1st cycle advice guys SARMS

Hey everyone,
I just need your advice guys on sarms really,

I stopped lifting since feb 2016 and started today

And i wanto start a sarms cycle but I'm really confused about it as i never been into cycles in my life

So i was thinking about mk 677 and something like ostarine, but am not sure about them, can i start botha them together or shall i make my body get used to sarms with one product for 1st the cycle (4weeks) and after that i can use two along?

And also PCT !? I have no clue what it is based on really

And i was thinking about starting the cycle after 2 3 weeks from today, what do you think guys ?, would my body tolerate that ?
