Retatrutide Starter Kit: 10mg Vial, Bacteriostatic Water, Syringes and Swabs
The Retatrutide Starter Kit is the way most Australian researchers make their first order of Retatrutide. One sealed 10mg vial of lyophilised, Janoshik-tested Retatrutide arrives with everything needed to bring it into solution and draw measured aliquots: a 10mL vial of bacteriostatic water, five 1mL U-100 insulin syringes and two alcohol swabs. Nothing else has to be sourced separately.
Held in Sydney stock and dispatched the same business day on orders confirmed before 12pm AEST, tracked to every Australian address. Searched as reta starter kit, retatrutide kit australia, retatrutide starter pack and retatrutide bundle.

What is in the kit
1 x Retatrutide 10mg
Lyophilised powder in a sealed sterile vial, ≥99% HPLC purity, batch COA from Janoshik Analytical. $159.99 on its own.
1 x Bacteriostatic water 10mL
Sterile water with 0.9% benzyl alcohol, the preservative that keeps a reconstituted vial usable across repeated draws for 28 days. $29.99 on its own.
5 x 1mL insulin syringes
Sterile, individually sealed, fixed-needle U-100 syringes graduated in units, for measuring the water in and the aliquots out. $15.99 on their own.
2 x alcohol swabs
Individually sealed, for wiping both vial septa before every puncture. Not sold separately.
Why the pieces are supplied together
Retatrutide is supplied as a freeze-dried cake and does nothing until it is dissolved. Bacteriostatic water is the recommended diluent because it adds no salts or buffers and its preservative stops bacterial growth across the multiple draws a research vial receives. The syringes measure both directions: the water going in, which sets the concentration, and the aliquots coming out, which set the amount. The swabs keep the septa clean. A 10mL water vial is more than a single 10mg vial needs, so there is diluent left over for a second vial or another compound.
The kit is priced at $189.99 against $205.97 for the three priced components bought separately, so the saving is $15.98 with the swabs included on top. The main value is one verified order that is ready to reconstitute on arrival.
About the compound
Triple receptor agonist
Retatrutide (LY3437943) activates the GLP-1, GIP and glucagon receptors in one molecule. It is the most searched research peptide in Australia and reports the largest weight reductions of any compound in its class.
Published trial record
Phase 2 (NEJM 2023): up to 24.2% at 48 weeks. TRIUMPH-1 Phase 3 (May 2026): 28.3% at 80 weeks, 30.3% at 104 weeks. Full trial summary on the Retatrutide page.
Six-day half-life
A C20 fatty diacid binds serum albumin, so every published protocol uses once-weekly administration and steady state takes four to five weeks.
Why 10mg to start
Ten 1mg or five 2mg aliquots, enough for a first protocol inside the 28-day window a reconstituted vial stays stable. Larger sizes from 20mg to 60mg sit on the main Retatrutide page.

Reconstitution with the kit
Two millilitres gives 5mg/mL, so 1mg is 20 units
Swab both septa. Draw 2mL of bacteriostatic water into a syringe and run it slowly down the inside wall of the Retatrutide vial rather than onto the powder. Swirl until clear, never shake, label the vial with the date and concentration, refrigerate at 2 to 8°C and use within 28 days.
| Water added | Concentration | 1mg on a U-100 syringe | Vial yields |
| 1mL | 10mg/mL | 10 units | Ten 1mg draws |
| 2mL | 5mg/mL | 20 units | Ten 1mg draws |
| 3mL | 3.33mg/mL | 30 units | Ten 1mg draws |
The reconstitution calculator covers any other target. The five syringes cover the water draw plus four aliquots; the 10 pack adds more.
Quality and COA verification
The Retatrutide in every kit is from a batch tested by Janoshik Analytical: HPLC purity, mass-spec identity, heavy metals and endotoxin. The batch number on the vial matches its certificate. The water is sterile-filled under a tamper-evident cap; syringes and swabs are individually sealed.

Retatrutide Starter Kit FAQ
What is in the Retatrutide Starter Kit?
One 10mg vial of lyophilised, COA-verified Retatrutide, one 10mL vial of bacteriostatic water, five 1mL sterile insulin syringes and two alcohol swabs. Everything needed to reconstitute the vial and draw measured aliquots arrives in one order.
What is Retatrutide?
A 39-amino-acid synthetic peptide developed by Eli Lilly (LY3437943) that activates the GLP-1, GIP and glucagon receptors together. It is studied in obesity, type 2 diabetes, fatty liver and cardiovascular models and reports the largest weight reductions of any compound in its class.
Do I need bacteriostatic water and syringes?
Yes. Retatrutide is a dry lyophilised powder and has to be dissolved before it can be used in any protocol. Bacteriostatic water is the recommended diluent because its preservative keeps the vial usable across repeated draws, and unit-graduated 1mL syringes measure the water in and the aliquots out.
How much do I save with the kit?
$15.98 against buying the vial ($159.99), 10mL water ($29.99) and a 5 pack of syringes ($15.99) separately, with the two swabs included on top since they are not sold on their own.
Can I buy the items separately?
Yes. Retatrutide is listed on its own in six sizes, bacteriostatic water in 3mL and 10mL, and syringes in 5 and 10 packs. The swabs are only available in kits.
How do you reconstitute Retatrutide with the kit?
Swab both septa, draw 2mL of bacteriostatic water and add it slowly down the inside wall of the Retatrutide vial. Swirl until clear, never shake, refrigerate at 2 to 8°C and use within 28 days. At 2mL, 1mg is 20 units on the syringe.
How should the kit be stored?
The unopened vial at -20°C long term or 2 to 8°C short term, away from light. Once reconstituted, refrigerated and used within 28 days. Water, syringes and swabs at room temperature with seals intact.
Can I buy a Retatrutide kit at Chemist Warehouse?
No. Retatrutide is not a registered medicine anywhere and is not stocked by any Australian pharmacy. Research kits like this one are the only format it is available in.
Where can I buy the Retatrutide Starter Kit in Australia?
From this page. Pure Peptides Australia holds the kit in Sydney and dispatches same business day on orders confirmed before 12pm AEST, tracked Australia-wide. Melbourne, Brisbane, Perth and Adelaide metro addresses typically receive Express Post in one to three business days.
What does the Retatrutide Starter Kit cost?
$189.99, which is about $16.00 per mg of peptide plus the supplies. The Premium Kit is $329.99 for two vials. No surcharge on PayID, Osko or bank transfer.
Starter Kit vs Premium Kit: which one?
Starter Kit for a first order or a single protocol inside 28 days. Premium Kit if the research runs longer than one vial covers; the second vial stays sealed until needed and the per-vial cost is lower.
Is Retatrutide legal in Australia?
Pure Peptides Australia supplies it strictly for lawful in-vitro laboratory research. It is not approved by the TGA for human or veterinary use and is not sold as a medicine, supplement or therapeutic good. Purchasers are responsible for ensuring their use complies with applicable laws.
