there is no such thing as 'reformulating'. There are not formula options outside of manipulating the concentration. What COULD be the case is that your second batch crashed.
I'll also add that when you 'drew clear' from your second batch, but the vial is milky/chunky white, it means that you didn't actually inject much, if any, test. It has to be homogeneous prior to injection. Otherwise, you're just injecting the carrier, not the test. Your dosing is going to be all fucked up, lol.
