It's impossible to say what effect it going to have on you as opposed to someone else.
Personally if you can do a test run i'd shoot half and see what happens. If in a HR or So you don't see what you want shoot the other half.
I've seen guy that were pretty vascular shoot all 10ml and expect them to look freaky but only end up with a moderate increase. Then I've seen guy that were reasonable vascular get all freaky looking from 5ml.
I think it has ALOT to do with what your body is doing , if you are somewhat depleted and drying out you probably won't get the same effect that someone who has been carved up and hasn't had to cut water to much.
I've seen guys get some pretty damn impressive results just from taking Viagra and a little red wine , then I've seen guys that couldn't get veins to pop or get a pump to save their life with anything from being dehydrated and depleted
