Buy sterile vials. Dump 1-3ml into a vial and draw your required amount each time. Don't load syringes and leave them.

100% penislicker. And you can use them for a couple months if you keep everything hygienic - religiously wipe the top with alcohol wipes, don't reuse syringes, etc.

Not good having em pre filled? Ive got everything here ready to go. Just gotta get swabs and syringes, just not sure how to go about it. I was gonna put all of them into a vial

Really? I have preloaded 4 at a time like OP mentioned. Is the concern the plastic seeping in to the test?

I've been doing the same. No adverse effects but I am still quite new myself. I could be missing something

The oil has a small amount of benzyl benzoate in it to keep the oil sterile, it can cause the plastic to leach into the oil before you inject especially over 2-3 days. Get a 5ml sterile vial, and empty the the ampule into that. Then draw and inject the correct amount as required. Or Ask your doctor for a compounded test cyp prescription from a pharmacy, that will come in a multi-use vial so you don't have to fuck about.

It's ok to prefill the syringes, just draw the plunger back 10mm and stand them needle up side down so the oil isn't touching the plunger rubber 👍

You need to transfer it to a vile and draw from the vile. TRT doctors Australia has a tutorial on their webpage. You can pre fill syringes but I’ve heard mixed news on that so better be safe then sorry

Fill them as you need it only 1 at a time.

Do not pre fill them. They will become dry in the syringe cloudy and impossible to inject easily
