and let me further qualify this by saying that i do not promote the 5 year on plan like cap eq mentioned.........there are logical ways to mainain hard-earned mass while in between cycles..........i would say it is realistic to spend about about half the amount of total cycle time off...........tht means if you are on a twelve week cycle.........at least try to take 6 off.........if you are working towards a specific goal, like a competition, and cannot afford to go into a catabolic state...........bridging with a low dose of test or deca works pretty well........a shot of cyp every week or two.
if you can afford it, a couple units of growth a day, is also a reasonable way to maintain gains........and when you start becoming a real student of the game........you will learn about bridging with t3, gh, slin or possibly 1gf-1
but something as simple a 30g of creatin a day will certainly have a positive effect.
