I read a guy's log who used a SARM for pct. after a few months, he got his blood work done. his testosterone came back around 220ng/dl.
SARMs suppress your HPTA, there's no doubt about it. go ahead and use them if you want, no one will care.. but you might as well just continue using aas.
as for peptides, if you want to use DAC, I would suggest looking into adding GHRP-6 (or 2) to it and adding huperzine.
search around google for dosage protocols.
