Title: Easy Testosterone Cypionate Injection Fill Method Explained

Steady and Regulus, do you guys backfill your syringes or draw with another needle size?

I don't backfill, I don't prefill.   I just do it as I go.

1.   Wipe the top of the bottle with alcohol.
2.   Pull the stopped on the syringe back to the desired dose.
3.   Insert needle into the bottle, push the air into the bottle, and invert.
4.   Slowly pull back the stopper to a little past the desired dose.   There will always be some amount of vaccuum that does not fill immediately, but once you have pulled back to the desired dose, just hold the bottle inverted for a half minute or so and the vaccuum will rise to the top.   Then push forward.  At this point you should have the very close to the full dose in the syringe.  If a bubble or two remains, pull back a little, then wait a bit for the vaccuum to rise to the top, and push forward.  Sometimes you will not get it perfect but you can always get the bubbles to small enough that they are irrelevant, if you are patient.

I honestly don't know why so many people say they have trouble with the smaller gauges.  Yes, it does require a little patience because the liquid is more viscous than insulin, but really I have not found it to be difficult or overly time consuming at all.   But YMMV I suppose!

Great explanation Regulus:  I am going to put this in the Injection Method thread above.

I pretty much do the exact same as above.  I use a 31 gauge to draw and inject with.  Works pretty damn well, and I don't mind the smaller gauge going in.  My only disclaimer is that I am doing every day injections of 8ml, so it is a pretty small dose compared to what most are doing, but I am pretty sure I could fill a 50ml dose and be injected in under 5 mins...  I guess if you have to be quicker a larger gauge is going to be the way, but for every day injections I greatly prefer the smaller gauge.

Just for kicks I timed myself today doing a 20 unit (2.0 ml dose, 40 mg).  Took a little under 1 1/2 minutes.  No big deal.

Ha ha.  Not bad guy.  How fast can you do a Rubik's cube though?  That's what counts...

Blindfolded or straight up?   :-)

The main argument against the direct filling of fine-needle syringes from the vials is that the needles are blunted when they pierce the bung. I use this method for HCG (Pregnyl) because the low viscosity of the solution makes it very difficult to back-fill the tiny syringe. However, the higher viscocity of the T fluid is easier to control so I use back-filling for that.
The difference between the sharpness of the HCG and T needles is very noticable. The blunted HCG needles require quite a lot of pressure before they penetrate the skin whereas the T needles go straight in with no resistance.
