LGD + RAD140 + cardarine would be a really good stack. You can start the stack as soon as your are done your mini PCT
I would do a 12 week stack like this -
Weeks 1-12
LGD 10mg/day
cardarine 20mg/day
RAD140 20mg/day
After your cycle, run a bottle of a good natural testosterone booster like HCGenerate ES from n2bm.com as a mini PCT. SARMS are only minimally suppressive of natural testosterone production
here. We are talking like 5-10% suppression. You don't need to use a SERM like clomid or nolvadex in your mini PCT. It won't hurt you either but it isn't needed.
This is the stack I recommend to any of my clients who are experiencing joint pain -
A good joint supplement like n2joint rx from n2bm.com + 25mg ostarine + 3-6g of a high quality fish oil per day.
You could add the joint supplement stack into your 12 week LGD + RAD140 + cardarine cycle.
