Buy AOD-9604 5mg HGH fragment peptide Canada Durham Peptides
AOD-9604 is one of the more thoroughly characterized peptides in the research peptide field, with substantial published clinical research history alongside its presence as a research-use peptide. For Canadian researchers entering the lipolytic peptide research category, AOD-9604 represents a well-documented research compound — the modified HGH Fragment 176-191 analog with isolated lipolytic activity that operates independently of growth hormone receptors.
This guide covers the AOD-9604 purchase decision: what AOD-9604 is, why the structural modifications matter, what to verify before purchasing, and how Durham Peptides' Canadian-domestic supply compares to international alternatives.
The product page is at Durham Peptides AOD-9604 5mg.
For the foundational research overview, see What Is AOD-9604? A Research Overview of the HGH Fragment 176-191 Analog.
What AOD-9604 Is
AOD-9604 is a synthetic peptide consisting of the C-terminal 16 amino acids of human growth hormone (residues 176-191) plus an additional N-terminal tyrosine residue. The structural design isolates the lipolytic-relevant region of growth hormone while adding the stability-enhancing modification.
Key structural features:
17 amino acids total (the 16-amino-acid hGH fragment plus the N-terminal tyrosine)
Tyrosine modification at the N-terminus for enhanced stability and improved lipolytic activity per unit dose
Receptor-independent mechanism — does not engage growth hormone receptors
No effect on IGF-1 or glucose levels — distinguishing from full-length growth hormone or GHRH analogs
The modification creates substantial measurable differences from the unmodified HGH Fragment 176-191:
Enhanced enzymatic stability
Stronger lipolytic activity per unit dose
Substantially larger published clinical research base (AOD-9604 was the specific compound used in formal pharmaceutical clinical development)
For complete coverage of the structural and mechanistic context, see What Is AOD-9604?.
The Research Mechanism
The published research literature has investigated AOD-9604's mechanism through several distinct angles:
Lipolysis stimulation — fat breakdown in adipose tissue
Lipogenesis inhibition — reduced formation of new fat cells
Receptor-independent activity — operates without engaging GH receptors
No effect on IGF-1 or glucose homeostasis
These features distinguish AOD-9604 from full-length growth hormone or GHRH analogs like tesamorelin. AOD-9604 isolates one specific aspect of GH biology (lipolytic activity) without engaging the broader signaling pathways.
Important context: clinical development outcomes. AOD-9604 was developed by Metabolic Pharmaceuticals (Australia) through formal pharmaceutical clinical trials including Phase IIb efficacy studies. The Phase IIb trials did not meet their efficacy
endpoints, and clinical development for the original therapeutic indication was halted. AOD-9604 has not received pharmaceutical approval in any jurisdiction. Canadian researchers entering AOD-9604 research can draw from the substantial published clinical
pharmacology data while understanding that pharmaceutical efficacy was not established for the originally targeted therapeutic application.
What to Verify Before Buying AOD-9604
The standard six-criteria framework for Canadian research peptide purchases:
1. Independent third-party COA via Janoshik Analytical. AOD-9604 should have a Janoshik Certificate of Analysis publicly accessible. For Durham Peptides AOD-9604 5mg, the COA is at durhampeptides.ca/lab-results.
2. ≥99% HPLC purity. The research-grade purity standard. See Peptide Purity: Why 99% Matters.
3. Mass spectrometry identity confirmation. The molecular weight should match AOD-9604's expected value, including the N-terminal tyrosine modification mass. Important: the MS data should distinguish AOD-9604 from the unmodified HGH Fragment 176-191 — they have different molecular weights. See How to Read a Janoshik COA.
4. Solid-Phase Peptide Synthesis (SPPS) manufacturing. The peptide should be manufactured via modern synthetic chemistry with no animal-derived materials. The N-terminal tyrosine modification is incorporated as a specific synthetic step. See Vegan Peptides and Peptide Manufacturing 101.
5. Canadian-domestic supply. Eliminates customs uncertainty and currency conversion costs. See Peptides for Sale in Canada.
6. Research-use-only framing. Reputable suppliers maintain consistent research-use language. See 5 Things to Look for in a Canadian Peptide Supplier.
Reconstitution and Storage
AOD-9604 follows the standard research peptide reconstitution and storage framework:
Reconstitution. Use bacteriostatic water. Reconstitution math depends on the desired concentration. For step-by-step process and math, see How to Reconstitute Peptides and Peptide Reconstitution Calculator Guide, or use the Durham Peptides peptide calculator.
Storage. Lyophilized vials refrigerated (2-8°C) for moderate-term, frozen (-20°C) for long-term. Reconstituted vials refrigerated only, used within ~28 days. See Peptide Storage & Shelf Life: How to Store BPC-157, Tirzepatide, and Other Research Peptides.

Frequently Asked Questions
What is AOD-9604? A synthetic peptide consisting of the C-terminal 16 amino acids of human growth hormone (residues 176-191) plus an added N-terminal tyrosine residue. See What Is AOD-9604?.
Does Durham Peptides sell AOD-9604? Yes. AOD-9604 5mg is now available with full Janoshik third-party testing and Canadian-domestic shipping.
Is AOD-9604 the same as HGH Fragment 176-191? Not exactly. HGH Fragment 176-191 is the natural unmodified C-terminal sequence. AOD-9604 has the same core sequence with an added N-terminal tyrosine residue. AOD-9604 has the more substantial published clinical research base.
Does AOD-9604 contain growth hormone? No. AOD-9604 is a fragment of growth hormone — specifically the C-terminal lipolytic region. It doesn't contain the full GH protein and doesn't engage GH receptors.
Is AOD-9604 FDA-approved? No. Phase IIb clinical trials failed to meet efficacy endpoints, and clinical development was discontinued. AOD-9604 has not received pharmaceutical approval in any jurisdiction.
Is AOD-9604 approved by Health Canada? No. AOD-9604 is not approved by Health Canada for human or veterinary therapeutic use. It is sold under research-use-only framing.
Is AOD-9604 tested? Yes. Durham Peptides AOD-9604 5mg is independently tested by Janoshik Analytical with verifiable COA available at durhampeptides.ca/lab-results.
Is AOD-9604 vegan? Yes. Manufactured via Solid-Phase Peptide Synthesis with synthetic amino acids. See Vegan Peptides.
What's AOD-9604's purity standard? ≥99% HPLC purity with mass spectrometry identity confirmation. The Janoshik COA shows both.
How fast does AOD-9604 ship in Canada? Same-day Ontario shipping with typical 2-5 business day delivery across Canada. Canadian-domestic shipping eliminates customs uncertainty.
What's AOD-9604's shelf life? Standard research peptide framework — approximately 12-18 months refrigerated, 24+ months frozen for the lyophilized form. Approximately 28 days under refrigeration after reconstitution. See Peptide Storage & Shelf Life.
How is AOD-9604 different from tesamorelin? AOD-9604 is a downstream fragment of GH with isolated lipolytic activity that doesn't engage GH receptors. Tesamorelin is a GHRH analog that works upstream of GH release by prompting the pituitary's natural release of endogenous GH. Different mechanisms in different parts of the GH biology pathway.
Final Thoughts
AOD-9604 is one of the better-characterized research peptides in terms of clinical research history, with substantial published pharmaceutical development data alongside continued research peptide use. The structural design — isolating the lipolytic region of growth hormone with the N-terminal tyrosine modification for stability and potency — represents a thoughtful approach to studying isolated GH biological activity.
For Canadian researchers, AOD-9604 is now available through Durham Peptides as AOD-9604 5mg — manufactured via Solid-Phase Peptide Synthesis, third-party tested by Janoshik Analytical, and sold with the same research-use-only framework that applies to the entire catalog.
