Retatrutide 20mg Australia
Single 20mg vial, the mid-size format for longer or two-arm protocols
The Retatrutide 20mg vial doubles the material of the 10mg for 15% less per milligram. One sealed vial of 20mg lyophilised Retatrutide, Janoshik tested at 99%+ purity, held in Sydney and dispatched the same business day on orders confirmed before 12pm AEST. This is the size for researchers who know the compound already and want to get a whole protocol out of one open vial.

Why the 20mg vial
Twenty 1mg aliquots or ten 2mg aliquots fit inside the 8 to 12 week stability window without opening a second vial.
Split into two 10mg reconstitutions on different dates so both arms draw from the same COA-matched lot.
$14.50/mg against $17.00/mg, a saving of $50 on the same 20mg.
If a reconstituted vial is lost or degrades, 20mg is a smaller write-off than 30mg or 60mg.
Reconstitution table for a 20mg vial
| Bac water added | Concentration | 1mg on a U-100 syringe |
| 2mL | 10mg/mL | 10 units |
| 3mL | 6.67mg/mL | 15 units |
| 4mL | 5mg/mL | 20 units |
Note the vial capacity. A standard 3mL vial will not take 4mL comfortably, so 20mg is usually reconstituted at 2mL (10mg/mL) and drawn in smaller unit counts, or split across two reconstitutions. For reference, the TRIUMPH-1 Phase 3 programme (n=2,339, 80 weeks) reported on 4mg, 9mg and 12mg weekly arms. That describes the sponsor's controlled trial of a pharmaceutical-grade product, not instructions for research material.
How to get Retatrutide 20mg in Australia
Add to cart, check out with card, PayID, Osko or bank transfer, and the parcel leaves Sydney the same business day if payment clears before 12pm AEST.

Retatrutide 20mg FAQ
How much is Retatrutide 20mg in Australia?
$289.99 per vial, $14.50 per mg. Two 10mg vials would cost $339.98 for the same material.
Where can I buy Retatrutide 20mg in Australia?
From this page. Stock is held in Sydney and dispatched same business day before 12pm AEST with Australia Post tracking. No international shipping.
Should I get one 20mg or two 10mg vials?
One 20mg is $50 cheaper. Two 10mg vials make sense if the protocol runs longer than 12 weeks, because each vial is only reconstituted when needed and the second one stays sealed at -20°C.
How much bacteriostatic water for a 20mg vial?
2mL is standard, giving 10mg/mL (1mg = 10 units). 3mL gives 6.67mg/mL. The vial does not hold more than about 3mL.
Can I reconstitute half the vial?
No. Lyophilised powder cannot be split dry. Reconstitute the whole 20mg, then draw and freeze aliquots if a protocol needs the material spread beyond 12 weeks.
Is the 20mg vial the same batch as the 10mg?
Not always. Each vial size is filled from its own lot and has its own COA in the COA library. Check the batch number on the vial label.
How is the 20mg vial shipped?
In a padded, plain box with the vial secured. Lyophilised Retatrutide is stable at room temperature for the length of domestic transit; refrigerate on arrival.
What is Retatrutide?
A synthetic triple agonist peptide that activates the GLP-1, GIP and glucagon receptors together. The 30mg page carries the full compound overview and trial summary.
