The popular belief is that trenbolone is a cutting/bulking substances, which provides lean gains; however, any real trenbolone user (particularly the popular trenbolone acetate version) will tell you that trenbolone injections every day are not reasonable. It’s not possible to inject yourself daily with trenbolone unless you have an unlimited pain threshold (no one we know does); thus, it’s more reasonable to add trenbolone to an already existing steroid cycle such as Testosterone and Dianabol. On top of the daily injection problem, trenbolone is known for being terrible on cardio shape of the user. Imagine being 250lbs. and running out of breath on the 4th step of the staircase (or 2nd set of a workout), well that’s what happens with trenbolone use. Cardio shape is diminished terribly with trenbolone.
