The 10 mg vial: the titration starting point
This is the smallest retatrutide vial we stock, and it exists for the front end of a protocol — the phase where amounts are low, the schedule is still being established, and committing to a 30 mg reservoir makes no sense. At 5 mg/mL reconstituted it also gives the most forgiving syringe volumes of any vial in the range, which matters when the amounts are small.
For what retatrutide is, the receptor pharmacology, and how it compares to the other incretin peptides, see the retatrutide hub. This page covers this vial.

Reconstituting a 10 mg vial
Adding 2 mL of bacteriostatic water gives:
10 mg ÷ 2 mL = 5 mg/mL
| Amount | Volume | U-100 syringe |
|---|
| 2 mg | 0.40 mL | 40 units |
| 3 mg | 0.60 mL | 60 units |
| 4 mg | 0.80 mL | 80 units |
These are the roundest numbers in the retatrutide range — every common amount lands on a clean syringe mark, with no fractional units to squint at. That is the practical argument for starting here rather than dividing a larger vial into small amounts. Run your own figures through the dosage calculator.
How many doses is a 10 mg vial?
At 2 mL of bacteriostatic water, a 10 mg vial gives 5 aliquots at 2 mg, or roughly 3 at 3 mg. On a weekly research cadence that is about a month of material at the low end — which lines up with the ~30-day refrigerated shelf life of the reconstituted solution, so very little is wasted.
That alignment is the reason this vial suits the titration phase: bigger vials tend to expire before they empty at these amounts.
Storage and handling
Refrigerate the lyophilised vial at 2–8 °C; it ships dry because the powder tolerates ambient transit. Once reconstituted, refrigerate and use within about 30 days. Bacteriostatic water (0.9% benzyl alcohol) permits multiple draws; sterile water is single-use. Don't freeze the reconstituted solution, keep it out of light, and discard anything cloudy or containing particulate. See the storage guide and reconstitution walkthrough.
Regulatory status: investigational everywhere
Retatrutide is an investigational compound. It has no marketing approval from Health Canada, the FDA, or any other regulator, anywhere in the world — it remains in clinical development and has never been authorised for human use.
There is no approved version of retatrutide to compare this vial against, and no prescription route to it. It is supplied for laboratory research use only, shipped within Canada only, and it is not a medicine.
Retatrutide and anti-doping
WADA's S0 (non-approved substances) category covers any pharmacological substance with no current approval from any governmental health authority for human therapeutic use, explicitly including drugs under clinical development. Retatrutide has no such approval anywhere.
By that definition retatrutide sits in S0, which is prohibited at all times — in and out of competition, with no washout window that makes it compliant. Tested athletes should treat it as off-limits and confirm against the WADA Prohibited List directly.
Moving up from 10 mg
If a protocol titrates past what this vial supports economically, the range continues: the 20 mg vial is the bridge, the 30 mg vial is the reservoir, and the 15 mg reloadable pen trades vial-and-syringe work for dial-a-dose delivery.
Frequently asked questions
How many doses are in a 10 mg retatrutide vial?
Reconstituted with 2 mL of bacteriostatic water, a 10 mg vial gives about 5 aliquots at 2 mg or 3 at 3 mg. The reconstituted solution keeps roughly 30 days refrigerated, which at a weekly cadence is well matched to the vial's size.
How do you reconstitute a 10 mg retatrutide vial?
Add bacteriostatic water slowly down the vial wall and let the cake dissolve without shaking. With 2 mL, a 10 mg vial gives 5 mg/mL — so 2 mg is 0.4 mL, or 40 units on a U-100 insulin syringe.
Which retatrutide vial size should I start with?
The 10 mg vial is the smallest we stock and gives the roundest syringe volumes at low amounts, which is why it suits early titration. Larger vials are more economical per milligram but tend to reach their 30-day reconstituted shelf life before they empty at small amounts.
Is retatrutide approved anywhere?
No. Retatrutide is investigational and holds no marketing approval from Health Canada, the FDA, or any other regulator. It remains in clinical development and is supplied here for laboratory research use only.
Is retatrutide banned in sport?
Yes, in effect. WADA's S0 category covers substances with no approval from any health authority for human use, including drugs in clinical development — which describes retatrutide. S0 substances are prohibited at all times, in and out of competition.
Do you ship retatrutide across Canada?
Yes — Canada-wide, priced in CAD, with a flat $25 shipping rate. We do not ship to the United States or internationally.
