I have done several cycles with Deca, dbol, anavar, prop, winny and Eq and have never experienced tingling. It is now the end of week 3 of a 50/mg day Tbol only cycle. The last couple nights I go to bed and my right leg falls asleep and then the tingling moves throughout my entire rights side. My head is the only part of my body unaffected. Fortunately, the tingling only lasts 20 minutes or so and then everything returns to normal. Kind of scary I admit. Anyone else experience this side effect? Anyone know the cause? I am hoping this is not a big deal since Tbol is treating me very well otherwise.
