NO NO NO NO NO NO NO NO!!!!! that would be a very bad idea, my friend. M-Drol is an extremely potent compound. like Superdrol, it delivers fantastic gains but also fantastic sides. 4 weeks seems excessive to me, i would recommend a shorter 3 week cycle at 10/20/30 or 10/20/20. it seems that most users of this compound experience the majority of their gains around week 2, then gain slightly more in week 3 (however the sides this week tend to outweigh the gains). an additional fourth week would be overkill and i don't suspect you'll gain much.
regardless, adding in yet another exogenous hormone following your run with Superdrol would not deliver you any further gains. it will only shut you down even more and exacerbate sides. def save the Epi for another cycle.

generally speaking, with methylated orals the longest youd want to go is 6 weeks. but 4 weeks is all you need. more is not better here.
I'd recommend a three week cycle of M-Drol. I did a three week cycle of Superdrol and the third week was almost unnecessary, so a fourth week, in my opinion, isn't worth the side effects.
During the first week I'd run it at 10mg ED for the first 3 days just to see how you are affected by it (you never know if you're going to experience some kind of reaction). After the first three days, if you feel normal, then bump it up to 20mg ED for the duration of your three week cycle. I wouldn't bump it up to 30mg ED because more than likely it's not going to do anything different for you than the 20mg ED would, except for increase the negative side effects (lethargy, lower back pumps, acne, and messing up your lipid profile and liver enzymes, ect..). You probably won't start noticing the benefits of the M-Drol until around the beginning of the second week. During week three you can still gain some, but it'll start slowing down. Luckily strength gains will continue to improve during the third week, but mass gains will slow down. I recommend eating more than usual during the third week to potentate any possible gains. You should already be eating like crazy while on-cycle. More than usual. When I'm on-cycle I try to gain as much as possible. Eat clean, with good macronutrient ratios, and eat the right foods at the right times, but eat, eat, eat!!
