLC purity and net peptide content are explained in the peptide glossary.
We make no “third-party verified” claim for a batch unless the matching report is supplied with it. Ask for the current COA for the lot in stock before you order — we will send it.

Storage & reconstitution
Handling
How should HGH Fragment 176-191 be stored and reconstituted?
Sealed vials tolerate ambient temperature in transit and keep at −20 °C beyond that. Reconstitute slowly down the vial wall, swirl rather than shake, then refrigerate at 2–8 °C and aliquot before freezing.
Why each of those matters, and what a freeze–thaw cycle actually costs: peptide handling and storage reference. How long a mixed vial keeps: reconstituted peptide shelf life.
What it is researched for
Research Context
What is HGH Fragment 176-191 researched for?
Below is a plain-English summary of what published research has investigated, and what it has found. These are descriptions of research activity and published results. They are not claims about what HGH Fragment 176-191 does, and nothing here is a statement that it is safe or effective for any purpose.
Separating fat metabolism from growth
Growth hormone does two broadly separable things: it drives growth through IGF-1, and it influences fat breakdown. This fragment was isolated to test whether the second could be obtained without the first. 1
Adipocyte studies
Most published work uses fat cell culture and rodent models, examining lipolysis and markers of fat oxidation rather than whole-body outcomes. 1
Relationship to AOD-9604
AOD-9604 is this fragment with a tyrosine added at the N-terminus. Since AOD-9604 subsequently failed to meet its Phase 2 obesity endpoint, that result is directly relevant when interpreting research on the unmodified fragment. 2

Batch COA
Verification
Does HGH Fragment 176-191 come with a COA?
Yes — every box. Each batch of HGH Fragment 176-191 is analysed by an independent third-party laboratory, and the certificate is tied to the batch number on the vial label.
Example COA. You receive the certificate matching your own batch.
Questions & answers
Questions
HGH Fragment 176-191 questions, answered
Is HGH Fragment 176-191 the same as growth hormone?
No. Human growth hormone is a 191-residue protein. This fragment is the final 16 residues of that sequence and lacks the domains that bind the growth hormone receptor. It is studied as a discrete fragment, not as a substitute for or equivalent of the intact hormone.
How much does HGH Fragment 176-191 cost?
HGH Fragment 176-191 starts at $7.53 per vial, sold in boxes of 10 vials at $75.28 per box (about £56.40). 4 strengths available: 2 mg, 5 mg, 10 mg, 15 mg. There is no minimum order.
Can I buy HGH Fragment 176-191 10mg vials in the UK?
Yes. HGH Fragment 176-191 10mg comes in boxes of 10 vials at $165.00 per box ($16.50 per vial, about £123.62 per box), sent tracked to UK addresses. There is no minimum order.
How is HGH Fragment 176-191 shipped to the UK and USA?
Tracked to the UK, USA, EU and worldwide, in plain packaging, dispatched within 1–2 working days. Country-by-country estimates are on the shipping page.
