For years I still have these same questions about sust. Just how important are the stable levels that E3D or EOD offer? Are they such that the gains will be impacted to a great degree? Mood swings....? How much of a difference does it make if I am off a day on the short ester? Is it something that becomes more important with long term test cycling, or would even first time users be well advised to do the more frequent and stable injection schedule?
I made great gains my first two cycles doing 2X weekly before I really knew any better and felt fine.
The more I think about sust, the more I wonder why the hell do I still use it, yet every cycle I go back to it due to the gains I have made with it.
