Left is real deal dbol from Thailand and sometimes strength of blue tab is underdosed due to no standards for the camel jockeys over there. Not sure on winnys. A test people say for dbol is tiny piece on a plate then eyedropper a drop of liquid boric acid which is drain cleaner for plumbing.. Never tried it though .. If it turns purple then it's real.. Try it ! UPDATE.. SB labs pharma makes the winnies .. They're real deal.. Can I have some .? Lol
