51 yr old male
lifetime natty
5 weeks out from competition
debated test/aas in the past but still chicken to do it

I compete in a natural organization and this may be the last show for me. If so, I want to do something a little stronger than creatine, lol, but not ready for test; thinking sarms may be the answer for me.

Anyway, in 5 weeks I'll be around 6%.
My question is, is there a good time or a bad time to start a cycle of LGD4033 or MK2866? (still not sure which I want to go with)
Meaning, is it better to start at low BF or better to let my system come back a little before starting?

Am I overthinking it?
