Been running cycles on and off since 2013 but decided to blast and cruise around a year ago. Cycles have been either test/deca or Test/Tren I have done 6-7 cycles if I remember correctly.
I personally like MK677 but it's best to run that for 6+ months to fully benefit from it. To maintain after cycle Iike mk-2866 paired LGD and some GW. You'll get some nice healing and the ability to hold some mass while cruising
It's best to run a stack of sarms while cruising til your next blast. Sarms are perfect with trt.
I use MK677 all the time on blast and during cruise at 25mg per day which is something you may want to look into for its GH boosting effects. It's good to run a good year or more at a time
As for other sarms during the cruise, RAD and LGD are perfect for gains in lean mass and strength. I'd stack those for 12 weeks and add in MK677 if you can.
