How to store and handle your vials.

Every order leaves us cold. Vials are packed at 2–8°C, wrapped in insulated packaging with cold packs, and delivered the same day across Bali. Longer routes are packed for the journey, so the cold holds until the parcel is in your hands.

Every vial carries a batch number, and every batch has a certificate of analysis on file — ask and we'll send it.

1. 01Check the packaging is still cold when it reaches you.
2. 02Check the batch number on the vial matches the paperwork in the parcel.
3. 03Move the vials into the fridge straight away.
4. 04Don't leave the parcel sitting in a hot car or on a doorstep.

Lyophilized (freeze-dried) vials, before mixing, are the most stable form. The fridge at 2–8°C is the normal choice. Keep them away from light and leave them in their box while they sit.

For long-term storage, a freezer is possible for some compounds. Avoid repeated warming and cooling — take a vial out once, when you intend to use it, rather than moving it in and out.

Once bacteriostatic water has been added, the rules tighten:

• Always in the fridge at 2–8°C. Never in the freezer once mixed.
• Keep the vial upright.
• Keep it away from the fridge door, where the temperature swings every time it opens.
• Write the date you mixed it on the label.

Store it at room temperature or in the fridge, sealed, away from light. Replace it if the seal is broken or the water looks cloudy.

• Let a cold vial sit a few minutes before handling it.
• Add water slowly down the side of the glass, rather than straight onto the powder.
• Swirl gently. Never shake.
• Wipe the rubber stopper with an alcohol swab before each use.
• Use a fresh needle every time.
• Never share a vial between people.

Heat and humidity are the main challenge here. A fridge that opens often, or sits in a warm room, works harder than it should — a small dedicated fridge, opened rarely, is the reliable option, with a thermometer kept inside it so you know the real temperature rather than guessing.

During a power cut, keep the fridge closed. A full fridge holds its temperature for hours with the door shut; opening it resets that clock.

Moving vials between islands, or across town on a scooter, use an insulated bag with a cold pack — the same principle our own packaging relies on.

The exact window depends on the compound and the batch. The certificate of analysis for each batch is the reference — ask and we'll send it.

Stop and check with us if you notice any of these:

• Powder that has clumped or changed colour
• A cloudy solution, or particles in it, after mixing
• A cracked vial
• A stopper that has lifted or is damaged
• A parcel that arrived warm

Don't use it. Message us with the batch number and we'll take it from there.
