Test E pain and possible solutions?

Is cottonseed oil considered a sterile oil? I need to find something to mix with my Test E because it just hurts way too much.

get b-12 it will be better

B-12 comes in an oil form?

yes you can get liqued

Are you taking anything else?

No. I was mixing it with deca and that worked fine, but that bottle has run out. I just need to finish up the test. Can liquid b-12 be bought at a pharmacy or gnc?
