I get all my stuff from GPZ Services.
However, after I mix my HCG with 1ml of solution, I just keep it all loaded in a 3cc IM syringe in the fridge. When it's time to pin, I use a slin pin and draw what I need from the IM syringe, than inject. Simple.
I'm just telling you this as you can get away without using vials. No need to place an order just for vials alone.
