Top three vendors

Card one is our pick. Every card is labeled.
10 mg is the size most vendors sell, so these cards compare that size only. Of the 7 vendors selling it, we sort by published testing first, then price per mg.

Card one came out on top. It is also a partner, so we earn a commission there. One of the other two cards is a store we partner with, and we earn a commission from it. The other is the next store in the sort, and we earn nothing from it.

Three things price per mg does not tell you

A cheap milligram is only cheap if the vial holds it.
Fill weight

The label is a claim, not a measurement

Every per mg number here divides the price by the milligrams printed on the vial. Testing labs regularly find vials that weigh less than the label says.

Landed cost

Shipping and card fees are not in these numbers

Shipping is often flat, so it hurts small orders most. Several vendors add a card fee and discount for crypto. Two offers a dollar apart can swap places at checkout.

Vial size

Bigger vials look cheaper and go off just as fast

A bigger vial costs less per mg and expires on the same schedule. Once mixed, most people work to about 28 days in the fridge, so the saving only counts if you finish it.

05

How wide the price gap really is

Same compound, same buyers, very different tickets.
4.5x
Cheap end to dear end

Ignoring the few freak listings at each extreme, the dear end of the Mazdutide market costs 4.5 times what the cheap end does, per milligram.

$8.33
Middle of the pack

Half these listings charge more than this per mg and half charge less. It moves with sales, which is why every row carries a date.

16
Vendors carrying it

Enough coverage to show a real range. Anything under three vendors stays off the hub.

Same peptide, 16 vendorsNothing on the glass tells you which seller will show you a lab report you can open, or what a milligram actually costs. That is what the table above is for.
06

What you are actually buying

Regulatory status changes what a price means.
Mazdutide vial, mock product photograph
Regulatory status

Investigational

Approved by China's regulator in 2025 for weight management and later for type 2 diabetes. It is NOT FDA-approved. The FDA has issued a warning letter to a US peptide vendor selling it, since 'research use only' labeling does not make it legal for human use.

Full Mazdutide record →
What that changes

Nobody stands behind a research vial

There is no pharmacist behind it, no dispensing record, and nobody on the hook for what is inside. The lab report is the whole quality system, which is why it sits next to the price here.

Research use only is a claim the seller has to keep making. A vendor that adds dosing instructions, health claims, or personal-use wording has stepped outside the framework it relies on, and that says something about the seller.

What customs and carriers do varies by state and by shipper. This describes how these products are sold and is not legal advice.

07

Before the vial arrives

What actually shows up, and the vial math that decides which size is the better buy.
Mazdutide, mock product photograph
Storage

Frozen dry, refrigerated wet

Freeze-dried powder keeps for a long time in the freezer and for months in the fridge. Once liquid goes in, most people work to about 28 days in the fridge, away from light.

Mazdutide, mock product photograph
Mixing

Bacteriostatic water and insulin syringes are extra

What arrives is powder in a sealed vial. Water goes down the inside wall rather than onto the powder, and the vial is swirled instead of shaken. Neither the water nor the syringes are in the prices above.

Vial economics

The bigger vial is only cheaper if you finish it

A larger Mazdutide vial costs less per mg and expires on the same schedule once mixed. The saving is real only when the vial runs out inside that window.

Nothing on this page tells you what to take. Full walkthroughs live in the guides.

08

How this table is built

What decides the order of the rows, and who gets to be in them.
Ordering

Cheapest per mg first, and nothing else

Rows sort on one number. There is no combined score and no weighting, so no vendor can be pushed up the table by a rating you cannot check.

Inclusion

Doing badly does not get a vendor removed

Vendors that publish nothing stay in the table, marked. Taking them out would make the market look tidier than we found it.

Prices

Every price has a date on it

Prices are read off public catalog pages and saved with the date. If a check runs late the row says so instead of showing an old price as current.

Money

Sorting never reads who pays us

Commissioned links are marked on the row and listed on the disclosure page. They never move a listing up or down the table.

How these prices are collected

Prices on this site are read from vendor websites on the dates shown. A starting tag means the vendor publishes only a from price for that product. A wall means the vendor hides prices behind a login, and we publish that fact rather than hide the gap.

We report prices and never rate or score an offer. There is no value grade, no ranking of vendors by our opinion. A row carries its size, its price, its price per milligram, and any plain fact about the listing worth knowing.

When a vendor's site disappears, its rows stay in the tables as a dated record, drop out of every count, price range and ranking, and lose their links. Ninety days after a vendor's site disappears, its rows leave these tables and remain in our records.

Some vendors pay this site a commission when you buy through our links. Every one of those links is marked, and every vendor with that arrangement is labeled on the vendor page. Commissions never change the prices we show, the order of any table, a vendor's badge, or anything in the audit record. The data is collected the same way for every vendor, paid or not.

We accept no payment for coverage, placement, or ratings. Warning letters come from fda.gov. If a paying vendor earns a bad mark, the mark stays.

Questions about buying mazdutide

Cost, sizes, and how this table works.
How much does Mazdutide cost?+

The most-sold size, 10 mg, runs $52.00 to $249.99 a vial across 5 vendors, with a median of $110.00. Across 15 vendors it typically runs $5.50 to $25.00 per milligram, with the cheapest sticker price at $52.00. Prices exclude shipping, card fees, and bacteriostatic water.

Why is the same vial so much cheaper at one vendor?+

Vial size, sale cycles, payment method discounts, and how much testing evidence a seller publishes all move the number. A cheap milligram is only cheap if the vial holds what the label claims, which no price column can tell you.

Do you make money if I buy?+

Sorting never reads whether a vendor pays us. Any commissioned link is marked on the row and listed on the disclosure page, and it never changes where a listing lands in the table.

Is mazdutide legal to buy?+

Approved by China's regulator in 2025 for weight management and later for type 2 diabetes. It is NOT FDA-approved. The FDA has issued a warning letter to a US peptide vendor selling it, since 'research use only' labeling does not make it legal for human use.

How current are these prices?+

Every price is read off a public catalog page and stored with its date; this compound was last read Oct 11, 2026. Nothing is overwritten, so a stale row says so rather than pretending to be current.
