All good responses. All true.
Something else to consider though.
Muscle is difficult to maintain for 3 reasons.
They've been enlarged by water and blood and that goes away after a cycle.
The body no longer recirculates protein to the same extent so muscle repair isn't as fast.
testosterone is lower, therefore maintaining, or more accurately, continuing to manufacture more muscle mass, becomes less efficient.
Proper PCT is imperitive, of course, but there are 3 supps that can help in each of those areas.
BIG BLAST has creatine, NO2 and serum plasma protein which is far more absorbable than any other form of protein. Yes, it's a little more expensive but definitely worth it.
VIGOR increases blood volume to maintain fullness and pump.
UNLEASHED reduces SHBG which oin turn increases "FREE" testosterone so you can make the most of what you have.
It's practical. It's safe. And it makes sense.
