AOD-9604 For Sale: Price, Vial Size, and How to Verify It

AOD-9604 for sale in 2026 means one thing: a 5mg research vial, currently $55, and no regulator standing behind it. Your only leverage is documentation.

AOD-9604 price and specs

Ascension pricing as of July 2026. These are promotional prices and will move.

Current listing: Ascension Peptides. They publish batch-specific third-party certificates from two named labs rather than one reused document, and describe their sourcing plainly without dressing a research chemical up as a medicine. Naming the lab and the lot is a harder trust signal to fake than a purity percentage typed onto a page.

Pricing sanity check

Peptide synthesis has a real cost floor. Building a 16-amino-acid sequence, purifying it, lyophilizing, filling and testing all cost money, and no vendor absorbs that out of goodwill. Across the current market, 5mg vials run roughly $40 to $75 depending on how much testing the seller actually pays for. Smaller 2mg vials sit near $25, and 8-10mg vials around $60 to $85.

Compare per milligram, since larger vials almost always cost less per milligram. A 5mg vial listed at $12 has not found a clever supply chain. Something has been cut, and the two cheapest things to cut are the analytical testing and the powder in the vial. Premium pricing proves nothing either: an expensive vial with no lot-specific COA is just a costlier gamble.

What you are actually buying

AOD-9604 is a 16-amino-acid synthetic peptide reproducing the C-terminal tail of human growth hormone, residues 177-191, with a tyrosine added at the front for stability. It carries CAS number 221231-10-3 and a molecular weight of roughly 1,815 daltons. Metabolic Pharmaceuticals developed it at Monash University in Australia as a candidate obesity drug, on the theory that growth hormone's fat-mobilizing portion could be isolated from the parts that raise blood glucose and IGF-1.

Early animal work reported increased fat breakdown in obese rodent models without the rise in blood glucose associated with full-length growth hormone. The receptor pathway has never been settled, and vendor explanations are more confident than the literature. The human program is where the story changes: the obesity trials did not produce weight loss meaningfully better than placebo, and the drug never reached market. Vendor pages quote the encouraging early work and stop there.

What "AOD-9604 for sale" legally means

Every listing sits in the research-chemical channel. There is no prescription route, no compounding pharmacy route, and no dietary-supplement route. The FDA has explicitly declined to allow AOD-9604 as a bulk substance for compounding, closing the one door people assume exists. The consequences are the entire reason to read a COA:

• No regulator inspects the facility, checks fill weight, or verifies sterility.
• The seller decides unilaterally what testing to disclose and what to omit.
• There is no recall mechanism. If a batch is bad, nobody tells you.
• The "research use" label keeps the transaction legal for the seller, not for you.

Treat the paperwork as the product.

How to read an AOD-9604 COA

A certificate of analysis describes one specific production lot. Most buyers glance at the purity percentage and move on, but that percentage is the least informative part of the document. Work through it in this order.

1. Lot number. Compare the batch number on the COA character-for-character to the number printed on your vial. If the vendor cannot produce a COA for your specific lot before you order, treat the document as marketing.

2. Analysis date. A lot-specific report should be recent, ideally within six months of the batch date. An undated COA, or one dated years back, describes material you are not buying.

3. HPLC purity. High-performance liquid chromatography separates the target peptide from truncated sequences, deletion products, and residual synthesis reagents. For a short 16-mer, insist on 98% or higher; under 95% is a manufacturing failure, not a discount. If the chromatogram is published, a single dominant peak on a flat baseline tells you more than a typed number.

4. Mass spectrometry identity. The check most buyers skip, and the one that catches substitution. Mass spec should confirm an observed mass close to 1,815 Da. Peptide powders all look identical, so a cheaper fragment can be sold as AOD-9604 indefinitely if nobody runs an identity test. A purity figure with no identity data only tells you the vial contains 99% of something.

5. Peptide content. A vial can be 99% pure by HPLC and still be underfilled, because purity and quantity are different measurements. Look for peptide content against net weight, plus endotoxin data via LAL testing on injectable-format product.

Third-party testing, or it does not count

An in-house COA is a vendor grading its own homework. Independent third-party testing means a lab with no stake in the result ran the sample and will confirm the report number if you contact them. Labs that recur here include Janoshik Analytical, MZ Biolabs, Kovera, and Peptide Test. A lab name on a PDF is not verification. Verification is emailing the lab with the report number, and fabricated COAs are common enough to make that worth ten minutes.

What physically arrives

Research AOD-9604 ships as a lyophilized (freeze-dried) powder in a sealed glass vial, usually a small white cake or thin film at the bottom. It is not pre-mixed, and the quantity looks alarmingly small the first time you see it. That is normal for milligram amounts. Sealed vials are typically stored at -20°C long-term; peptides in solution are far less stable and are kept refrigerated.

Be wary of any seller bundling "dosing instructions for personal use" with the vial. That contradicts the research-use-only basis the market operates on, and a vendor willing to ignore that line is telling you something about their other standards.

Red flags to walk away from

• No COA, or one generic COA reused across every product and batch.
• A COA whose lot number does not match the vial, or a vial with no lot number.
• Purity claimed with no mass spectrometry identity data.
• A lab with no record of the report number when you contact them.
• Prices dramatically below the market with no stated reason.
• Marketing promising fat loss, citing "clinically proven" results, or giving human dosing protocols.
• Evasion when asked about synthesis source, testing methodology, or endotoxin data.

Any single item is reason enough to stop. They rarely appear alone.

Legal and safety reality

AOD-9604 is not an approved drug in the US, EU, UK or Australia, and is not an established supplement ingredient. It appears on the World Anti-Doping Agency Prohibited List as a growth hormone fragment, so any athlete subject to testing carries a real sanction risk regardless of how the product was labeled. Human safety data is thin, limited to the clinical program that ended without approval: short-term tolerability looked unremarkable, and long-term data does not exist.

Quick pre-purchase checklist

1. Can the vendor send a lot-specific COA before you pay, and does its number match the vial?
2. Is HPLC purity 98% or higher, with a visible chromatogram?
3. Is there mass spec identity confirmation near 1,815 Da?
4. Is the lab independent, and does it confirm the report exists?
5. Does the price sit inside the normal per-milligram range?
6. Does the vendor avoid medical claims and dosing instructions?

Six yeses is the bar. Anything less, keep looking.

FAQ

How much does AOD-9604 cost?

A 5mg vial is the standard unit. Ascension lists it at $55.00, reduced from $74.99, which is $11.00/mg as of July 2026. Across four vendors checked in July 2026, 5mg vials ran $41 to $49, and an 8mg listing sat near $60. Compare per milligram, and treat anything far below these figures as a warning rather than a deal.

Is AOD-9604 legal to buy?

AOD-9604 can be bought legally in most jurisdictions as a research chemical labeled for laboratory use only. It is not legal to sell as a medicine or supplement, it is not FDA-approved for any indication, and the FDA has declined to permit it as a bulk substance for compounding. Buying it for personal use sits outside the regulated medical system.

How do I know AOD-9604 is real?

Insist on a batch-specific certificate of analysis showing HPLC purity of 98% or higher and mass spectrometry identity confirmation near 1,815 daltons, then verify the report number with the independent lab named on it. Without the identity test, AOD-9604 cannot be distinguished from a cheaper peptide of similar appearance.

Do I need a prescription for AOD-9604?

No, because no prescription exists to be written. AOD-9604 is not an approved drug, so no clinician can legitimately prescribe it and no pharmacy can dispense it. That reflects an absence of regulatory oversight, not an easier path.

Does AOD-9604 have proven fat-loss results in humans?

The animal work was encouraging, but the human obesity program did not show significant weight loss over placebo and development stopped. Any vendor calling AOD-9604 clinically proven for fat loss is overstating the evidence.

If you have decided to buy

The decision reduces to whether a vendor will show you real documents for your specific lot. Ascension Peptides publishes per-batch third-party COAs from MZ Biolabs and Kovera and ships from US domestic stock at $55 for 5mg, the standard we would hold any supplier to. Whoever you choose, ask for the lot-specific certificate before you pay, and match it to the vial when it lands.
