you talking about synthol or just gear?
whats the difference when inj subc to im for gear?
The difference is pain, pain and a little more pain.
This stuff's meant to be pinned IM. Sub-q is too painful and cumbersome. If I want to pin a couple mls a few times a week, I've got to load a dozen slin pins and spend hours shooting that stuff. Even with a really thin oil, it takes forever to push through. Not worth it at all.
I tried pinning sub-q and just bruised hardcore. I wrote it off as a failed attempt and tried a few different oils and spots and felt the same excruciating pain each time. IM all the way.
