lgd4033 vs. rad140 the truth

I’m looking to make a decision on which sarm to use and I’m boiling it down to a decision between using lgd and rad.
And either situation I think I’m gonna go with 15 mg a day with some gw501516
My main goal is more energy in the gym and more muscle mass.
I’m 5’9” and I’m 185 lbs and 28 years old
