it's important to start with a solid base and only make one change at a time and see what that does.
I can't stand to see guys run 500mg test and 500mg deca or whatever and eat 4000 cals a day then bump the test to 750 and swap the deca for 500 mg of somthing else then add 50mg winstrol a day and cut their calls to 2500 and say "damn his cycle rocks"
keep the drugs the same and change the diet , evaluate what happens then change one thing and evaluate and see what happens
I can't tell you how often guys will change 3 different compounds , add HGH and T3 , add 30 min cardio and cut 1500 cals then say how awesome ONE of the compounds is , their is no fucking way a guys can tell what did what when he changed a dozen things.
I think when we all got/get started with this we tend to over think alot of stuff and want to make it alot harder than it needs to be.
This is a major reason I'm a big advocate of hiring a trainer , it allows use to not need to over think as much as we do and gives us an opportunity to learn alot about what works and why.
almost everybody I know that has tried on their own then hired a coach ended up saving money of supplements and gear , lowering their dose and making gains WAY faster than before
