Thanks for all the info
I been getting my syringes and needles from the Victorian Needle and Syringe program
They don't have the screw, more just press on. I only have 1ml syringes, I'm assuming I will need 5ml if I ever need to jab 1ml/250mg?
I currently use the 1ml, and fill to 0.4ml since my vials are 400mg = two shots a week of 160mg
But I can't imagine filling up my whole 1ml syringe for a 1ml shot
You can buy the syringes from Kogan / ozvials.com.au/ eBay/ glass vials Australia. You can get your needles from basically the same as above mentioned without eBay. Also sharps bins from all of the above.
