Ask yourself this question... what's more keepable in terms of gains... 15-20 lbs. of weight that has a lot of excess water, bloat, estrogen, albeit, a lot of size and some of it can definitely be keepable but definitely a lot will be lost when estro decreases and water dissipates OR 5-10 lbs. of dry lean muscle gain... Don't kid yourself into thinking that winstrol and anavar are only used as finishers... that may be the most popular way to use them and more common but definitely not the only way... the gains you get from winstrol and anavar are very keepable.... masteron is definitely a bit harder because its basically a pure aesthetic in terms of gains but you need to be at the proper body fat to even be using it anyway.... trust me when i tell you, anavar and winstrol are not just for hardening... strength can be very big on both and you can most definitely add lean muscle size... its definitely not something extremely drastic but i assure you that 5-10 lbs. of lean muscle is attainable on either...
regardless, keepability depends on YOU... too many guys feel like everything is dependent on what your running... yes, they are certain things that you just cannot do without steroid type gains and effects, i completely agree with that but there are plenty of things IN YOUR CONTROL as well...
anything you use or run is dependent upon what you want to accomplish, your quality, your discipline, etc... you can make a multitude of gains and keep a lot of it on anything you run... some definitely more than others, it just depends on so many variables but winstrol and anavar both are amazing and definitely have a place on any cycle...
