What is of note with propionate, is that users have successfully incorporated it into cutting cycles as well. Especially people who tend to lose a lot of mass normally during extreme diet phases find this useful. By injecting every two or three days and using only 50-75 mg each time, no notable water builds up (or at least none that can't be fixed with proviron, arimidex or winstrol) and no fat is deposited, allowing a user to stay relatively lean. So this type of testosterone can be used to keep gaining or retaining mass until 2-3 weeks out of contest time with relatively little difficulty. Its best use is in bulking phases to pack on mass.
