Oil left in the syringe

[fbodyguy02]

I drew 1 cc of Test E in a sryrine, then changed the pin before injection.. but ended up with around .9cc left after I pushed the air out of the new pin.

After 10 shots, thats 1 CC worth of gear! If you shoot .9CC of Test E 250/mg... thats only 225/mg your injecting! I'll quite my bitchin now.

i always pull the plunger back a notch before injecting...seems to empty syringe better.

I draw a little air back into the syringe prior to changing pins. It sucks the oil out of the pin and you don't waste it. I'm sure there is still a microscopic amount of oil wasted...but COME ON! lol

You'll always loose a micro bit as mendo said, Well I shouldnt say that someone here probably has the shit down to a science a preserves everything..But hey the man that has that figured out is me......

Are you saying that after you draw the oil into the syringe you just unscrew the pin and switch it leaving oil in the first pin? I hope thats not what you mean. When you switch the pin, draw back on the plunger to get pull back the gear thats in the pin so that you dont lose any.

It's called needle "waste space" and is an unfortunate part of the design of most syringes with replaceable needles. The plunger cannot occupy the nipple portion of the syringe where the needle attaches when depressed accounting for the lost gear. The US Pharmacopeia recognizes this and recommends that all US drug manufacturers overfill their bottles to account for the waste. I believe a 10ml bottle is expected to be dosed so that you use 1ml per dose and the waste space is 0.1ml per dose so a US bottle should have 11ml per 10ml vial.

There are some new needles on the market from BD that are considered low waste space but they're expensive as hell. Insulin needles would also be considered low/zero waste space but they're obviously less than perfect for larger muscle groups.

That's why I always have an extra bottle of everything I am running for that cycle
