I am about to start spring cutting. What do you think?

I am just over 6 feet - 215lbs
Workout 4-6 times a week

First thing in the morning I take 32mg ephedrine, 200mg caffeine + 25-50mg winn (the idea behind the winn is to limit muscle loss on low cal diet etc)(?)

I do cardio almost every morning 5-7 times a week 45min light bike ride before I eat anything.

Then immediately after cardio I eat iso-protein + skim milk -about - 250cal 40g protein

Then I continue to eat approx every 2 hours 300cal till I reach approx 2500cal and 200-250g protein.

I do tend to continue eating later then I would like to get the cal and protein all in – right up to bed time ¿

Any opinions or ideas/changes?

Thanks
