Bold cyp/bold ace would be for anyone who wants to use boldenone but for whatever reason doesn't want a long cycle or a substance that hangs around in their system for a long time for testing considerations. I personally feel like the effects of test prop are stronger than slower test Esters (granted my experience is limited), because your blood concentration is increasing at a faster rate than with something slower. I would suspect a person who had used both EQ (undecyl) and cyp to report that cyp "felt" stronger at the same dose bc it will build to its peak concentration a lot faster. Ofc uts the exact same anabolic, though.
