ah, if it's suspension then i have honestly no idea what can be used to cut it with.
the problem with suspension is the water gets absorbed much, much quicker than the steroid itself, so then you essentially just have the steroid powder left between your muscle fibers (if you can imagine salt, or sand texture) and that's why you get pip because the crystallized steroid then actually cuts the tissue and with real bad gear crashes you can actually have a lot of blood form and clot where the appendage starts to swell up like a balloon. i've had that happen in my calf when i tried injecting test-e, ended up with a giant swollen foot for a week, couldn't even see my ankle or walk on the thing for nearly a month.
