Quick answer: AOD-9604 vs growth hormone comes down to size and scope. Growth hormone is a large protein, while AOD-9604 is a short peptide based on one small region of it, positions 176 to 191. Researchers study AOD-9604 mainly for fat metabolism pathways, not for the broad range of activity the full molecule is associated with.
What is AOD-9604?
AOD-9604 is a synthetic peptide derived from the 176-191 fragment of growth hormone (HGH). You may also see it written as AOD9604, AOD 9604 or HGH Fragment 176-191. A peptide is a short chain of amino acids, the building blocks of proteins.
The 176-191 region sits at the end of the growth hormone chain. Researchers have looked at it on its own because it has been linked to lipid (fat) metabolism in laboratory work. That is the idea behind this compound: take one region and study it apart from the rest of the molecule.
How does AOD-9604 differ from full growth hormone?
The table compares the two on the points that matter when you are choosing a research material.
| Point | Full growth hormone | AOD-9604 |
|---|---|---|
| What it is | A large protein of 191 amino acids | A short synthetic peptide based on positions 176-191 |
| Scope of activity | Broad, with growth hormone receptor signaling and IGF-1 involvement | Described as acting on lipid metabolism pathways |
| Main research focus | Many areas of physiology | Lipolysis, lipogenesis and adipose tissue regulation |
| Link to IGF-1 | Closely tied to IGF-1 signaling | Described as not significantly affecting growth hormone levels or IGF-1 signaling |
| Form in our catalog | Not offered | 10mg lyophilized powder |
The IGF-1 point comes from how the compound is described in the research literature and on our product page. It is a design aim of the fragment approach, and we present it as that.
What has published research examined?
Researchers have used AOD-9604 in metabolic and body composition research models. The themes are consistent:
- Lipolysis: the breakdown of stored fat. Laboratory studies have examined whether the fragment stimulates it in fat tissue.
- Lipogenesis: the formation of fat. The same work has looked at whether the fragment inhibits it.
- Energy utilization: how fat tissue and metabolic pathways respond under controlled conditions.
These are descriptions of what researchers examined. They are not statements about what the compound does for anyone.
How strong is the evidence?
It is early and limited. Most of what is written about AOD-9604 describes laboratory research in cells and in preclinical models. Findings from those settings do not settle how a compound behaves more broadly, and the proposed mechanism has not been fully resolved. Anyone reading a claim that goes beyond that should ask which study it came from and what kind of study it was.
What is in the AOD-9604 10mg vial?
Our AOD-9604 | 10mg is a research-grade peptide supplied as a lyophilized (freeze-dried) powder. The label strength is 10mg per vial. Our peptides are synthesized at a WHO/GMP and ISO 9001 certified laboratory in California.
For more on why peptides ship as powder, see Lyophilization Explained. For why the same compound appears in different strengths, see Why the Same Peptide Comes in 2mg, 5mg, and 10mg Vials.
How is AOD-9604 tested?
Three checks matter for a peptide like this:
- Identity by mass. Mass spectrometry confirms the molecule has the weight expected for AOD-9604 and not a different sequence.
- Purity by HPLC. This separates the main peptide from related impurities and reports the main peak as a share of the total.
- Content per vial. This shows how much peptide is actually present, which can differ from the powder weight.
Short synthetic peptides can carry shortened or incomplete chains left from synthesis. A high purity figure alone will not tell you whether the main peak is the right molecule, so read the mass result as well. The Certificate of Analysis (COA) for this product should show all three checks and match the lot on your vial.
Our guide to reading a peptide Certificate of Analysis explains each line.
How should AOD-9604 be stored?
The product page lists refrigeration. Keep the vial sealed and follow the storage line on your lot paperwork. Heat, light and moisture are the usual threats to peptide stability.
Frequently asked questions
Does AOD-9604 contain growth hormone?
No. It is a synthetic peptide based on a 16-position region of the growth hormone sequence, not the full 191-amino-acid protein.
Is HGH Fragment 176-191 the same as AOD-9604?
They are closely related and often used as names for the same research topic. Confirm the exact sequence on the product page and COA for any lot you buy.
Why does the vial say 10mg if there may be some moisture or salts in it?
The label states the intended peptide content. A content result on the COA is how you check that against the vial.
Can AOD-9604 be used outside a laboratory?
No. It is sold for laboratory research use only and is not for human or animal use.
What should I check first on an AOD-9604 COA?
Start with the lot number, then the mass result for identity, then the HPLC purity and content figures.
Every lot we sell has a Certificate of Analysis you can read before you order. Questions before you buy? Our team is in Chandler, Arizona: (888) 745-1505 or our contact page.
