Yes many run AAS cycles then run Peps in their "off" time whether that be a PCT mimic or during PCT and there after until another AAS cycle or with an AAS cycle and Off cycle. Many ways to go about but yes it's common from what i've read for people to use peps in a means when off AAS.
Hope all is well brother.
I have been doing this for years. Peps (good quality peps) help with recovery, GH levels and protein synthesis.
I keep it basic, run IGF LR3,GHRP 6 , Frag176 and some kind of CJC.
