people talk but...

people talk about after 3 weeks sus 250 starts kicking in...when they say that..does that mean i will start noticing mass coming on or will i juss start feeling extra pumped??? cuz i juss finished one week and i feel bigger :D...im prolly juss siking myself out, but i have also been busting my ass a lil harder in my gym!!....Juss wondering ..if there are any other fellow sostenon 250 user i would appreciate a response?

i start feeling extra pumped the second i take anything - that's the mental part

you'll start noticing the weight gains, muscle strength increasing in 2 - 3 weeks usually.
