no you wont have toxic problem,,even if you took dianabol for 3 months in a raw,,,you are not abusing it for 3 years none stop,,,nothing will happen.
i recomend the break simply to give your liver a rest,,,and to get your body off it,, so it can repond better to it again 5 weeks later. past 5-6 weeks the body doesnt repond to dbol no more. some stop reponding after 3-4 weeks,,,it all depends on how much lean muscle mass you got.
icn is ok,,its human grade and i dont use it because i dont believe in products that come from the good ole yugoslavia,,they fucked up on product way too many times in 2001 for me to even look at them again.
all in all the recent tests show they are ok and they are indeed human grade so i approve them.
personaly i would use norma hellas test or testovirons from protugal,,but any human grade will do.
