Steroids produced by company called Global Anabolic (Thailand) do not meet the label claim. It’s said 10ml per vial, but the actual content is less than that, between 8 to 9ml. Also 20ml vial winstrol is actually 19ml, not 20ml like the label said. These anomalies has been reported worldwide. Those difference are obvious for vial version because you can measure it by yourself. But for tablets version, nobody know. No doubt about the potency, this is real stuff, but their content is less than it should. Some of those who got many profits from Global Anabolic product lines saying that is caused by some of the oils left over inside the wall of vials or bottom glass vial (15% of them) and same things goes for other UG products as well, but this is not an excuse. 20ml is 20ml, not 20ml minus 15% like they saying.
