Keep in mind, Test E half-life is 4–5 days. So 2x a week already keeps things stable. The “spikes and dips” aren’t as dramatic as with short esters.
I’ve tried 2x and 3x zero difference in sides, mood or strength. The only difference is more scar tissue.
Personally prefer 3x a week because I combine with other compounds. Makes the math easier to line up everything on the same schedule.
Don’t overthink it, man. 2x a week has worked for decades. If it isn’t broken, don’t fix it.
I’d say 3 times a week for smoother levels less fluctuation and more consistent energy. Keeps the sides in check too. Trust me you'll feel the difference.
