Syringe Waste...just suck it up?

[Dean407]

So, I'm noticing obvious "waste space" in the BD 1ML syringes I am using. As in, to get 50mg of oil, I'd need to overfill to say 60mg or even a bit over. Even with the plunger fully depressed the upper portion of the syringe retains the oil.

Does everyone just bite the bullet and overfill or do some of you guys use more expensive syringes like these:

Remaining product should be minimal, certainly nothing approaching 20%. Are you sure you're depressing the plunger all the way? The plunger seal is conical to conform to the neck of the syringe. The amount left in the needle itself is truly miniscule - I calculated the volume in another thread.

Squirt it out after you inject. Pull the plunger back to bring in air and then force it out quickly into the sink. You will see that it is typically just a few droplets that were left in the syringe.

There is far less in there than you think. It might equal two ticks on a syringe at most at the end of a vial, no big deal.

it's a negligible amount. if it bothers you there is a method of injecting which some do not agree with called the air-lock method where you purposely leave .1cc of air in the syringe. you inject at a 90 degree angle so the air bubble is on top and you inject the gear followed by a tiny amount of air to assure all of the gear is used. I personally think it's dumb because it's hardly sparing anything.

Ive heard of this method as well, and is most certainly something I would never do.

Dunno why the pic rotated, but it's more then a few drops stuck in there. Should I change the type of syringe?

I see, you are not only talking about what is in the space above the zero line, but the entirety of the needle as well, right?

That's left after depressing the plunger all the way? That's nuts... definitely change. These are BD 1cc luer lock barrels? I use excel 1cc sometimes and they don't have this problem.

 

[Dean407]

I'd say it's half of a .1ml left over after fully depressing plunger, or a bit more as I didn't allow time for it to drip all down.

Yes, they are BD 1ML syringes. They seem to have a long "neck" on them which is why there is so much left over.

You could always ensure there is no air in the syringe when you pin, then aspirate a bit more than you normally would (since you have to verify you are not in a vein anyway). That way you get all of it injected.

This is the same thing I was talking about a while ago. You just have to get over the fact that you're wasting a bit each time. I don't ever run out because of it though...

The whole you can die from a air bubble is over dramatized in movies. Put a little air in the syringe, just enough to empty the chamber out. I ask a dr and he said you literally need like 3cc of a instant air bubble to be injected before you even need to start to worry.

Ya good call, it has to be inject directly into a vein as well for issues to arise

i just had a thought. instead of air maybe bac water would work? as long as the oil is heavier than the water, the water should sit at the top of the syringe and be the last thing to be injected. idk just tryin to be innovative here lol. wouldn't hurt to try

I am using the standard BD needles and syringes. I just measured how much waste I would have by pulling air into the bottle after I filled the syringe to the proper amount and it was 0.02cc (so two tick marks). To compensate for this, I let two air bubbles in when I aspirate in my muscle (to make sure I am not in a vein) instead of just one. Doing this, I tested how much was left over after the shot and it was only a few drops.

Since insurance covers my test-cyp (only $12 for a 10ml bottle of 200 test-cyp), I am not really worried about waste....but as they say "waste not, want not".

I have the same thing when using BD 1ml syringes... The amount "wasted" is the same as shown in your pic, its about .05ml.

Solution? Get over it, there will always be a tiny amount that you can never get out that is stuck in the barrel itself and stuck in the needle, I always without fail have .05ml left (maybe a little bet less) when using the 1ml barrles but if you think about it it is a very silly thing to get worried about. At 250mg/ml, .1ml = 25mg, half of that is 12.5mg of Test.

Either compensate and add in an extra .05ml or accept the fact that you loose ~12.5mg of test which is fuckall and won't make a difference by very much at all.

lol

 

[Dean407]

Yeah, I just started to add a little extra. It does seem odd to me though as I suspect some medicines require very specific dosage. But for our purposes it's not a big deal.

Why not draw it back into the syringe and just put your drawing needle back on and squirt it back into the bottle?
