Retatrutide Box (10 x 10mg)

Retatrutide Box — bulk reta, ten sealed 10mg vials

A sealed box of ten individual 10mg vials, 100mg of retatrutide in total, at $1,099.99. That is $109.99 per vial against $159.99 for a single 10mg vial bought on its own, or $11.00 per mg against $16.00.

The box is not simply a bulk discount. It is a structurally different product from the large single vials, and the difference is the expiry clock. Reconstituted retatrutide holds 28 days refrigerated. A 60mg vial puts all 60mg under one window the moment it is opened. This box gives ten separate windows, each starting only when that vial is reconstituted, with the other nine sitting sealed at full lyophilised stability.

For any study running longer than a month that is usually the deciding factor, and it is why the box is the most common bulk choice despite costing $1.17 more per milligram than the 60mg vial.

What the box contains and yields

Ten sealed vials, each holding 10mg of lyophilised retatrutide, all drawn from the same production batch so results stay comparable across the length of a study.

• 100mg total across ten independently sealed vials.
• Ten 1mg aliquots per vial, or one hundred across the box.
• Five 2mg aliquots per vial, or fifty across the box.
• Ten separate 28 day windows, one per vial, started at your choosing.

At a weekly 2mg aliquot one vial covers five weeks and the box covers roughly a year without a milligram expiring unused. No large single vial in the range can do that, and that is the whole argument for buying bulk this way rather than as one big vial.

Single-batch supply across a long study

All ten vials in a box come from one production batch and carry one batch number, matched to one certificate. For a study running months, that removes batch-to-batch variation as a confounder, which is not guaranteed when vials are reordered one at a time over a long period and may arrive from different production runs.

It also removes the reordering overhead: no repeat orders, no risk of a stock gap mid-protocol, and one certificate to file rather than several. For multi-month or multi-arm work this tends to matter more than the per-milligram saving.

Reconstituting from the box

Each vial is reconstituted individually as a standard 10mg vial. Open one at a time and leave the rest sealed. Volumes below are per vial, not for the whole box.

1.0 mL per vial at 10 mg/mL is the standard and keeps the arithmetic simple: a 1mg aliquot is 10 units on a U100 syringe. Because vials are handled one at a time there is no headroom constraint here, unlike the 30mg and 60mg vials where large fills become awkward.

One 10mL bottle of bacteriostatic water reconstitutes the entire box at the standard 1.0 mL per vial. The reconstitution calculator covers any other target concentration.

Bulk retatrutide pricing against single vials

$1,099.99 for 100mg is $11.00 per mg, second only to the 60mg vial. The same 100mg bought as ten individual 10mg vials would cost $1,599.90, so the box saves $499.91.

Only the 60mg vial beats it on headline per-mg price, at $9.83, and it does so by concentrating everything into one expiry window. Measured on material actually used rather than material bought, the box wins for any protocol slower than about 15mg a week. The 30mg vial at $12.00 per mg and 20mg at $13.50 are both more expensive per milligram than the box, so above roughly 30mg of total requirement the box is the better buy unless you specifically need one uniform solution.

Storing the box

Store the sealed vials at 2–8°C for short-term holding or −20°C for long-term, protected from light and moisture, avoiding repeated freeze-thaw. Vials can be left in the box or removed; what matters is that unopened vials stay sealed.

The 28 day refrigerated limit applies per reconstituted vial, not to the box. Opening vial one starts one clock and leaves the remaining nine untouched at full lyophilised stability. The box therefore has no group expiry to plan around, which is the main operational reason researchers choose it over a large single vial holding a similar quantity.

Planning a long protocol around the box

The box changes how a long study is scheduled, because the constraint moves from the calendar to the vial.

With a single large vial, reconstitution starts a four week countdown for the entire quantity, so the protocol has to be compressed to fit it. With the box, each vial is opened only when the preceding one is exhausted, so a study drawing 2mg a week runs five weeks per vial and roughly a year across the box, with no material discarded at any point.

Two practical notes. First, work through the vials in order and keep the batch certificate filed with the box, since all ten share one batch number. Second, a partially used box holds its value indefinitely in a way a partially used 60mg vial does not, so an interrupted or postponed study loses nothing.

Where throughput is genuinely high, the 60mg single vial at $9.83 per mg remains cheaper, and the two are worth comparing on consumption rate rather than headline price.

Specifications

Batch testing and COA

All ten vials come from one batch, tested independently by Janoshik Analytical. HPLC confirms purity at 99 percent or above and mass spectrometry confirms the measured mass against the expected molecular weight. Certificates are published in the COA library, indexed by the batch number printed on each vial. Orders before 12pm dispatch the same business day from Australian stock.

Background on the compound itself sits on the Retatrutide product page and in the retatrutide research guide, rather than being repeated on each size page.

Ordered with the box

• Bacteriostatic water — one 10mL bottle reconstitutes all ten vials at the standard 1.0 mL fill.
• Retatrutide 60mg — the cheaper per-mg alternative if throughput justifies a single window.
• Tirzepatide — the dual-agonist comparator commonly run alongside a long reta protocol.

Frequently asked questions

What is in the retatrutide box?
Ten individually sealed vials, each containing 10mg of lyophilised retatrutide, for 100mg total. All ten come from the same production batch, so there is no batch variation across the box.

How much is bulk retatrutide per vial?
$109.99 per 10mg vial, from $1,099.99 for the box of ten. A single 10mg vial bought on its own is $159.99, so the box saves $50.00 on every vial, or $499.91 across the box.

Is the box better value than the 60mg vial?
The 60mg vial is cheaper per milligram at $9.83 against $11.00, but commits all 60mg to a single 28 day window once reconstituted. The box gives ten separate windows. Below roughly 15mg a week of consumption the box wastes less material and is cheaper in practice.

How long does the box last?
Sealed vials keep indefinitely at 2 to 8 degrees Celsius short term or minus 20 degrees Celsius long term. Only the vial you reconstitute starts a 28 day clock. At a weekly 2mg aliquot one vial covers five weeks and the box covers roughly a year.

Are all ten vials from the same batch?
Yes. Boxes are supplied as a single batch, which matters for long studies because it removes batch-to-batch variation as a confounder. The batch number is printed on each vial and matches one certificate in the COA library.

How much bacteriostatic water does the box need?
1.0 mL per vial at the standard 10 mg/mL, so a single 10mL bottle reconstitutes the entire box. Each vial is opened and reconstituted individually as a normal 10mg vial.

How many aliquots does the box give in total?
One hundred 1mg aliquots, or fifty 2mg aliquots, across the ten vials. Each vial on its own gives ten 1mg or five 2mg aliquots.

Does the retatrutide box ship the same day in Australia?
Yes, on orders placed before 12pm on a business day. Boxes ship from Australian stock with tracked domestic delivery in discreet unbranded packaging.
