efedrine dramatically increases blood flow thus allowing for awesome pumps and a much leaner appearance. my mid section appears much slimmer while on 50-100mg efedrine.
what i do, when i want to stay ripped all day long, is take 100mg a day for 4-5 days pre 'contest', 100mg proviron for 4-5 days pre, and on the day of the 'contest' i take 50mg efedrine every 3 hours.
again, i dont compete and would hate to give advise that wouldnt work for you. this works for me, and works well.
bump for a good bro.
