there is no 200lb natural at 5-6% at 5'10 or less. never met one,, never seen one,,,never trained one.
adonis is basically where it stops naturally,,,maybe 10-15 more pounds if! he is in his early to mid 20s.
i have trained with few natural "freaks" that experiemnted with winstrol/anadrol/dbol tablets for short durations (i consider them natural since they didnt know a from z),,the freakiest guy i have trained with from this group was 6'1 225-230lb 10-11% with extra ordinary muscle shape and 19.75 inch arms. ofcourse he was on every pro hormone you could find on the maket and was eastern europian.
any bodybuilder at 5'10 or less that enter a gym at 200lb 6%,,,will walk around offseason at ~ 240 10-14%
anyone who tells you something else lies to your face.
