I run my syringe under hot water to just thin the oil out so it goes in smoother.
some oils are thick as fuck... ive had a few different brands on enth where ive had to warm the vials under a warm tap or id be trying to shoot for 5 mins!ive got a few boxes of cidoteston left that will have to be done the same way when i go back on... oh, and ive been off 5 weeks and im down 21lbs
i used to when i first started out and had some really crappy test. it was brewed up well above the point of what the solvents could hold and would crash a tiny bit, giving PIP for a few days post injection. heating it and then cutting it with EQ seemed to help a lot. now, i don't feel the need since nothing i use can't flow through a slin pin.
