If you plan to withdraw 1cc of oil, then inject 1cc of air into the vial. If you are planning to withdraw 2cc, then inject 2cc of air into the vial, etc., etc. But be sure to inject the air into the oil itself rather than the air contained in the vial.
For that you will need two syringes. Remove the needle from one of them and then set it aside. Then, with the other syringe, withdraw the first compound from its vial as previously instructed. Then inject that first compound into the syringe that you set aside, and then set it aside again. Then simply repeat that process with the second compound thereby combining both compounds into one syringe and then, well, rock on from there. You are at this point ready to stab yourself.
Yeah, I probably should not have attempted to explain that process via my i-phone whilst sitting in this 'spital.
If someone hasn't already taken ion this subject by the time I get back to my desktop, I'll rewrite it upon my return home. I apologize.
For test & deca I use one syringe and one needle to draw from both vials
I push 2ml air into the test, draw out 1.5ml, remove from test, then draw the syringe back as far as it will go (2.5ml syringe) insert it into the deca, inject the remaining air, then draw back 1ml deca
Job done

Go with this.
In this article series I explain how to do injections -> https://www.evolutionary.org/forums...er-injection-techniques-–-part-2-a-49351.html
I explain in depth how to prepare the syringe for injection and have detailed photos explaining everything.

Yeah, have a bit of air in the withdawing syringe, and push it into the vial to compensate for the difference in pressure once you take some of the substance out. Then push all the bubbles out of the syringe before injecting. Not a rocket science really
I have done plenty of injections, I was just curious on how people loaded one syringe with multiple esters so just have to pin once. It seems the most sanitary way would be to load syringe from one bottle then pull back plunger with enough air to push into next bottle and extract the next ester then switch out needle for a fresh smaller one

I only push air into the first vial I draw from. Then I just pull what I need from the other vial(s), change the tip, and pin as usual.
If the vials are less than half full that seems to work OK for me, but when they're full the vacuum stops the syringe plunger from drawing back easily and it tries pulling the oil back into the vial, causes the oil to squirt out the needle when I pull it out of the vial sometimes too
I'm like Masonic, I only push air into the 1st Vial.
Then once you have what you need, the Next Vial will Fill your Syringe without adding air.
I've done this with 3 Different Vials at one time.
You don't need to go crazy, it's easy, and I use a 25 Gauge to withdraw with.
Yes it's a little slower, but it eliminates having to get all that air out afterwards.
Then I just change Tips, and I'm good.......................... JP
