To be honest it wouldn't be a course i would prescibe to people.
Testosterone and equipose are both from the Testosterone family and both have very similar characteristics. Both convert to estrogen, although equi does convert less than test.
You have given us 0 stats about you, weight, height, age calorie intake, macro split. Nothing.
And no, steroids do not make you loose body fat, eating less and moving more and putting on muscle makes you loose body fat.
And yes you will loose size when you come off as you are using very water retentive compounds. Nandrolone is well known for causing cellular swelling from increase water retention, that also spills over to joints and where ever there is fat water is an issue. Also when you are using more test than 3mg per kg, estrogenic side effects creep up and estrogen makes you retain water.
So looking at this cycle, and side effects like increased acne, you would have water and estrogen issues as well as androgen issues causing the acne. Would be interesting to know what your blood pressure is on this cycle especially if you have higher levels of body fat.
