Where to buy AOD9604 Peptide: sizes, price per mg and how to verify the lot

What "aod9604 peptide" names, and what it does not

AOD9604 is a copy of residues 177 to 191 of human growth hormone with a tyrosine added at the N-terminus: Tyr-Leu-Arg-Ile-Val-Gln-Cys-Arg-Ser-Val-Glu-Gly-Ser-Cys-Gly-Phe, sixteen residues, with the two cysteines joined by a disulfide bridge. Formula C78H123N23O23S2, average mass 1,815.1 Da. Metabolic Pharmaceuticals in Australia developed it in the early 2000s, and the papers cited at the foot of this page are that programme's metabolic studies. Listings write AOD-9604, AOD 9604, aod9604 peptide and hGH fragment 177-191; one molecule, though the last name properly belongs to the fragment without the extra tyrosine, 163 Da lighter.

Supplier copy routinely credits AOD9604 with the pharmacology of whole growth hormone, which is a 191-residue protein of about 22 kDa; the fragment is sixteen residues and 1.8 kDa, and the primary research does not support treating the two as interchangeable. This page makes no claim either way. What it does say is that a certificate for AOD9604 can be read precisely, because the disulfide gives the molecule a chemistry that shows up in the numbers.

The bridge is the thing to understand. When the two cysteines are joined, the molecule is 2 Da lighter than when they are free, so an oxidised (correctly folded) lot reads 1,813.9 Da monoisotopic and a reduced lot 1,815.9. A lot where the bridge formed between two molecules instead of within one is a dimer at twice the mass. A laboratory that reports the mass to the dalton and shows a single main peak has answered the question that matters most for this peptide.

The reference point for identity is public. PubChem lists AOD-9604 as CID 71300630 with molecular formula C78H123N23O23S2, an average molecular weight of 1815.1 Da and a monoisotopic mass of 1813.86 Da. Those are the numbers a mass spectrometer is checked against, and the number a certificate must print beside the observed mass.

In plain terms: A man-made peptide matching the tail end of human growth hormone. No approved drug product. Supplier copy routinely credits it with the pharmacology of whole growth hormone, which the primary research does not support.

AOD9604 for sale: sizes and price per mg

LabFirst lists AOD9604 in 2 sizes (5mg, 10mg) from $44 to $75, priced per vial with the per-mg figure beside it so sizes can be compared without arithmetic. Per mg, the 5mg vial is the cheapest today at $8.80 and the 5mg the dearest at $8.80, which is the reverse of the usual shape; the table below is the arithmetic, and the per-mg column, not the vial price, is the one to compare.

The volume tiers are per size, not per basket: ten vials of one size take 10% off that line and twenty take 15%, and mixed sizes do not combine. Shipping is a flat $15 on orders under $200 and free from $200, within the United States only, with same-day dispatch on orders placed before 12 PM Pacific on a business day. The cost per mg tool runs the same comparison across any two listings, ours or anyone else's.

Sixteen residues with a disulfide to form and check is a moderately priced synthesis, dearer than a short linear peptide because the folding step and its verification add work. The per-milligram figure falls from the 5 mg to the 10 mg vial for the usual reason, the vial, the fill and the laboratory run being fixed costs spread over more mass. A laboratory qualifying a lot buys the 5 mg vial once and reads its certificate for the bridged mass before buying larger.

Price is where the des-tyrosine and reduced-form traps show. The fifteen-residue fragment without the extra tyrosine is cheaper and 163 Da lighter; an unfolded lot that skipped the oxidation step is cheaper still and 2 Da heavier. Both appear under the AOD9604 name at prices that look like discounts, and the certificate's observed mass is the only defence. The only discounts on this page are the volume tiers, per size and unchanged month to month, and the lot on the vial is whatever the certificate index says on the day.

The certificate a AOD9604 lot must carry

Three tests answer three different questions, and a certificate of analysis for AOD9604 is only complete when it carries all three for the exact lot on the vial. Identity is settled by mass spectrometry, and the number to look for on a AOD9604 certificate is 1813.86 Da monoisotopic (or 1815.1 Da average, if the laboratory reports the deconvoluted average mass). The observed mass should sit within the instrument's stated tolerance of that figure, and the certificate should print both the theoretical and the observed value, not just a tick.

Purity is a separate question, answered by HPLC: how much of what came off the column was the compound. The figure is only interpretable with its method beside it (column, gradient, detection wavelength) and a date, which is what ICH Q2(R2) means when it asks that an analytical procedure be shown fit for its purpose. A percentage with no method and no date is a number somebody typed, and a certificate that carries every test but for a different lot number than the vial is the most common failure of all and the easiest to catch. Net content is the third test and the one most often missing: the milligrams of AOD9604 actually in the vial, measured, against the size printed on the label.

Identity is the observed mass against 1,813.860 Da monoisotopic for the bridged peptide (1,815.1 Da average), seen in electrospray as the doubly charged ion near m/z 907.9 and the triply charged near 605.6. Three readings tell three stories: 1,813.9 is the bridged molecule; 1,815.9 is the reduced form with both thiols free, which is a different chemical state and less stable; about 3,628 Da is a disulfide-linked dimer. A mass 163 Da low is the fragment without its N-terminal tyrosine, hGH(177-191) proper, which is cheaper to make and sometimes shipped under the AOD9604 name.

Purity by HPLC should show the chromatogram with its conditions, because the reduced form and the dimer run near the main peak and are the impurities that matter here; a bare percentage cannot show they were resolved. Net content is the third line: AOD9604 is supplied as an acetate or a trifluoroacetate salt, and on a 5 mg vial the gap between milligrams of powder and milligrams of peptide can be a fifth. Quantitative HPLC against a standard or amino acid analysis tells you which the label counts, and the counter-ion belongs beside that figure.

Where to buy AOD9604: five checks before you order from anyone

Every seller of aod9604 peptide says "third-party tested". The phrase costs nothing. These five checks take about four minutes per listing and separate a tested lot from a tested-sounding one.

1. The lot on the vial is the lot on the certificate. Read the printed lot number, then open the certificate and match it. A certificate for "AOD9604" with no lot, or a lot that does not match, describes some other vial.
2. The laboratory is named and has its own lookup. The report should come from a laboratory the seller does not own, with a search code you can enter on the laboratory's own site. LabFirst lots are tested by Freedom Diagnostics and looked up by accession number; anything that can only be verified on the seller's own page has not been verified.
3. The theoretical mass is printed, and it is the right one. For AOD9604 that is 1813.86 Da monoisotopic; a certificate that prints a different figure has either measured a different molecule or copied a template.
4. Purity has a method and a date. An HPLC percentage should name the method and the run date. A figure that reads "99%+" with neither, or one date reused across every product a seller lists, is decoration.
5. Net content is stated in milligrams. The label size is a claim; the certificate's net content is the measurement. If the certificate has no net content line, the purity figure describes the powder, not the vial, and the price per mg you calculated is fiction.

How listings for AOD9604 specifically mislead:

• "hGH fragment 176-191" or "177-191" sold as AOD9604 with no mass. AOD9604 carries an extra N-terminal tyrosine; the bare fragment is 163 Da lighter, cheaper, and a different compound.
• A certificate reading 1,815.9 Da and calling it conforming. That is the reduced, unbridged form, 2 Da heavier than the folded molecule; a careful laboratory reports which state it saw.
• Copy that describes AOD9604 as growth hormone. The fragment is sixteen residues of a 191-residue protein; nothing about the whole protein's behaviour transfers by name.
• "Pharmaceutical grade AOD9604". There is no USP monograph and no approved product; the FDA placed it in Category 2 of its 503A list in September 2023, so no pharmacy may compound it.

How to verify a LabFirst AOD9604 lot

The AOD9604 sizes in stock today carry lot LF-2608-04. Lot LF-2608-04 is at Freedom Diagnostics on accession FD-2026-05716 for identity, purity and net content. Until the report is attached the product page says "pending verification" against that lot and makes no purity claim; the price stands and the report goes live the day it arrives, on the page, at /coa/, and inside the receipt and packing slip for every order of that lot.

Verification runs through the laboratory, not through us. Open the certificate index, find the lot, and use the accession number on the Freedom Diagnostics lookup page; the report you see there is the laboratory's copy, not ours. Each lot also carries a Finnrick verify link, and every receipt and packing slip states that a customer may submit a sealed vial to Finnrick's free testing programme with the order as proof of purchase, so the brand's public record is built from vials we did not choose.

The product page reads the live stock feed on load (stock, lot and certificate state for every size), so what you see when you order is what ships. The lot is printed on the label and encoded in the QR patch on its right-hand side; scanning it opens that lot's record.

Storage and shipping for AOD9604

The disulfide is the storage story. Lyophilised and sealed at 2 to 8 C out of light, AOD9604 keeps its bridge and its mass for the shelf period on the certificate. In solution, disulfides scramble: a bridge can open, re-form between two molecules and produce dimers, and the rate rises with pH, temperature and time, so a prepared solution is dated, kept cold, kept out of light and used inside the laboratory's own stability record rather than any figure on a label. The dry cake's other enemy is water drawn from humid air once the vial is opened; open a vial once, for its purpose, and never re-seal one for storage, because a cake that has absorbed moisture no longer weighs what the label says.

Orders ship within the United States, flat $15 under $200 and free above it, same day when placed before 12 PM Pacific on a business day, and the shipping page states the cutoff, the carriers and what is and is not promised.

The record a laboratory keeps on arrival is what makes the certificate usable later, and it is short:

• the lot number as printed on the vial, and the certificate's accession or search code beside it;
• the date received and the condition of the seal;
• the storage location and temperature it went into;
• the number of vials, and later the date each one was opened and by whom.

A AOD9604 vial with that record behind it can be traced from the bench to the laboratory report in one step; without it, the certificate is a document about a vial that can no longer be identified.

Regulatory status, and what this page is not

No approved medicine contains AOD9604 and no USP or Ph. Eur. monograph defines an acceptable lot; the Australian development programme did not result in a product. In September 2023 the FDA placed AOD-9604 in Category 2 of its interim list of bulk drug substances nominated for compounding under section 503A, the category for substances it has identified as raising significant safety risks, which bars licensed pharmacies from compounding with it. That listing concerns pharmacies, not laboratory material, and is quoted because "pharmacy grade" and "compounded quality" appear in listings for a substance no pharmacy may currently compound.

FOR LABORATORY AND IN-VITRO RESEARCH USE ONLY. NOT FOR HUMAN OR ANIMAL CONSUMPTION. LabFirst sells AOD9604 to laboratories and researchers as material for in-vitro work, gives no guidance on use, and ships only against that understanding. Nothing on this page or on the product page describes preparing or administering anything.

What is AOD9604 studied for?

Published research on AOD9604 investigates the areas below — which is a different question from what AOD9604 will do for anyone, a claim about a living system that nothing on this site is sold for.

What it is. A man-made peptide matching the tail end of human growth hormone.

What the research looks at. It appears in a limited set of animal and early human studies about that piece of the hormone.

How it is thought to work. A piece of the hormone rather than the whole thing, and it does not carry growth hormone’s full range of effects. The published accounts of how it works are not settled.

What is not established. No approved drug product. Supplier copy routinely credits it with the pharmacology of whole growth hormone, which the primary research does not support.

The full record, including the certificate for the lot in stock, is on the AOD9604 product page.
