Checking the exact amount in the syringe

[Royal244]

Hello. Does this way i am about to write is good in terms of checking the exact amount of testosterone that is inside a syringe? I am filling a syringe with a little bit more testosterone than i need, then i squeeze most of air bubbles (and some testosterone with it) into a vial from which i retrieved testosterone so i wouldn't even waste a drop, during this process i am now watching very carefully at lines in a syringe so i would get the exact number i am looking for. Immediately after that i am injecting. I am doing 50mg every 3 days. Syringe ready to injecting is filled like on the picture. Thank you.


P.S Also, i have another question - often after squeezing air bubbles and preparing myself to injection, i see that some of air bubbles are not in a syringe but instead inside the needle (on the area where you put it on a syringe). I am not squeezing it, because i don't want to lose testosterone, so i am just ignoring it and insterting the needle into a muscle. Am i on a safe side here?

Are you really using a 5 ml syringe? The picture you are using is that of an oral syringe. It would be much easier to use a 1 ml syringe. Is the volume of your prescription 200 mg/ml or 100 mg/ml?

Yeah, i am using 5ml (i am using the exact same syringe in fact)
There's 100mg/ml.

If you are injecting SubQ or IM you do not need to worry about small air bubbles. However, if you were to inject in a vein that would be quite a different matter.

Well, that sure looks like an oral syringe to me so you must be using a similar ssyringe but different. Look at your prescription or the vial of testosterone. Does it say "200 mg/ml" or "100 mg/ml". The volume/concentration makes a huge difference on how much you should be pulling into the syringe.

So, i shouldn't worry about the air bubbles then. I mean, the air bubbles can not get out of syringe during the inserting process, right? (without pushing the plunge of course) Because i read that i could hit a blood vessle before i reach the muscle.

It says 100mg/ml. It comes in vials.
I'll look into 1ml syringes. To be honest i have no idea if it is an oral syringe. Would that be a problem if it was?

If the concentration is at 100 mg/ml then your picture is accurate. I think most of the concentrations being prescribed these days are 200 mg/ml. If that was the case it would mean that it is twice as concentrated and you would only fill the syringe up 1/2 as much as you did in the picture.

There is nothing wrong with using a giant syringe, like that 5 ml they use on animals. If you can get a needle on it then go for it. What size harpoon are you using with that syringe? If you're comfortable using that big boy then it's okay and will get the job done. You'd probably like the 1 ml much better though and the markings/numbers are spread out farther. It actually makes it easier to be more precise which seems like you want to do.

Most people are using anywhere from a 27 gauge to 29 gauge 1/2 " syringe/needle such as this Easy Touch Insulin Syringe as an example, but many other companies make the same type 1 ml syringe.

Don't you laugh at my 5ml syringe. You're going to make me leave to a bodybuilding forum. Although, maybe not. They would laugh that this syringe is too small.

But really thanks for help. I am going to buy 1ml, because like you said i wanna be more precise.

 

[MarkM]

Don't be disheartened, I'm just having fun. I started off with harpoons too. It wasn't until my daughter saw the syringe/needle and ask if I was giving the livestock injections that morning that I changed to a much smaller syringe/needle.

Never heard of anyone using a 5ml syringe.....people who use/abuse testosterone/AAS are using 3ml syringes due to the (higher doses/volume of oil ) used for bodybuilding purposes.

Men on trt are using far lower doses/volume of oil when injecting.

If you are worried about waste than use 1ml/.5ml insulin syringes (fixed needle) as they are low dead space and minimal amounts would be wasted.

If you draw properly you should have virtually no tiny bubbles and will end up with one at the top just before the needle after syringe is loaded and it is easily pushed out back into vial.

Don't feel bad. I used to buy 5ml syringes also because nobody tells you anything, including your prescriber. I just went to CVS/Walgreens and asked them for a syringe that matched the gauge I was recommended to get. It was only on here, starting in June, did I learn about the 1ml syringes. The 1ml are so much better and accurate.

Would that be fine? If i am using 19G 1½ (1.1 x 40mm) needle to draw testosterone and 22G 1½ (0.7 x 40mm) needle to inject? Would these needles fit into that syringe?

 

[MarkM]

If you get an insulin syringe with a permanent needle, like I mentioned earlier in the thread, you will not need to swap needles to draw and then to inject. You can use the same needle for both. The insulin syringe will eliminate the waste you get when you are swapping needles. Over time, you end up losing a good bit of testosterone left in the syringe. A 22 gauge 1 1/2" needle is way bigger than you need and will leave more scar tissue than a 27 to 29 gauge 1/2".

 

[madman]

One could use a 19G to draw but with that size of a needle you are just going to end up hacking apart the neoprene rubber stopper and the chance of getting bits of neoprene rubber falling in the oily solution (vial) are very high.

If anything a 25G to draw would be more sensible although again most on trt are using insulin syringes (fixed needle) 27-31G to draw/inject as insulin syringes are low dead space so less chance of waste and also because the needle is fixed you can draw/inject same needle avoiding hassle of changing needles and to top it off less scar tissue compared to the 22G harpoons.

Sure draw/injection time with insulin syringe may seem much slower compared to a 22 G or 25Gbut it is way more convenient.

Why harpoon yourself? 1ml Insulin syringe with 1/2" needle does shallow IM or SubQ depending on injection location and your technique. They can be had for around $0.10-0.15 a piece in boxes of 100.

What problem(s) can it cause?

What about using the 22G 1½ for injection? Is that ok?

I thought they were too short to be used for IM injection. I mean, the 22G 1½ needle i am using to inject goes all the way inside and it's pretty long.

You don't want neoprene rubber falling into your testosterone solution and somehow work its way into the syringe and then into your body. The risk isn't worth it.

Yes, you can use a 22G 1 1/2" for injection if you want to use a harpoon.

1/2" needle is not too short unless you have an extreme amount of body fat.

We are just trying to help you. No sense in making larger holes in your body and therefore more scar tissue. If you want to use the 5 ml syringe and harpoon needles please carry on. They will get the job done.

You will find on this forum abour shallow IM. That´s very used by many of us.

 

[madman]

Do you really want tiny bits of neoprene rubber floating in the oily solution and chance of drawing any into your syringe?

Again of course one can use a 22G 1/2 inch when injecting but a 1 1/2 inch length needle is commonly used for (old school method) glute injections.

Testosterone can be injected sub-q, shallow i.m., deep i.m.- what ever suites your fancy and 1/2 inch needle length is common for men on trt.....some also prefer 1 inch (if not using a fixed insulin syringe).

Also keep in mind that many on trt inject more than once weekly as twice weekly (every 3.5 days is common) and many men with low/lowish SHBG are injecting daily or EOD.....using a 22G would be a nightmare poking yourself frequently.....unless one likes that sort of thing!

I would rather not. However, i am curious how dangerous that is. What can it do?

I know, thanks. I will change a syringe to 1ml. Also, i had no idea that you could use insulin syringe/needle to inject T. I mean, it looks extremely small.
