I read tht clenbuterol has a positive effect on fast-twitch muascle fibers. Does anyone know if theres any truth to this? If so, how long is it effective for this purpose?
I once heard that Clen had the effect of turning slow twitch fibres into fast twitch over time (I expect some type of continued use), but can’t substantiate that. I believe it helped me pack on some muscle, but I can’t say for sure as I started eating a LOT more at the time too… [shrug]
