Bro I migth be a little confused here. It weren't you just asking about what a test only cycle would be like run "grammabol" style like Strasser reccommended. I though you were thinking about doing it, but hadn't yet?
Anyway to answer you question here's my take. Test alone based on overall size and strength gains, plus cost, is probably your best bet. Even a compounds like tren, drol, ot, or eq probably won't give you the same amount of gains once your pct is said and done. HOWEVER, like katz pointed out if you're down to spring for it synergy is the name of the game. So stacking test (less test then you used on "grammabol" plus one of those other compounds I mentioned will yeild more then EITHER run by themselves. That's why most people stack. It also means that less of both have to be used and with a lower dose comes less tendency towards side effects.
