At $589.99 for 60mg, this vial works out to $9.83 per mg. It is the cheapest retatrutide Omega Peptides Australia sells by a clear margin: 39 percent below the 10mg vial, 51 percent below the 5mg, and the only size in the range that breaks the $10 per mg mark.
This page carries the full retatrutide cost comparison across every vial size, because the 60mg is where that comparison ends. If you are working out what retatrutide costs in Australia and which size gives the lowest real price, the tables below cover per-vial price, cost per mg, and cost per 8mg of material drawn.
The reason the per-mg price falls this far is worth stating plainly: very few buyers can draw 60mg of reconstituted peptide inside the 28 day refrigerated window. That is the trade you are making, and it is why the Box of 10 x 10mg at $11.00 per mg often works out cheaper in practice.
What retatrutide costs in Australia by vial size
Retatrutide price scales steeply with vial size. The spread between the smallest and largest vial is $10.17 per mg, which means the same quantity of peptide can cost either $20.00 or $9.83 per milligram depending purely on how you buy it.
- 5mg at $20.00 per mg — the highest price per mg, paid for the smallest commitment.
- 10mg at $16.00 per mg — the standard single vial.
- 20mg at $13.50 per mg — the first meaningful bulk saving.
- 30mg at $12.00 per mg — the established-protocol size.
- Box of 10 x 10mg at $11.00 per mg — bulk pricing without a single expiry window.
- 60mg at $9.83 per mg — this vial, the floor of the range.
Bacteriostatic water for reconstitution is priced separately. One 10mL bottle at $29.99 covers a full 60mg vial filled to 6.0 mL, so factor roughly $30 into the cost of putting this vial into solution.
What 60mg actually yields
Sixty milligrams is the largest single vial in the range and the numbers are easy to underestimate.
- Sixty 1mg aliquots from one vial.
- Thirty 2mg aliquots, exact.
- Twenty 3mg aliquots, exact.
- Twelve 5mg aliquots, exact.
To finish the vial inside its 28 day reconstituted window you need to draw roughly 15mg per week, which is thirty 2mg aliquots across four weeks. That is a genuine throughput requirement. Below it, part of the vial expires unused and the $9.83 headline stops being the price you actually paid per usable milligram.
Reconstituting a 60mg vial
Volumes for 60mg specifically. The larger fills exceed what a standard peptide vial holds, so concentration choice is more constrained here than at any other size.
| Bacteriostatic water added | Final concentration | 1mg aliquot (U100 units) | 2mg aliquot (U100 units) |
| 2.0 mL | 30 mg/mL | 3.3 units | 6.7 units |
| 3.0 mL | 20 mg/mL | 5 units | 10 units |
| 6.0 mL | 10 mg/mL | 10 units | 20 units |
3.0 mL at 20 mg/mL is the practical default. 6.0 mL gives the more familiar 10 mg/mL but is a large volume for one vial, so check headroom first. A 5 mg/mL fill would need 12 mL, beyond both a single 10mL bottle and most vial capacities, so 5 mg/mL is not realistically available at this size.
Budget a full 10mL bottle of bacteriostatic water per vial if filling to 6.0 mL. The reconstitution calculator will confirm any target concentration before you open the vial.
Retatrutide price per mg and per 8mg drawn
The final column prices 8mg of material, a convenient unit for comparing sizes on a like-for-like basis rather than per vial.
| Vial | Price | Cost per mg | Per 8mg drawn |
| 5mg | $99.99 | $20.00 per mg | $159.98 |
| 10mg | $159.99 | $16.00 per mg | $127.99 |
| 20mg | $269.99 | $13.50 per mg | $108.00 |
| 30mg | $359.99 | $12.00 per mg | $96.00 |
| 60mg | $589.99 | $9.83 per mg | $78.67 |
| Box (10 x 10mg) | $1,099.99 | $11.00 per mg | $88.00 |
Six separate 10mg vials would cost $959.94 for the same 60mg, so this vial saves $369.95. The comparison that matters most is against the Box of 10 x 10mg: 12 percent more per milligram, but 100mg arrives as ten sealed vials each with its own 28 day window. Measured on material actually used rather than material bought, the box is cheaper for any protocol slower than about 15mg a week. The 30mg vial at $12.00 per mg is the middle option if 60mg is more than you can draw.
Storing a 60mg vial
Unopened, the lyophilised powder is as stable as any other size: 2–8°C for short-term holding, −20°C for long-term, protected from light and moisture, no repeated freeze-thaw. A sealed 60mg vial can be held indefinitely on those terms.
Reconstitution is the irreversible step at this size. All 60mg enters solution together and the 28 day refrigerated limit applies to the entire quantity. There is no partial reconstitution option for a lyophilised vial, so opening a 60mg vial should follow a firm throughput plan rather than precede one.
At $589.99 a vial, the cost of getting this wrong is the highest in the range. A 60mg vial drawn at 5mg a week uses 20mg before expiry and discards 40mg, which turns a $9.83 per mg purchase into $29.50 per usable mg, worse than buying 5mg vials one at a time.
Why retatrutide price per mg falls with vial size
The per-mg price drops from $20.00 to $9.83 across the range, and the shape of that curve is worth understanding when deciding what to order.
Most of the cost of supplying a research peptide sits in fixed per-vial steps rather than in the peptide itself: independent HPLC and mass spectrometry testing, lyophilisation, sterile filling and sealing, cold-chain handling, certification and packing. Those costs are close to identical whether the vial holds 5mg or 60mg. Spreading them across more milligrams is what produces the discount.
The practical consequence is that the saving is real but front-loaded. The jump from 5mg to 10mg saves $4.00 per mg. From 30mg to 60mg it saves $2.17. Each further step buys less, while the expiry risk attached to a single vial keeps rising. That is why the cheapest vial on paper is not automatically the cheapest material in practice, and why the box of ten sealed vials exists as a separate option at a slightly higher per-mg price.

Batch testing and COA
Every batch is independently tested by Janoshik Analytical: HPLC for purity at 99 percent or above, mass spectrometry to confirm the measured mass matches the expected molecular weight and so verify identity. Certificates are published in the COA library against the batch number on the vial. Orders before 12pm dispatch the same business day from Australian stock.

Frequently asked questions
How much does retatrutide cost in Australia?
Retatrutide ranges from $99.99 for a 5mg vial to $1,099.99 for a box of ten 10mg vials at Omega Peptides Australia. Measured per milligram the range runs from $20.00 down to $9.83, with the 60mg vial at $589.99 being the cheapest per mg.
What is the cheapest retatrutide per mg?
The 60mg vial at $589.99, which is $9.83 per mg. It is the only size under $10 per mg. The box of ten 10mg vials is next at $11.00 per mg, followed by the 30mg vial at $12.00.
What is the retatrutide price per mg at each size?
5mg is $20.00 per mg, 10mg is $16.00, 20mg is $13.50, 30mg is $12.00, the box of ten 10mg vials is $11.00 and the 60mg vial is $9.83. Bacteriostatic water is priced separately at $29.99 for a 10mL bottle.
How many doses are in a 60mg retatrutide vial?
Sixty 1mg aliquots, thirty 2mg, twenty 3mg or twelve 5mg, all exact divisions of 60mg.
How much bacteriostatic water do I add to a 60mg vial?
3.0 mL is the practical default and gives 20 mg/mL. 6.0 mL gives 10 mg/mL but is a large volume for one vial. A 5 mg/mL fill would need 12 mL, which exceeds a 10mL bottle and most vial capacities.
Is the 60mg vial or the box of ten 10mg vials better value?
The 60mg vial is cheaper per milligram, $9.83 against $11.00, but commits all 60mg to one 28 day window once reconstituted. The box gives ten separate windows. Below roughly 15mg a week of consumption the box is cheaper on material actually used.
Can one researcher use a 60mg vial within 28 days?
It requires drawing roughly 15mg per week, or thirty 2mg aliquots in four weeks, which is high throughput for a single protocol. Most single researchers cannot, which is why the multi-vial box is often the better structure.
Does the 60mg vial ship the same day in Australia?
Yes, on orders placed before 12pm on a business day, from Australian stock with tracked domestic delivery in discreet unbranded packaging.
