Okay to combine substances?

[STRICTLY-POONTANG]

Would it be okay to inject sustanon/ or test and tren together? Also either of those along with b-12. Can these be combined in one injection, or do they need to be seperate? Thanks in advance.

Test/tren fine together as long as the test is oil based. Do your b12 seperate water+oil = no no
