Thank you very much for your reply.
I have big respect for your knowledge and all of your articles.
I read a lot of them and think they are very interesting.
I would like to let you know that I live in England but I am a dutch guy from The Netherlands.
I always order my gear from Holland and over there the pharmaceutical concentration of testosterone entanthate is 250mg/ml.
It was my intention to make 250mg into 1ml.
You're absolutely right, no water has been used.
That's why I started thinking what else it could be and I think I know.
The whatman filters I use are not sterile and because of that I need to flush a bit of rubbing alcohol through the filter to make sure it's sterile.
Do you think that that could be the reason?
It was just a bit cloudy, not much.
