What causes syringe plunger to push back once injected into vial

[carbon adams]

Normally with test c 200 I push .5ml of air into vial and syringe plunger stay down and I can retract and draw .5ml

What do it mean if you inject your desire dose of air into vial , even if only .1ml of air and after you do that , the syringe plunger doesn’t stay down, but insteads pushes back and syringe fill with air again

With all due respect and I too used to wonder why....... now I say worry about your food intake and gym.

I say with utmost respect and I too used too worry until I realized this simple method KISS

Hey bro, glad to see you finally opened your own thread instead hijacking one completely unrelated... kudos.

1. Could be there is too much air/pressure in the vial already... try to draw without injecting air.
2. Could be you are "equalizing" pressure correctly, but fail to flip the vial upside down to draw the oil/liquid... push air in to vial, flip vial upside down & pull oil/liquid.
3. Could be your vial doesn't like you and you sticking it even with air... dump your vial.

Is this the first time ever you are loading a syring?

Mostly likely air pressure and drawing air vs liquid.

Vented spikes equalize the vial pressure so you don't have to inject air into it, and draws much faster as a result.

Is this a serious post?

what do it mean?

what do it mean?

It means the vial is already filled with air and. pushing more into it makes the plunger bounce back.

i know i was just adding to the confusion itt

There's too much pressure in there broham. Put a syringe tip in there all by itself and vent out the pressure.

Nothing to worry about, its just the anti-penetration feature. My wife has the same thing.
