I used to have about 1.5 scoops about for 3 gyming sessions per
week, eagle told me it was too much, dropped down to 0.5 scoop.
Can't remember what exactly, stopped taking it altogether.
My workout isn't that intensive but I get by, i compensated not
taking protein by having a proper diet, helped again but eventually
hit a plateau.
Come Hougang Gym train squats with me every Sunday lah 
40 mins gao dim... Recently I cutting, so reached 77kg, still
doing 120kg squats... Like that then I take that wee bit more
supplement....
When I was still doing 80kg to 90kg squats, I wasn't taking
any...
