It is UG test e. There are maybe 2-3 shots left in the vial and I noticed these. I noticed them on my last vial with about 1 shot left. I injected it anyway and no knots or infections. It settles so I can minimize how much I draw but I definitely injected some.
Let me describe it: You know after you change the Brita water filter in the Brita water pitcher there is black stuff that settles at the bottom in the first couple pitchers. It looks like that but really, really fine and small.
Could this stuff be from the gear filters? At least I don't think it is microbial, so I am hoping the BA sanitizes whatever it is. I just worry about this stuff being taken up in my bloodstream.
