Steroids like Anavar and Winstrol would probably be your best options for what you're wanting to achieve...Primobolan could also be considered but that can get pretty expensive. You'll probably want to include at least a low dose of testosterone with whichever one you choose. Not a lot, just enough to give your body what it needs. You could also try stacking with Proviron instead...it won't be nearly as effective but a short run of say Anavar and Proviron followed by PCT will give you the results you're wanting and should be a fairly mild plan.
