I would stack LGD and rad140 with a PPAR regulator like cardarine or SR9009 rather then ostarine. Ostarine is great for recovery but your recovery will already be awesome if you are using LGD and rad140. A PPAR regulator like cardarine or SR9099 will directly increase fat loss and endurance of your cycle. Stacked with LGD and rad140, you will get a nice increase in strength, endurance, fat loss and recovery.
You don't need to use a liver aid supplement with your cycle but adding it a good natural testosterone booster will help keep suppression of natural testosterone production to a minimum. Rad140 is one of the most suppressive SARMS so using a testosterone booster with your cycle is a really good idea.
This is what I recommend
Weeks 1 - 12
LGD 10mg/day
RAD140 20mg/day
cardarine 20mg/day
HCGenerate 5 capsules/day
After the cycle, run a mini PCT. 4 weeks of the following:
Clomid 25mg/day
HCGenerate ES 5 capsules/day
