i have read some articles about nolvadex and clomid being toxic to the liver and prostate and cause cancer to them and also nolvadex to upregulate the progestron receptor making it more sensitive to nandrolones (deca & trenbolone), so thats why i was thinking about never using them again and use arimidex & aromasin instead even in pct...! what do u think guys? whats the best for on cycle and pct? give me ur personal experience and opnion!!!
