Well if you get ketotifen, you can theoretically use clen for weeks on end without needing to switch to eca..You see the reason for switching clen/eca every 2 weeks is that your body becomes attenuized to each thermogenetic in that period of time. All Keto does is tells your body to regenerate the receptors that clen uses for thermogenesis without needing to stop or switch to something else
like eca. With that said i would be body wise if i was extending my clen runs with K, make sure i tapered down once i reached my goal BF%.
Remember i dont condone this i am just passing on what I would do if i was to use these prods.
