mixing esters

What is the correct way to mix two injectables like cyp and prop in one syringe? i tried this moring and messed my oil!

How did u mess your oil?

Pull out one vial. Eg 1ml.

Then almost like 'reset' it as if you were going to pin (take all air out). Then insert into next vial and pull required amount.

I find this way doesnt mess and its easy to measure.

Ps. Have no idea if that made any sense, but it did to me. Haha so good luck.

I haven't mixed esters but mix my vit B12 and complex injections in one syringe. I assume the concept should still stay the same.

If you doing 1ml of each, pull back the plunger to 2ml of air. In the first vial, inject 1 ml of air and then draw up 1ml of liquid. Next vial inject the remaining 1 ml of air (vial upside down to ensure air is on top in the syringe) and draw 1 ml of liquid.

I do this. Withdraw with 20g needle, inject with 23g needle

Draw 1ml air and inject this into vial No.1
Withdraw 1ml oil from vial No.1

Then take vial 2

Withdraw 1ml air again, and inject 1ml air with the vial upside down slowly into vial 2
After you injected the air, your oil from vial 1 will be very close to the end of the syringe.
Then withdraw 1ml oil slowly from vial 2

Now you should have 2ml oil in your syringe. Remember when swopping from the 20g needle, to withdraw all the oil that's in the 20g needle before placing the new 23g needle for injection.

If you did this correctly, there will no bubbles in the oil.

Take your time and do it properly.

The same method can be used for adding more oil substances.
