How much muscle can you gain naturally?

Lessons learnt from this video https://www.youtube.com/watch?v=GMTMAPw3ajs

1) less than 1% chance of looking decent naturally
2) most youtube fitness celebrities are liars
3) you are wasting your time if you are not on gear... I find this to be somewhat true when I look around and the amount of people who haven't changed after 6 years is astonishing high

Lol, the idiots in the comments hating on this guy... Keep getting ripped off by buying whey protons, creatines and test boosters, they all deserve it.

Pick two....

1.Big
2.Lean
3.Natural

Anything else really requires AAS with the exception of godly genetics, which would still limit you up to a point.
