For reconstitution

What you need to reconstitute a powder.

A lyophilised powder is useless until it is mixed, and mixing it badly wastes the vial.

Bacteriostatic water, something to move it with, and something fine enough to draw the result. That is the whole kit, and reading a syringe is worth five minutes before you measure anything. The syringes and needles range has both the blunt fill and the fine one.

The short answer

Bacteriostatic water, a vial adapter or drawing-up needle, U-100 insulin syringes and alcohol swabs. We supply the diluent and the equipment, never the compound.

What we supply
Bacteriostatic water, vial adapters, drawing-up needles, insulin syringes and swabs.
What comes from your pharmacy
Whatever is in the vial you are reconstituting. We supply the diluent and the equipment, never the compound, and we do not stock peptides in any form.
The kit

How many vials a month?

Set it below and the order follows. Each line shows how long a pack lasts at that rate, so you can see what is a monthly buy and what is a once a year one.

These are indicative prices while the range is being finalised, and there is no checkout yet. Each product page takes a pre-order, which is an email address and no payment.

Quantities are a starting point, not a prescription. Your prescriber sets your dose, your route and your schedule. Where those differ from anything here, follow them.

The part that goes wrong

01
Down the wall, not onto the powder
Aim the stream at the inside of the glass and let it run down. A jet straight into the cake shears it, and what you get back is cloudy.
02
Swirl, never shake
Roll the vial between your palms until it clears. Shaking foams it, and foam is protein that is no longer doing anything useful.
03
Bacteriostatic, not sterile water
Sterile water has no preservative, so the vial is single use the moment you break it. Bacteriostatic water is preserved with benzyl alcohol and keeps for weeks refrigerated.
04
Measure in the right syringe
A 1mL insulin syringe has graduations fine enough to read a small volume. A 3mL syringe does not, and guessing between marks is how a dose goes wrong.
FAQ

Questions people actually ask.

If yours is not here, the contact form routes straight to the team that can answer it.

Do you sell peptides?
No, and we will not. Good Practice Supply supplies medical consumables. Bacteriostatic water is a diluent and the syringes are equipment. What you put in the vial is between you and your prescriber.
How much water do I add?
We cannot tell you that. It depends entirely on the compound and the dose you have been prescribed, and getting it wrong changes every subsequent measurement. Ask the person who prescribed it.
How long does a reconstituted vial last?
That depends on what is in it, not on the water. Follow the storage direction you were given with the vial.
Why an adapter instead of a needle?
Repeatedly pushing a needle through the same stopper can core out a plug of rubber into the vial. An adapter seats once and gives you a clean luer port to work through.

Three questions and we will tell you which size to pre-order.

The Gauge Finder asks what you are injecting, where, and how often. Nothing you answer is stored, and we never ask what it is for.

We are still building the range. Leave an address and we will tell you what has come in, without making a project of it.

Restock notices and new guides. Two or three emails a month at most, one click to stop, and we do not sell or share the address.
