if the users of the past could feel dbol off a cycke of 10mg/day... there is no reason one should not be able to start feeling it almost immediately with a higher dose that is more common today...
id bet that their built up levels were less than what some are experiencing nowdays in one dose...
i feel all orals pretty much work this way... i get a headache from beast within minutes lol... of course i dont immediately see all the effects right away... but with any oral you should be able to feel somthing within the first dose, granted its a decent ammount...
edit: the 'well being' feeling would be the first thing i get from dbol, followed by bloat within a few days and then strength gains withing the week...
