Ok, yes, nothing noticed, no soreness at all in particular, rather even feeling of its reversal when I use Muscle Roar and quite fast, if I think about it now, but no growth.
I will check, no idea about limiting beliefs, I mean if I can quantify presence and effect. I presume it’s related to lifestyle, but if think that I didn’t give enough use - will do 2h on phone speaker daily. But now concurrently will return to old routine too or rather enhanced version of it with paid fields like Motion Mimic.
As per protein, doubt that 300gr isn’t enough 
, I’m not eating meat, fish or eggs (almost), but this should be sufficient to cover all needed amino acids anyway.
