can anyone please suggest a suitable diet while on winstrol 20mg/day? by this I mean, amount of cards, protein and fat...

A friend of mine is taking that amount for 50 days. It's been a week now and he's afraid that the pills are not working somehow...

what should he eat? The main aim is to cut and get a lean body

stats:
height: 167 cm
weight: 63kg
training experience: 2 years
steroid history: 1 course dbol about a year ago

please, do not ask me why he wants to get lean being at 63kg. From what I can see he still has visible fat which has be removed for a better definition...

thanks in advance
