there are too many fators that go into weight loss to be able to estimate fat loss in 7 days on eca for anyone,,it depends on your body type and what you do all day long and your response to ephedrine,,,every one lose fat on ephedrine,,,some lose is very fast some lose it slower,,but everyone lose bf% on it,,i suggest to be on hormones while doing ephedrine so you keep 100% of your lean muscle mass and not fade away
your bf% is around 20-22% in the picture,,inorder to be 8% NATURALLY you wil have to lose about 70lbwhich will put you at 170lb,,if you add clen,,abuterol,,or ephedrine you maybe able to be true 5-6% at 170lb according to the picture i see
