Either cycle sounds good to me. 6 weeks is not too long, as long as M1t is only 4 weeks or less. But many guys are shut down pretty hard from 4 weeks of M1t. It depends how you react to it. 4 weeks shut me down harder than any cycle in recent memory.
You could do Option 2 & run 4ad alone for 2 more weeks at the end. 6 weeks will make a better bulking cycle for keeping gains.
If you have liquid nolva- 60mg/50mg/40mg/30-40mg over 4 weeks. If you have tabs, use 40/30/20/10-20.
