If you are really prone to it, there is a chance of it. But even then ... its not very common. What dose of EQ are you running? EQ + Var is a very beautiful and fairly safe stack. I would say that unless you are very prone, anything under 600mgs.wk you wont have a problem. If you are prone, and its a big worry for you, I would go with NPP, or a small dose of deca. I would rather use the NPP than Deca.
The 2 safest injectibles for the hairline would have to be Nandrolone, followed by EQ IMO.
