weight loss is slow using clenbuterol

[ojand]

so my 3 month bulk was at 4200 cals. gained like 5 pounds in those months natty. cutting at 3200 which should be fine. 1st week i did it clean
2nd week i started clen and today is the end of my 1st week of clen. iv lost 4 pounds in one day. after that my weight keeps going down 2 then up 1,etc. its frustrating. the clen is real as well. i did notice some stomach getting tighter. but is it normal? the up and down weight gain is frustrating
