the gains for me started around the 3rd to 4th week. week 4 seemed to give me a growth spurt. i have been gaining every week since. sex drive increased in the 2nd week. the pumps seemed to gradually increase and they are at a point now that when i finish a set of say leg extensions i have a hard time walking to get a drink. the pumps i have been getting are ridiculous! i was worried at the beginning about getting bloated but that has not been a factor. i love test.
