Depends on the goal, I am assuming you are trying to bulk with this selection???
LGD - Strong bulking sarm, you will need a test base, you can do it without it, but you will be lethargic. Run 10mg per day, and you will need a proper PCT (SERM).
MK677 - I've never takin it... its not technically a sarm, but from what I hear it will send your hunger through the roof.
Orig1n - This is natty, no where near the gains of the two above, but there is no hormonal fear, nor a need to run a PCT/on cycle...
My two cents on SARMS, they have not made it through all the clinical human trials, so no one know what in the world they will do to you in the long run. We only knows the immediate, which is similar to PH. Crush your lipid panel, drop your sex drive (test) etc. SARMS are by no means the "safe" alternative that people originally advocated when they first became popular.
