Hey guys
I'm having difficulty withdrawing my test prop from the vial.
I'm injecting the same amount in air that i want to withdraw in to the vial, but no matter what i do, even if he needle is fully immersed in the liquid when i attempt to withdraw i get a syringe full of air with barely any liquid in.
There also always seems to be negative pressure in the vial, i tried injecting more air in but still the plunger wants to be pulled back in? Suggestions please? quick reply would be grateful as i'm due to inject tomorrow morning
Thanks
