Keeping the gains after cycle is the hard part, very impressive, plus the fact that this was only your 4th cycle and you pinned short esters for 16wks, lots of pinningI will add that I have been off cycle for about a month now and used short esters and I have no lost much strength or size, lost a couple lbs on the scale but that is expected from water weight holding in the muscles.
I don't mind pinning everyday but after 6-7wks it does start to get old
