I've been taking cycles of Pro's since i was 16 (which isn't a very good idea at all) but I know what I'm talking about compared to some of these other guys replying to your post.
You're running the M-Drol correctly but when I took it as if I was taking a cycle of the original Superdrol-
Weeks 1-2 - 20 mg
Weeks 3-4 - 30 mg
Weeks 5-6 - 40 mg
Another good stack to do besides the M-Drol with P-Tren is M-drol with H-Drol.
H-Drol is the Halodrol Clone and I've also stacked it with M-Drol.
Not only will you get the strength gains from the M-drol, but you'll now get improved size gains with adding the H-Drol to your cycle...
Now apart from M-drol, P-Tren, and H-Drol... Beastdrol is basically Superdrol but 50 % better than Superdrol.
You'll find yourself getting fast results... higher strength gains and higher mass agins... IN a shorter period of time.
The recommended cycle of Superdrol last for 6-8 weeks...
As for Beastdrol... the recommended cycle only lasts 4 weeks, and in those 4 weeks you'll see 1 of 2 things...
1. The same results as an 8 week superdrol cycle.
Or
2. Increased strength gains and size gains compared to an 8 week SD cycle in half the time!
Bottom line... Get your hands on some Beastdrol.
But Your M-Drol and P-Tren stack is good if you've only done 2-4 cycles...
