So I'm about a week into a test-e and parabolon cycle and tonight I noticed a very small dark particle in my test-e bottle. It's so small I've got to get the bottle up to a light source and look hard to see it. I'm guessing it's a piece of the rubber top. I couldn't think of anything else it could be. My pins are pre-assmbled, seald and packaged until I unwrap em to load up. It doesn't look cloudy but I do see some air bubles form in the bottle when I shake it. Nothing is leaking from the bottle. I've loaded up two pins for next week and they are perfectly clear. Is the Test-E ok to use?
