Vitor,
Funny you bring this subject up. I just received 100 50mg yellow winstrols and 50 50mg Orange Anavars from my source. I have ordered quality var and winstrol zambons in the past from him.
He says they are from Katonjeng Labs or also known as BK. He claims that people love them, that they are very high quality.
I am a little nervous because of the claims of NO 50mg anavar, so I am skeptical.
My 2 cents.
