From my limited experience, and through reading the results of countless cycles, I've come to the conclusion that there is a maximum amount of gains that one person can achieve in a single cycle, no matter how many compounds they stack or how much they eat.
A lot of beginners (myself included) think that if a cycle of 500mg / week of test should result in an average gain of 25 pounds while on-cycle (not what you retain after you finish), and an equal amount of deca should result in 15-20 pounds while on cycle, then by stacking the two you should be able to gain 40-45 pounds on cycle.
Of course, anyone who has done a few cycles has seen that this just doesn't happen. It seems to me that the maximum gains the average person can achieve on a cycle is 30 pounds no matter what they're taking (this includes water weight, which I believe is minimal because most people regularly take AI's. So the gains have to be primarily muscle if the lifter is eating clean calories). Usually the gains come fast and furious at first, but begin to taper off by week 6 or 7. Your weight skyrockets in the initial weeks of a cycle, but after these gains level off the quality of muscle increases. The shapeless mass you pick up initially begins to get chiseled, more defined. If you look at the pictures of guys who have documented their cycles, you see this quite clearly. After about 8 weeks, they've gained all the weight they're going to gain, but by week 12 the muscle looks much harder and more defined.
In my humble opinion, it might be best to stick with simple cycles of no more than three compounds - two injectables and maybe an oral. I'm not sure if there's any value to stacking any more than this.
However, in addition to a person's gains on-cycle, one must consider how many punds of LBM they retain afterwards. Again, is there really an enormous difference between a cycle of test and deca, and a cycle of test, deca, and Dbol in terms of LBM gains after the cycle is complete?
What do the more experienced vets think? How many of you have gained more than 30 pounds while on-cycle? Do you agree with my observations, or have you come to different conclusions from your own experience and what you've seen on the boards?
