im no expert, but im definetaly younger then you and i blast and cruise
i started doing it after having the same dilema as you
all i can say is ive definetaly been able to maintain my size all year round and continue to grow
HOWEVER i should point out that blasting and cruising on 250mgs isnt the end of things, or the anser
eventually u will gain more size and strength, and ur cruise of 250mgs a week wont be enough in order to maintain ur size
many guys seem to forget this and think 250mgs is enough to cruise on forvever
i can assure you if you successfully blast and gain a good solid amount of strength and mass, after 1-2 blasts ur gonna have to bump up ur cruise dose
i know i found this to be the case, and im sure many others have
it all depends on how big and lean you really wanna get
another thing is I ALWAYS see guys (like you, and myself actually) say ' i wanna blast and cruise just 1 or 2 times to put on some serious size then come off'
this almost never happens, for 1 main reason
once ur at a level where you need to start blasting and cruising in order to keep gaining size, the size you achieve is never naturally maintainable, and the feeling of being on is addictive
so you need to consider this
remeber your i dea is to blast and cruise becoz the size u wanna achieve isnt possible if you cycle on and off
so do you think after you blast and cruise your going to maintain any of it? your just going to go back to ur natural genetic potential and eventually where u wouldve been if you had cycled on and off
blasting and cruising isnt a short term decision, its a life time decision, or something you pursue if you wanna stay on for a long time (years) then come off
and considering how uve spoken to people in ur gym who blast and cruise who seem like theyve been doing it for years, i would say this holds wat i think true to a point
APOLOGIZE for the long post
