Suspension is excellent for finishing off a cycle (2-4 weeks). You'll harden up BIG TIME, but susp isn't for the faint of heart... many manufacturers' susp is PAINFUL (if you want it painless find some QFS stuff... well, if you're in Canada). Also, if you're a normally irritable guy, don't hit the susp.
And if you don't have a girlfriend/wife who is VERY sexually aggressive, talk to them before you use susp... otherwise they may be a little... uh... surprised. And sore.
