clomid is much better for bringing back your own test levels
when you take AS your body slow's down your own test production some time's stop's it all together .but nolvadex will stop high test level that your body trys to convert estragen nolva stops the converson but does nothing for your test level raising
but the clomid doe's raise your test back buy causing your body to think their is no synthic test levels.but infact your body plays catch up to replace your own test.
why bring back your test level's beacuse thats how you keep your gains and your water and vitiams level and your endorfins to regular levels. putting you body back in check.
