I'm interested in your height/weight.
If you have been gaining strength and mass but maintaining body fat that's not a bad thing really. However based on your post your overweight, and far beyond what you would like to be.
So diet is going to be 10x more important than a PED. However I think your on the right track.
To start out check out Ricks diet 101 post and put some time into comprehending and re working your overall approach to nutrition.

Now for the Cardarine.
Get it from SarmsX.com
Run it for 16 weeks.
1-16 GW501516 20mg dosed pre workout or in the AM upon waking on non workout days.
No PCT required for this.
I would highly recommend adding in Ostarine for your first go.
In that case your cycle would like this:
1-16 GW501516 20mg dosed pre workout or in the AM upon waking on non workout days.
1-12 MK2866 25mg dosed in the AM all at once.
PCT:
13-16 Clomid 50/25/25/25
13-16 GW501516
Good luck!
