Hello, I bought some MK-777 (not 677) from umbrella labs, it’s the polycell formula and to me it seems it can’t mix correctly. I took it out of the bottle and used a frother to try to mix and it still seems there is stuff that floats to the top and sticks to the dropper. Is this normal? If not, how do I fix it? Thank yall so much! (New to this community btw)
