I'd run the M-Drol by itself for a three week cycle, and if you feel okay after the proper PCT, then run the stack. M-Drol is a superdrol clone, making it some of the most potent **** out there, and can also cause bad sides. Personally I just finished a three week cycle and my only sides were some moderate acne.
Try 10/20/20 on the superdrol and do your PCT. Because some people react differently to different PHs, I really suggest running the SD first. If you eat right and lift properly, expect to gain around 15lbs of dry muscle mass.
Tren is a different story. I won't go near the stuff personally after what I've seen people say about it. Some people love it, but a lot of others say it gives really wet mass, terrible sides, and shuts you down.
Good luck man, hope you enjoy your cycle.
