Maybe an outdated concept these days but u really need to experiment with different compounds one at a time to see how ur body respond... this is invaluable knowledge not attained in any other way.
most have no patience for this, and simply jump on multiple hormones from the get go... like dummies
Lol, yes outdated. Old timers used to tell me to switch up things every 2 weeks or so.
But yeah, I used to do one compound for 3 weeks at a time and then switch...get to see how your body responds, longer esters I'd hit for 6 weeks then switch to cyp, omanadren, sust, or e.
You'll learn a lot from doing the above about what works for you.
Least favorite anabolic is deca - I would get moon face from it even when dieted down.
