You sound to me to be the type of person to think that you can just take steroids and get huge.It just doesn't work like that.You've got to make sacrifices if you expect to get good results,in any endeavour you chose to undertake.
If you think making shakes is a headache,then you've got no business taking steroids in the first place.Not being an arse,but just telling you like it is.Oh,and for wanting the ready made ones,you'll be wanting someone to open them for you next,and then drinking them for you too.Geez,are you prepared to do anything yourself??
