1wk-200mg
2-8wk-400mg per week
9wk-200mg

winstrol- 200mg per week throughout the cycle.
he wants to know for 200mg can he do that in one shot a week or break it up, also with 400mg per week? he asked me and i have done it before so i dont know. that is why iam here asking the fellas. take it easy and thanx!!
p.s. i told him about test but since this is his first he just wants to be safe about it.
