Most likely it's okay. Actually, I got some valid liquidex from a guy that everyone on this board orders from and even my shit settled after a little while. Keep it in the fridge at a normal temperature and shake it up all the time. The liquidex I got was 4mg/ml also, but I think that's too...
Go for the d-bol. Just expect to lose a bit at the end. I've never gained that much off Test and EQ together. I get more weight gain from deca than from test.
