I'm gonna disagree here. If this were true, then why is it called the "fina cough" and not the "roid cough"? They all have BA in them. Granted, you can get the cough, tightened chest with other compounds, but it is extremely less severe and very rare compared to fina. That may be the BA, I'm not sure. But the severity of the fina cough is caused by the compound trenabolone which gives a pnuemonia like cough when the compound enters the bloodstream and makes it to the lungs.
Also, I would never make anything without BA, BB isn't going to provided the sterility reassurance that BA will. BB simply helps hold the compound into solution.
